Understanding AC vs. DC

Almost everything nowadays operates on electricity. The modern conveniences that drive our world depend on electricity. Without a constant supply, our world grinds to a halt, as massive blackouts have proven in the past. Electricity has two forms in modern electronics: AC and DC.
AC [alternating current], is most frequently used in devices that require high amounts of power to operate.
DC [direct current], is more commonly found in devices requiring smaller amounts of power to operate.
Understanding AC vs. DC
Direct Current
DC was the original electricity that was created by Thomas Edison. This style of electricity sends a current in only a single direction, from a power source and to the power source again in a loop. Today, DC is used to power electronics that require batteries. Any device in your home that uses batteries uses DC current. Interesting to note, if your battery is plugged in to the power supply to recharge, it transforms AC current into DC.
Direct current is also used in manufacturing situations where electricity is generated on site for personal use. Factories and mills that require vast amounts of energy often create their own DC current to power their machinery. Most commonly, DC is found in steel mills, aluminum production, and is used to power mass transportation in large urban centers in the form of electric streetcars.
Alternating Current
AC power is easier to generate, which is why we use it as our standard electricity nowadays. The alternating current design allows energy to flow in both directions, making electricity easier to create and use in society. Regardless of where the current is moving, it is always moving in both directions at once. This results in current being present at every point in the power grid at every time as long as the connection to the generation unit is intact. The power that comes from the power plants, down the lines to our homes, is always AC in nature, thanks to the way our modern power grid is set up.
The power grid operates by creating AC current and sending it down the power lines. This current can be at whatever intensity the power company chooses.
Frequently, the electricity coming from these lines is far too powerful to be used in our homes. The transformers that we see on power poles transform the electricity from its high-powered state into something that our homes can use. Without the transformers, we wouldn’t be able to use the power that our society depends on.
Regardless of the style that we use in our devices and our homes, electricity plays an important role in society. Without both AC and DC electricity, we wouldn’t have those things that make modern life as comfortable as it is.

Questions? Call Marbec Electric.

The hot water heater represents one of the greatest hazards in the modern home, yet far too many homeowners have never read their heater’s owner’s manual. Common dangers associated with these household appliances include severe burns from scalding water, electric shock hazards, explosions, and fire.
Because most water heaters reside in closets, basements and garages, and are for the most part hidden from our daily lives, many aren’t as aware as they should be of the maintenance and precautions which are necessary for safety. Many homeowners don’t know for instance, that they should drain and flush a hot water heater every six months, to prevent sediment buildup. Others are unaware that hydrogen gas can build up inside electrically heated hot water systems when they remain inactive for two weeks or more. Hydrogen buildup requires carefully performed procedures to safely remove this flammable gas from hot water pipes. Many don’t know how and why water softening systems shorten the lives of water heaters, or that every electric hot water heater should be properly grounded with the correct gauge of copper wire. Marbec Enterprises can do this.
Correct safety and maintenance measures covered in a water heater’s manual are extremely important for household safety, so every homeowner should study this to learn how to properly maintain their hot water systems. It’s also extremely important to understand the electrical dangers these appliances represent. Because a hot water heater contains electrical heating elements immersed in water, these elements can deteriorate with age and short out electrically to the water heater’s metal casing. When this happens, it’s possible to receive a severe and perhaps fatal shock when touching the hot water heater’s housing or connecting pipes. If you do not have the necessary skills to work safely around high voltage electrical conditions, you should always call a professional electrician at Marbec Enterprises any time you suspect a problem with your hot water heater or when you have any other electrical concerns. When any questions about electrical safety arise, please call Marbec Enterprises. Our electricians are trained and equipped to identify any type of hazardous electrical condition, and to determine the proper repair procedures.

Updating Your Home’s Electrical Infrastructure

With the explosion of home renovation shows such as House Detective, Holmes On Homes and Income Property , you would be hard pressed to find the person who isn’t aware that any renovation of an older home would require the specialized services of a licensed, qualified electrician. Often conjuring up images of the older, ‘quaint’, 40+ year-old home, the word “renovation” has almost become synonymous with a neglected home in disrepair, complete with bundles of wiring that could pass for extension cords. Obvious stuff that would appear glaringly unsafe to the average person.
What doesn’t come to mind is your typical, one or two-story home built anywhere from the 1980's to early 2000's.  But in today’s housing market, doing a kitchen and bath remodel could mean the difference between a sale and seeing no movement at all . Whether it’s to compete with newly built homes in a weak housing market or to increase the value and enjoyment of one’s home, a homeowner would be prudent to consult a licensed electrician when making any updates to their home. There can be unforeseen dangers when combining newer, modern appliances and lighting with existing wiring, and a licensed electrician from Marbec Enterprises can inspect and update your home’s electrical framework, ensuring its safety and increasing energy efficiency.
In a case of one trend bringing about another, the increasing popularity of in-home offices and theater rooms has  sparked the inclusion of structured wiring, or heavy-duty electrical and data cables designed to manage the latest (and yet-to-be-invented) electrical devices. Take into account that almost 50% of new homes built in 2008 included structured wiring and you can see that this trend could very well become the norm in the near future.
For questions on updating your home’s electrical infrastructure, call an electrician from Marbec Enterprises.

Broken Electrical Outlet

When a light switch or electrical outlet doesn’t function correctly, a professional electrician from Marbec Enterprises can trace this back to a variety of causes. First, it’s possible this non-functioning device was never connected to the wiring in your building. Secondly, the circuit affected by a switch or outlet may not be completed because of another component. For example: A switch may control an outlet which is unoccupied by a lamp or any other electrical device. Also, an outlet may be connected to a switch which is in the off position. A third cause might be related to a defective breaker, or a breaker which was tripped or turned off, but never switched back on. However, a fourth possibility may relate to a much larger problem.

Sometimes, a switch or outlet fails when it is damaged by arcing. If the arcing was caused by a connection to aluminum wiring, great potential hazards exist. If your home or building was constructed or renovated before 1972, or during the late sixties, it may contain aluminum wiring. Aluminum wiring was used legally during those years, but outlawed for installation in new homes, commercial buildings, remodels and renovations after it was identified with conditions which could lead to electrical fires.

Although aluminum wiring itself is generally no more hazardous than copper, its splices and connections with other metals present a real hazard because they can become corroded and begin arcing. Because arcing in these connections can lead to fire within surrounding materials, aluminum wire was discontinued. However, many homes still contain aluminum wiring, and research conducted by the Consumer Product Safety Commission (CPSC) reveals that buildings with aluminum wiring pose a fire risk which is 55 times greater than the risks with similar structures wired with copper. So, if you discover an electrical outlet or switch which doesn’t appear to be functioning correctly, it’s possible this outlet or switch was damaged by a connection with aluminum wiring. If you have safety questions about this type of problem, or any electrical concerns regarding your residence or commercial building, please contact an electrician at Marbec Enterprises. Our licensed electricians are trained and equipped, and they can repair any type of electrical problem

LED lighting

Short for “light emitting diode” and introduced commercially in the early 1960’s, the first LEDs produced low levels of red light, and were first used as indicator lights on electronic equipment. As their name suggests, LEDs are diodes, and will operate on both AC and DC electric current. In the mid-seventies, the first digital watches featured LED displays, and in the following decades, LED technology expanded into many applications as LEDs producing most of the light spectrum were developed, from infrared to short wave ultraviolet.
Most notable has been the development of LEDs producing extremely bright “white” light. Although these “white LEDs” first produced very cold bluish white light, their output has become more sophisticated, and LEDs are now available which produce “neutral white” as well as “warm white” light. The latter light color is very pleasing, and quite similar in color temperature to light produced by halogen lamps. Another term for LED lighting is “solid state lighting,” as opposed to “hollow state lighting” which describes nearly every other type of lamp or light bulb. LEDs have seven distinct advantages over halogen lamps, and ten advantages over fluorescent lamps. Smaller in size, quicker in response time, and cooler in operation, LEDs last 100,000 hours or more – longer than both halogen and fluorescent lamps. They are more efficient in their consumption of electrical energy than either halogen or fluorescent lighting, and they are safer than other lighting because LEDs can operate on much lower voltages. Also, because they have no delicate glass envelope or fine wire filaments, they are much more resistant to shock and vibration than halogen and fluorescent lamps. Because of their low voltage operation and resistance to impact and vibration, solid state lighting is rapidly replacing all other forms of RV, truck, marine, aerospace, and automotive lighting.
Very recently, solid state lighting is also appearing in homes and offices. And this is where its additional advantages over fluorescent lamps really shine. First, when operated from a DC power supply, solid state lighting doesn’t flicker like fluorescent lighting, which lends to a much more comfortable environment for individuals sensitive to flickering light. LEDs designed for visible spectrum illumination produce no harmful UV emissions, making them safer for our eyes and for artwork which can fade from exposure to ultraviolet light. Most importantly, LEDs contain none of the hazardous mercury vapor present in all fluorescent lamps, including CFLs (compact fluorescent lamps). Because of the mercury vapor they all contain, fluorescent lamps of all kinds represent a serious and potentially dangerous hazard in our homes, schools, hospitals, public spaces, and offices. They also represent a serious ongoing disaster as we dump literally tons of mercury from discarded fluorescent lamps into our environment every year. So, as prices for LEDs continue to drop, we should all hope to see solid state lighting replace all forms of environmentally hazardous fluorescent lighting. If you are interested in a mercury free home or workspace, please contact Marbec Enterprises.

Affordable Home Makeover

Working with thousands of homeowners Marbec Enterprises has taken part in just about every home improvement project you can think up. Unfortunately, many homeowners’ plans for their dream home makeover have been put on hold due to a lack of funds. Fortunately, there are things that you can do to perform an affordable home makeover for a lot less than you might think.
By far, the most dramatic way to change the look and feel of your home, without a complete makeover, is by simply changing the way it shines! The lighting in your home plays a huge role in the first impression that you get when you walk into a room, and can be one of the major determining factors in setting the ambiance and overall feel of the room. By installing the proper recessed lights and pendant lights, along with chandeliers in your home, you will be able to accent the existing décor you already have.
Recessed can lighting will clean up your ceiling and do away with unsightly light fixtures installed everywhere.  When installing a recessed can, the type of trim is essential to maximizing the amount of light that you can get in an area.  A baffled or recessed trim will create a spotlight effect, whereas a flush mount trim allows the light to start at the ceiling and move throughout the room.  This gives a much more even look upon finished product.  Any electrician that has done a lot of installations should be able to guide you in the proper direction so that the style of lighting that you are looking for will be achieved.  Be careful attempting these by yourself, drywall will need to be cut for installation, and you never know where a wire or plumbing pipe may be hiding.
Pendant lighting is also making a big hit right now.  This type of lighting can be used to decoratively light up kitchen islands and kitchen bar-type counters.  This is a creative way to separate your kitchen from your living room.  Typically, homes are not pre-wired for these lights, and wiring will have to be added before they can be installed.  We highly suggest when wiring for these lights, that a new switch leg be installed for independent control.  As always, installing new wiring to your existing electrical should be done by a Marbec electrician.
Depending upon your tastes in furniture, replacing a living room of furniture can cost ten or twenty thousand dollars! Updating the lighting in the same room can drastically change the look and feel of the room, often for less than one thousand dollars. Replacing lamps and old fixtures with recessed can lighting and a classy chandelier can transform a dim dreary space into a room that you can be proud of. Switch out the chandelier with a nice ceiling fan that compliments the room, and you can even do your part in going green with the energy savings that come with using a fan to circulate the air in your home instead of relying constantly on your energy hogging air conditioning system!
If you need some help in creating your own affordable home makeover by replacing the out of date lighting in your home, contact an electrician at Marbec Enterprises to discuss the options available to upgrade.

Risk Of a Short Or a Fire?

Tripped circuit breaker: many of us have experienced them at some point in our homes, yet instead of asking ourselves, “Why Do Breakers Trip?”, we reset the breaker without much thought. Before flipping the switch back over to the “ON” position, however, it’s important to understand why the breaker tripped in the first place, and what can be done to keep it from happening again.
At Marbec Enterprises we understand the danger of ignoring the warning signs of a tripped circuit breaker. But first, you need to know what a breaker does and how it works.
Simply put, a home or business circuit breaker is a safety device that monitors the amount of electrical current going through the electrical wires in your home and shuts off the circuit if too much electricity is being pulled through it, or if there is any disturbance in the current that could result in a fire. Whereas a fuse performs the same task but can only be used once, a circuit breaker can perform over and over with the use of a switch that trips to indicate when it has effectively cut off current to a particular area. So, Why Do Breakers Trip and what kind of things could cause a circuit breaker to trip? Some of the most common causes of a tripped breaker include:
Overloaded circuits: Often times, when there are too many appliances plugged into an electrical circuit, the wiring reaches unsafe heat levels due to pulling more electricity through the circuit than it is designed to accommodate,  and puts your home at a risk for a fire. That’s when the circuit breaker trips, shutting off everything that is plugged in to that circuit, preventing overheating, reducing the risk of fire. This happens often in older homes, where the wiring was not designed to withstand the power of modern appliances.
Electrical shorts: Other times, a tripped breaker can happen as a result of an electrical short, due to old and worn out appliances, with damaged wiring in your home. Common causes of electrical shorts in the home include faulty wiring, rodents or other animals chewing through your wires or aging wiring in older homes. Because of the large range of possible culprits, diagnosing an electrical short can be more difficult and therefore should not be ignored. Determining whether a short is in an appliance may be as simple as disconnecting your appliance and resetting the breaker, if it continues to trip, definitely call a Marbec Electrician. Often times, it’s when an appliance is not being used and the electrical short is happening, that it is much more complex and requires professional help.
Because of the many reasons why your circuit breaker could be tripping, and because of the purpose of the circuit breaker, you should never take a tripped breaker lightly. It’s important to understand that the circuit breaker is a safety device; simply switching the circuit back on without investigating the culprit can become costly in the long run and, in many cases, extremely dangerous.
If your breaker trips consistently, chances are there is a potentially dangerous electrical issue that needs to be looked at. Call Marbec Enterprises to make sure that your home is safe and free from the risk of a short or a fire.

Home Systems

In the current economic climate, in which everyone is trying to save money, you might not know that a Marbec electrician can help! Sometimes, saving money is as simple as finding a simple idea that makes your life run more efficiently. When it comes to electricity, one of the best and least utilized ways to save money and energy is by putting your lights on a timer.
As any Marbec electrician can tell you, timers are extremely useful! You can use them to turn lights on and off, whether or not you are at home. This makes it easy for you to appear as though you are home when you are on vacation, or control your Christmas lights, but those are not the only instances in which timers are a good idea. For instance, you can set a timer to make your lights turn off after you go to bed, and come back on in the morning. This makes a great backup alarm clock, and also ensures that you don’t accidentally leave lights on all night. You can also set them to turn off lights when you are at work, in case you forget.
There are two types of timers for home systems: mechanical and digital. Digital timers look good and are very useful, with several automated features. Even though they can be installed by someone who is not an electrician, homeowners may feel more secure hiring a professional, because digital timers have sensitive electronics inside that require a neutral wire that switches do not. A Marbec electrician will be able to choose the right digital timer for your needs, competently install it, and even change out the switch plates if necessary.
Mechanical timers are less common than digital, but are very useful. They are often used to control swimming pool equipment and outdoor lighting. In addition to controlling lights, they can be attached to a water heater to keep it from running when you don’t need hot water. This can make a huge difference in your electric bill!
The main difference between mechanical and digital timers is that mechanical timers are typically larger and sturdier, and can handle a larger electrical load. Digital timers are more aesthetically pleasing, and will fit better into your home’s décor. A competent Marbec Enterprises electrician will advise you as to which timer best suits your needs.
Whether you have an electrical problem, or are just looking for ways to save money on your electric bill, Marbec Enterprises can help!  Visit our website or if you would prefer, you can always call us to schedule an appointment today!

Chandelier Installation

Chandeliers look beautiful when installed in your home, but the process of properly installing them should be left to a qualified, experienced electrician Plano homeowners can trust. Proper installation of a complex electrical fixture like a chandelier is best left to a licensed residential electrician who understands the intricacies of adding a chandelier to your home and who can make sure that the process is carried out safely and efficiently so that your fixture has a long life with little need for repairs. Instead of finding an electrician homeowners sometimes opt to do a chandelier installation themselves. What they don’t realize is that chandelier installations are very difficult and complex, and as a result it’s always best to contact local electricians who are experienced to do the job. installation chandelier that is installed incorrectly can mean many costly and dangerous complications in the future. Follow these important electrical tips to ensure your chandelier is properly installed in your home.
1. Hire an electrician who is experienced with this type of installation and its wiring, as it is very different from many of the other fixtures in your home. Homeowners are often unfamiliar with the proper wiring for a chandelier; as a result, they end up damaging the fixture when doing the installation themselves. Experienced electricians know that the side of the wiring with the ridges and bumps is the “power out” side and the smooth wiring side is the “power in.” Getting those mixed up can cause serious damage to your wiring and your equipment.
2. Make sure that your electrician follows the manufacturer’s order of instructions for fixture installation. Steps missed or skipped can cause serious problems and result in wasted money and time, as well as risky complications. For example, it’s important for your electrician to remember that, when installing a crystal chandelier, the fixture must be installed before hanging the crystal. Otherwise, the fixture will be too heavy and fragile to install.
3. Be mindful of weight limits when it comes to chandeliers and your ceiling. If the chandelier weighs over 100 pounds, chances are you’ll need an additional complex support installation in your ceiling to ensure that there’s enough support to hold the weight. Not being aware of these weight limitations can cause major problems with the installation.
4. The residential electrician you hire needs to make sure that the canopy cover is properly installed and adjusted to the correct depth before hooking up the chandelier’s wiring. Placing the canopy cover flush to the ceiling may result in twisted wiring and a bad connection.
5. Your electrician should know that chandeliers are hung from their chains, not the wiring itself. Hanging the chandelier from the wires can stretch them, causing a fire hazard. Chandeliers, in any case, are not designed to hang from anything other than the chains they come with.
