"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

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
