"The work done was fine. The initial quote was padded with about $450 of work I did not need, which I declined. This eroded my confidence that the work I agreed to was priced fairly. Felt it was overpriced."

"I had four electrical outlets that were not working. I scheduled an appointment with Tony from Trident Electric. He called me about an hour before my appointment to see if I was available so he could come early. I was, so he came right over. He immediately got to work troubleshooting my electrical problem. It was a complicated problem, because there was a disconnected or broken wire somewhere in the wall. However, he was able to fix the problem, and all of my electrical outlets are now working. Tony cleaned up after himself, and he is very courteous and knowledgeable. And this was all done for a very reasonable price! I will definitely call Trident Electric again for any electrical problems."

"Electrician was prompt and friendly. Worked very quickly. I had purchased a full day and he had gotten through most of my items by the mid-day point. A couple of my ceiling fan light kits were not working properly and needed a little extra attention to troubleshoot. Also the doorbell I had purchased needed a transformer in order to complete install. The tech was eager to leave and said he would come back another day if wanted him to. When I tried to schedule a follow up, he was booked up for at least the next 3 weeks. I was disappointed that since I had paid and booked for a full day, he didn't stick around long enough for me to run to the store and get whatever supplies might be needed so the job could be finished that day. Also after he left, we realized one of the regular light fixtures that was installed wasn't working. Considering I paid for a full day and only got a half day of work, and had to pay someone else to come back and finish the job, I don't feel like I got a great deal."

Generator Install questions, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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 can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
