"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"

"We had five different things for Lou to fix, including a chandelier that needed to be lowered and made level. Lou rounded the oval links in the chain that held the chandelier and that made it level for the first time! He figured out why a ceiling fan was making noise and why another one wasn’t working at all. He also replaced part of our electric panel which had somehow gotten water inside and was corroded. We didn’t have the right part to change lights in our Faber stove hood, but Lou did, and quickly replaced them for us. We were really pleased with how knowledgeable and competent our electrician was and plan to call him again if we have any more electrical problems."

Electrical questions, answered by experts

Upgrading your amp service could possibly be a solution to tripped breakers. Circuit breakers in an electrical panel trip as a safety measure when something goes wrong with the current, and that’s often caused by plugged-in devices trying to draw too much current. Replacing the electrical panel with a new model and new breakers designed for higher amps can fix this problem.

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.

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.

If the fan doesn’t have a switch, connect the white wire from the ceiling to the white wire from the fan; connect the green wire to the ground wire; connect both black wires; and connect both blue wires. If yours has a switch, the white and green wires are connected the same way. However, connect the ceiling’s red wire to the light’s black wire and the ceiling’s black wire to the fan’s black wire. 

Grounding an electrical outlet can take as little as 30 minutes if you only need to replace the outlet or around two hours if you need to add a ground wire. However, more extensive electrical work will take longer, such as hiring an electrician to ground multiple outlets during the same service.
