"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."

"Mr. Johnson and his crew have performed a fewjobs from lighting installations, to doorbell repair, to rewiring. Every job has been done well and at a reasonable price. The workers were respectful and very helpful at explaining the work they did before they left. What really set this outfit apart is Mr. Johnson himself. He always returns calls, his crews show up on time and perform the work expediently. On top of this, when I have had questions about other electrical concerns, Mr. Johnson takes time to have a phone call to consult on the issue. Mr. Johnson and his company are of high integrity and I would highly recommend them for any residential electric 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 FAQs, answered by experts

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

To fix a tripped light switch, locate your home's electrical panel and identify the tripped circuit breaker. It will be in the "off" or neutral position. Flip the breaker entirely to the "off" position, then switch it back to the "on" position. If the breaker trips again immediately, there may be a short circuit or overload in the system, requiring further investigation. If the switch still doesn't work after resetting the breaker, check for loose wires or faulty components in the switch itself. It is always best to consult a licensed electrician for persistent issues and when in doubt.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
