"B and D is very professional in all aspects of the work. Always on time, precise in his work, treats the job like he was working on his own home, has a great play list on his radio, and ALWAYS leaves the work site clean and neat. He even used a blower to clean off the front porch every night whether he worked on it or not. I have no reservations in recommending B and D for all aspects of your job. High quality!"

Electrical questions, answered by experts

The color of your cable will help you to identify its function. In the U.S., the National Electrical Code (NEC) designates the color code for electrical cables. “Hot” cables are black, red, and blue. In cases of higher voltage lines, orange might also be used to indicate a hot cable. White or gray indicates a neutral, and green or green with a yellow stripe indicates a ground.

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

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.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.

Yes, you can plug an extension cord or an outlet extender into a GFCI outlet. The GFCI outlet will still be able to protect your system in the same way.
