"The two service men who came to complete our "electrician for a day" deal where just flat out awesome. We gave them a fairly long list of items that we wanted done that was quite varied in nature (replacing electrical outlets, installing dimmer switches, exhaust fan timers, re-wiring a light switch, installing a light fixture, installing TV on the wall, and more). They worked through the list quickly and efficiently, explained things about our electrical system along the way (which was very helpful) and were exceptionally courteous and professional. They also worked very well as a team, dividing and conquering all of the items on our list. Recommend them without reservation."

"not just professional efficient! Unbelievably fair priced literally less than half of what a major competitor on this site quoted using my own parts and my own wire! Just because there are any energy list doesn’t mean some people won’t try and rip you off and fools will pay it. Mr. NAGY is a professional and very ethical. I’d recommend hiring him again and again!"

"Everything about Able Electrical Services service was superb! I was in a jam, and Able Electrical Services came to the rescue. Both of the mechanics that assisted were excellent. Russell Ridgway was the primary mechanic and he was amazing! His work is superior and he exceeded my expectations every step of the way. For example, I needed electrical outlets to connect install a wet bar. He measured the wet bar and installed the outlets exactly where they were needed and ensured sufficient power was added to accommodate a kegerator and mini-frigs. I highly recommend Able Electrical Services and hope I never need to use any other electrician."

"There was quite a lot of work to be done. They came out they put a new panel in, they run new wires, they sorted out some minor electrics in the attic, they got some connections and so that they system was therefore complete for the contracting firm to come in and do their part. We chose them because we've used them before. We've done some minor electrical work with them when we had first arrived."

"I highly recommend CT Smith Electrical LLC , 410-984-8693, because of the fantastic job they did in installing a ceiling fan, including the wiring and switches. Also, I had recessed lighting put in my hallway. The gentlemen showed up on time and were very friendly and professional."

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

A wire stripping tool is the easiest way to strip sheathing or plastic insulation from electrical wires. A self-adjusting wire stripper cuts and removes the sheathing without damaging the core wire.

While not always necessary, wiring your circuit breaker in a certain way can ease both the installation process and use afterward. For starters, you’ll need to install the electrical panel so that the main service knockout aligns with the cable conduit. If they aren’t aligned, you may not have sufficient working space to finish running the wires. Using cable trays, on the other hand, gives you a bit more freedom to and flexibility in where and which direction you install the wires. At the end of the day, the power flow will be the same whether the cords run up or down.

It's less expensive to run power overhead because it doesn’t require excavation, and the power cables are less costly. However, underground electric service is better protected from weather and general wear and tear, so it’s less likely to get damaged. When determining which way to run power, consult a local electrician to get an expect opinion.

If a 240V appliance is connected to a 120V outlet, the lower voltage will cause that appliance to receive insufficient power. This may result in reduced performance, malfunctions, or even damage to the appliance's components. Depending on the size of your electrical circuit, you’ll likely need to reset a tripped circuit breaker at the very least.
