"Jesse's quote for my electric vehicle charger installation was very fair. Less than two other quotes. He communicated well and his work was completed on time. I would hire him again."

"We had 4 ceiling fans installed to replace ceiling lights. The work was done rapidly, higg quality and we are very happy with the work. He quoted a full day to install them, however it did not take all day. He only charged for the time he worked, therefore was less money than quoted!! He did show up late and didn't call, but I didn't rate him down because he was so fair. I would definitely hire him again."

"We discovered a strange odor and went to investigate. We found smoke coming from a breaker in our breaker box. I called Fusion Electrical Services right away. Parker was here in two hours. He located the cause of the problem quickly, checked for any other problems, and made the the repairs. Everyone from the person who took my call to the electrician were very polite and went the extra mile to get our repair completed in a timely manner. Service was great, the price was very reasonable. I have called on Fusion Electrical Services to do the necessary wiring to install a lift in my garage and was very happy with the work. I highly recommend this company."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
