"Jeremie and his companion did a very professional job, fixing the immediate problem, and giving us a verbal estimate of what he felt needed to be done to upgrade the basement circuits. His written estimate is to follow within a week or two. We were quite satisfied with his work."

"Nick went above and beyond to install my home car charger. He had to get through concrete in my crawlspace and installed the charger on the wall which I did not expect him to complete. The price was reasonable when compared to two other estimates. I would highly recommend First Choice."

Small jobs welcome

"Rock Electric was great. We had electricity brought to a new shop in our backyard. The Rock people were on time, they stayed in touch while we were scheduling and rescheduling. The initial visit went well and all the little details were worked out in a straightforward manner. No issues when we requested the work be permitted either. They were accommodating and professional When there was a question about the trench we dug that we thought met specs they reached out immediately and made sure they were ok to proceed. The job was done quickly and the permitting inspection was also done at the same time. Great customer service. They did a fine job of staying in touch for time frames. After initially speaking with some other outfits that never got back to us or did not show or call for their scheduled appts it was refreshing to work with a group with conscientious, communicative, customer oriented people. We would definitely hire them again if a project comes up. Thanks guys."

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

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

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
