"Lightning Bug Electric did a wonderful job. We had Josh & Jake come out to install a ceiling fan & a new switch for it in our two story living room. They were extremely nice, funny & professional. They taught us a lot about the home’s existing wiring, & recommendations to upgrade our house that were extremely helpful. The ceiling fan came out great, & the switch as well! I highly recommend them to anyone looking to get electrical work done the right way. Incredible!!"

"We hired them last year to install a motion detector over our garage and to disconnect an outdoor junction box and wiring used by the previous owner. They did a great job and were very courteous. They were very responsive to our request and scheduled the appointment for the next day."

"Came in, got straight to work. Lights looked amazing. Only problem was they wouldn’t patch 2 small holes from removing old fixture. I took care of it no problem but it would be common courtesy to take care of that for your customer. Other than that, honestly the guys were extremely professional. He wanted to make sure my lights lined up with existing fixtures so in an event I ever changed it, it could match and looked uniformed to the ones installed. I’d definitely use them again for sure."

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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. 

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.
