"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.

Electrical questions, answered by experts

Regular inspections, avoiding circuit overloads, and updating wiring when needed help maintain efficiency.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

The major difference between a GFCI breaker and an AFCI breaker is that a GFCI breaker protects against fatal shocks while an AFCI breaker prevent electrical fires. A GFCI breaker senses when the electrical current to ground is overloaded and trips to prevent major accidents or injuries. AFCI breakers trip when it detects dangerous electrical arcing.

In most cases, line wires are located at the bottom of a panel or device, while load wires are located at the top. Line wires are generally black, while load wires are typically red or black. To tell for sure, you can use a multimeter or volt pen to test the wire. A live or line wire will always carry a charge, while a load wire will only carry a charge when it’s in use.

The best place to put an electrical outlet depends on your needs. A good rule of thumb is to install outlets every 6 feet in large rooms. Hallways over 10 feet long need one electrical outlet minimum. 

If you find yourself needing extra plug-ins for all of your gadgets, you may want to increase the number of electrical outlets in your room. When adding outlets, keep in mind that older homes could have outdated electrical panels. In these cases, you may need a pro to upgrade you from 100-amp to 200-amp service before increasing the power load.
