"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 FAQs, answered by experts

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
