"I had a car charger installed and was really happy with the work. He was responsive, showed up when he said he would, and the install came out clean and professional. Everything was explained clearly, the work area was left neat, and the charger works exactly as it should. Definitely someone I?d recommend if you need electrical work done."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

The hot wire is typically black, but it's essential to use a non-contact voltage tester to confirm the electrical wire color code before working on it. Neutral wires are typically white. It’s vital to determine which wire is carrying electrical current before proceeding with any electrical work.

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.

Black is the standard color for hot wires, which transfer electricity to your outlets and switches. Red wires are also hot wires. White (and sometimes gray) wires are considered neutral, delivering power back to the panel. Finally, green wires, which are sometimes bare copper, are ground wires, used to ground an electrical circuit and prevent electrocution.

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.

GFCI outlets help prevent dangers from ground faults that can cause shocks. This is a different issue that a ground circuit can’t fully address. It’s best to use GFCI outlets combined with ground circuits for complete protection for you and your electronics.
