"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"Advanced generator systems did an amazing job installing a whole house generator. They were extremely polite, knowledgeable, professional, and courteous. They went above and beyond by explaining all aspects of the functions of the generator. They were extremely clean as well. You would not have even known they were there. They started in the AM and the generator was running by the end of the day! Andâ ¦their pricing was amazing. This is a company you should hire!!"

Generator Install questions, answered by experts

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. 

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.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
