"Chesapeake electrical just finished replacing an outlet on our 32 year old home. They also inspected the whole electrical system and offered options to upgrade our house to current standards. The technician, Brian, was very experienced and fixed our problem right away. Too many Christmas lights, too much recent rain and trying to charge an electric car on a 110 line! They came out the day after we called, the scheduler, Jackie, was very personable and determined to get this ordeal over for us. Our immediate problem was not too complicated but I can see down the road we may need more substantial electric repairs and we will be calling Chesapeake electrical for what we need. I recommend everything about their operation. Last comment and probably the most important comments moment, the cost was very reasonable. For someone who almost never uses an electrician, we are glad we found Chesapeake electrical. John and Jane, Ellicott City"

"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."

"The RaLo electrician did a great job running new wire to install my outdoor camlight. He also informed me of a number of other issues he noticed and gave me good price to address those issues as well. I definitely recommend their services."

"We had just moved into a newly renovated house. One by one the recessed lights throughout the house were burning out. The electrician from Kolb took his time diagnosing the problem until he found the cause. He was very thorough and patient. In the end it was some loosely concocted wires. We were very happy with the time he spent to get it right.

"Mark from Duke's Electrical Services was recommended by a friend in the home improvement business whose referrals have always been A+, and Mark certainly lived up to that reputation. Mark and his son were professional, punctual, and communicative. They texted before arriving and showed up exactly on time. Mark performed a thorough electrical inspection, took photos, and reviewed everything with me so I understood the condition of our system. I also asked about a few smaller projects, including a dock light switch and a deck remote-control switch that weren't working. Mark followed through on his promise to return, contacted me within a week, and scheduled the repairs. During that visit, I added two more switch replacements, and they completed all three jobs in under an hour. What impressed me most was their attention to detail. After finishing, they vacuumed the work area. As someone who appreciates cleanliness, that meant a lot. Professional, efficient, cleanliness, very rare find."

Electrical questions, answered by experts

A C-wire is typically blue, but don’t rely on colors to find which wire is which when it comes to thermostat wires. The C-wire may also be black, brown, or purple. Instead, if you’re looking for the C-wire, look at the thermostat panel for a wire connecting to “terminal C,” or call in a pro to help you look for a C-wire.

It prevents electrical surges, protects your home from things like electrical fires, and prevents you from getting shocked if an errant surge runs through your power line. Without grounded wires, your appliances could also get damaged during lightning storms.

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.

You can distinguish the amplitude and voltage of most outlets by looking at the shape and positioning of the holes. Other features like buttons, switches, and USB ports help identify electric outlets, too. Use labeled images, like the ones we’ve included above, to cross-reference with your outlets.

Knob and tube wiring is old, and its casing is brittle. This means that it's possible to receive a dangerous electrical shock if you touch a live wire and essentially become an electrical pathway. Although the scenario is unlikely, touching any K&T wiring is simply not a good idea in any instance. Leave any wire handling to the professionals.
