"Carlos showed up early to my office on a Saturday morning, and finished the replacement of the electrical panel (circa 1940's) with a more up to date one with extra breakers for future expansion, all in record time. He was neat, tidy and efficient, and explained everything he was doing without being asked, in easy to understand "layman's" terms. I will use his services for any future electrical work and will gladly and enthusiastically recommend him to any one I come into contact with who asks for a recommendations for someone to help them with their electrical needs."

"Joe's Electric returned my care within minutes of me contacting them. I had a technician in my home in 1.5 hrs. Who quickly identified and fixed the problem within 35-45 minutes. They saved me from losing a whole day of work and it was worth the cost vs loss I would have incurred."

"The work was done professionally and done on schedule. Raymond the manager gave me all the information I needed before the start of the project . The communication was timely and valuable throughout the project. The main reason I hired Excellent Electric is because Raymond also made recommendations that help to reduce the cost of materials and labor. I interviewed three other companies and all gave me competitive prices, but the recommendations Raymond gave me, set Excellent Electric above the three other companies I interviewed. I will hire Excellent Electric again and recommend this company."

Electrical questions, answered by experts

The life expectancy of a circuit breaker is 30 to 40 years. However, how long your circuit breaker lasts depends on the condition of your electrical equipment, the amperage, your electrical consumption, and more. A breaker box that frequently trips from overload will last much shorter than a breaker box with the proper amperage for the number of devices and appliances in use. If your circuit breaker trips frequently, and you have also increased your electrical consumption, it may be worth upgrading your electrical panel to extend your electrical system’s lifespan—and save you the hassle of frequent power trips.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Yes, many professionals offer wiring upgrades as part of their services, including upgrades to support VoIP, fiber optic, or high-speed internet connections. It is recommended to confirm the specifics with your contractor.

The standard voltage for United States power outlets isn’t shared around the world, and neither is the shape of the power connector. This is why you need travel adapters when spending time abroad. Where the United States typically uses 110/120V outlets, outlets in Europe typically use 220/240V. Power outlets can vary in other ways around the world, too. Not everyone uses the 60Hz frequency, for example, and not everyone even uses AC power in outlets. Always do your research when traveling to see what you need.

While it’s not possible to put a main breaker in a main lug panel, it’s possible to convert a main lug to a main breaker. Converting to a main breaker panel offers increased safety, simplified control, compliance with building codes, and adaptation to changing electrical needs, especially when adding new circuits or upgrading the system.
