"Power Up Electric did outstanding work rewiring my whole house after an unfortunate electrical fire in my garage five years ago. They were very efficient, neat, and took real pride in the quality of their work. For the last five years they have been my go to electrical company. Telephone response is prompt, service is offered quickly, prices are fair and every electrician who has come to my home as been reliable. When friends and family need to have electrical work done, I always recommend Power Up Electric."

"Electricity was needed for a new control panel for my backyard sprinklers, and I needed a couple of light fixtures replaced in my house. The gentleman showed up on-time and quickly took care of everything in three hours, which included making a run to the hardware store for a part. The price was very reasonable since I used the promotion on Angie's List. Moving forward, they will be the first people I call for electrical work."

"Excellent! Haik and his crew had the unfortunate task of correcting an illegal job done by another electrician. Haik and his crew immediately came to work on our condo. They were courteous, punctual, and very professional. The work was inspected, as required by law, with no citations. As a last minute request, they also upgraded 3 of our outlets and replaced a light switch without changing the amount to our original contract. Their quote was competitive and I felt good working with an honest company. What Haik said they would do was promptly, efficiently, and correctly accomplished. A definite gold star and will not hesitate in calling him if any electrical work needs to be done."

Electrical questions, answered by experts

Homeowners should avoid replacing a circuit breaker without turning it off. While you technically can replace a circuit breaker without turning off the main breaker—and professionals can and do—it’s only safe for electricians to use this process. Working with a live panel is extremely dangerous if you don’t have experience working with electricity. Always follow safety measures to avoid electrical shock.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

You may be able to spot common electrical dangers yourself, but it’s best to hire an electrician to diagnose and fix the issue. For example, you may be able to DIY small electrical fixes, like replacing an electrical outlet, but major electric repairs or replacements should be left to a professional electrician.

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

A C-wire is typically blue, but don’t rely on colors to find which wire is which when it comes to thermostat wires. The C-wire may also be black, brown, or purple. Instead, if you’re looking for the C-wire, look at the thermostat panel for a wire connecting to “terminal C,” or call in a pro to help you look for a C-wire.
