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.

Just Looking for Ways to Save Money? Marbec Enterprises Can Help!

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!

Marbec works with everything from large home electrical installations to installations as simple as switches. One popular install is dimmer switches, which are a favorite in many homes, both for their energy-friendly operation and their style.
Dimmer Switches: Why Install Them
Dimmer switches are an inexpensive item that many homeowners love to add to their electrical setup at home for many reasons.
Dimmers save power, decreasing energy usage significantly and resulting in a lower power bill.
They set the mood and a unique ambiance to a home, whether it’s in the kitchen or the bedroom.
They’re easy to install, even for homeowners.
Dimmer Switch Installation Tips
Even an easy installation can turn tricky, which is why you should call your local electrician at Marbec to ensure that your dimmer switch install is done correctly. Still, if you feel comfortable doing the installation yourself, here are some tips for a smooth and pain-free dimmer switch installation.
Check the wattage limits on switches to prevent overheating and overloading of the circuits. Dimmers can handle anywhere from 600 to, in some cases, 2,000 watts of power. The key is to not run too many lights on the switch and risk overheating or overloading it, which can be dangerous. You will know if there is something wrong with one of those scenarios if, when you touch the dimmer after installing it and running it, it’s hot to the touch. Warm is normal; hot is not. This is one of the reasons why you should consider calling the best Dallas electrician to help oversee your installation.
Make sure that there are no other dimmers connected to the same circuit. Much like having too many appliances in the same circuit can be a danger, too many dimmers can cause overloading that results in dangerous circumstances and costly repairs.
Never use fluorescent bulbs with dimmer switches. Fluorescent bulbs will not work with dimmer switches. If you really want to use fluorescent lights, you can find some for a pretty hefty price that will run on dimmers.
Ordinary dimmer switches cannot run devices that rely on a motor, like ceiling fans. Ceiling fans are set to run at a specific, predetermined wattage and therefore they are not compatible with dimmer switches, which gradually adjust wattage.
Older styles of dimmers can sometimes interfere with audio equipment, creating a humming or whining noise. A Marbec electrician can quickly recognize this as a sign that the dimmers are too old. To resolve this issue, you must either install a new dimmer or install a noise filter.

Making sure that your house is safe & productive for many years

If you’ve ever watched the show “Holmes on Homes” on HGTV, you’ve likely seen the problems associated with old or faulty wiring.  Mike Holmes tends to get very agitated by safety issues, and for good reason.  Each year, over 40,000 homes suffer fire damage due to home electrical problems.  These electrical fires account for hundreds of deaths and thousands of injuries.  And what’s the main culprit?  Old wiring!

If you live in a classic home built before 1940, chances are you have old wiring in the house.  You may have knob-and-tube or Romex wiring, both of which can become brittle over time.  The insulation dries out and starts to crumble, causing the inner wire to become exposed. The cloth insulation around the wire deteriorates with age and eventually becomes unsafe.

But perhaps one of the biggest threats of Romex and knob-and-tube wiring is that these types of wires aren’t grounded.  That means if one of your appliances shorts out, you could become the path to the ground for the electricity.

Even if your home is only 20 or 30 years old, you could still experience electrical problems at home due to a lack of capacity.  Most homes built more than 10 years ago are not designed to handle the amount of electronics we use today.  Think about it:  if your house was built in 1980, it was built before home PCs and laptops and HDTVs and surround sound and all of the other toys and gadgets we use today.  These appliances can draw a lot of power, and your current electrical wiring may not be up to the task.
If you own one of the houses that’s more than 20 years old, it’s a good idea to have a licensed electrician come out and take a look at the wiring.  He or she can make sure that your house will be safe and productive for many years.
