"Kyle, the owner of Canyon Electric, was recommended to us as a trustworthy electrician in the Black Hills area. We had purchased a vacation home in Lead and were having a hot tub and sauna installed. We needed to add 2 240 amp breakers, a new breaker box, and hard wiring both units. We are from across the state and had a deadline for the hot tub installation, which required all wiring done very specifically and in place. Kyle was out at our home wiring and prepping before we even arrived. He was in contact with our hot tub retailer and made sure everything was done perfectly. The wiring on both units was done efficiently. He even did work on one of our bathroom exhaust fans and had it going in quick order. Kyle was a very pleasant person to deal with and we were very impressed with the high standards of his work. We would highly recommend Canyon Electric for any and all of your electrical needs."

Generator Install FAQs, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.
