"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."

"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.

Electrical questions, answered by experts

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.

A light switch can stop working for several reasons. Typical causes include a blown fuse or tripped circuit breaker, both of which shut off power to the switch. Worn-out or faulty internal switch components can also prevent it from functioning properly. Loose or disconnected wiring within the switch or electrical box is another frequent issue. Additionally, switches may fail due to age, excessive use, or physical damage. In some cases, problems with the light fixture or bulb itself might be mistakenly attributed to the switch.

The easiest way to determine the amperage of your electrical outlets is to check the corresponding breaker in your home’s breaker panel. The number is likely noted on the circuit breaker. If that fails, it’s possible to tell 15-amp and 20-amp outlets apart by looking at them. Fifteen-amp outlets have two vertical holes, while 20-amp outlets have one vertical hole and one T-shaped hole. 

Yes, you can connect two extra outlets (or more) to one outlet if the total load on the circuit allows for it. If you have a 15-amp circuit, electrical code allows up to eight outlets or light switches. But if you’re dealing with outlets in the kitchen and bathroom, you may not be able to have as many. Kitchen and bathroom appliances often need higher amperage. You can also change a single outlet to a double outlet by cutting a larger hole in the drywall and replacing the outlet with a quad receptacle.

Yes, you must use the proper wire nut that fits your wire gauge. Using a wire nut that’s too big or too small can cause your connection to fail, short circuit, or disconnect entirely. Ensuring that you have the proper wire nut size will guarantee that your connection lasts as long as possible.
