"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

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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.
