"I have been searching for electrician to come out and fix our voice, Network, and camera lines for our small business. I searched for weeks and wasn't so lucky. I came across homeadvisor.com and saw Progressive Consulting. I gave him a call, 10 minutes later her arrived at my business. I explained what I wanted and he already knew what it would take. He gave me a quote 30 minutes later. Very affordable price for the work he provides. The next day at 9:30 am he came out and completed the job just as estimated nothing less nothing more. I would HIGHLY recommend this company to anyone looking for electrical work. Quality and affordable couldn't ask for anything else."

Electrical questions, answered by experts

You can check if an electrician is licensed in California by using the online check a license tool offered by the Department of Consumer Affairs Contractors State License Board. You have the option of searching by the license number, the electrical contractor’s name, or the name of the business to determine the electrician’s status.

Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too. 

You should never wire neutral and ground wires together at a light switch. Not only is it unsafe, but it’s also incorrect. The neutral and ground wires perform separate functions in an electrical circuit and should never be swapped or wired together at a light switch, light, or outlet. 

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

Yes. A pellet stove should have its own 110V outlet and dedicated circuit breaker. Otherwise, it could overload the system. Pellet stoves can create major fire hazards if they aren’t wired properly or have to share circuits. Get in touch with a local electrician or pellet stove expert if you need to run new wiring for a pellet stove.
