"Great company to work with. Wonderful staff and clear explanations every step of the way. Did everything they said they would do when they said they would do it. Very tidy and no mess despite having to excavate to put in the oil tank for the generator. Installation was done quickly and efficiently. Two years later all working very well and good annual service agreement. Would absolutely work with this company again and recommend them to anyone."

"Outstanding service. Less than one week from initial contact to completion of the job. Everything done in a professionally, neatly, and to code. No cutting of corners. Fair pricing and relatively quick (about 4.5 hours in total from beginning to end). They even went the extra mile and installed my 3rd party charger and tested it on the car. I'm very pleased and will be happy to call T&G again when I need electrical work done."

"I hired Chris to install a ceiling fan with remote and move the existing light fixture to another room. He and his colleague were professional and did a great job. Old house required some trouble shooting with the fan switch/remote and Chris proved to be a good problem solver. Minor scheduling issues, but that's to be expected when contractors are trying to squeeze in a small job. Overall, very happy with the work and Chris' responsiveness; definitely recommend him to others and I will use him again."

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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. 

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.
