"Excellent job installing our 120V outdoor generator outlet! The weatherproof box is securely mounted, ran the conduit neatly, and clearly labelled for emergency use. I truly appreciate the quick turnaround time and how efficient you got everything set up and tested. Highly recommend for any fast reliable electrical work!"

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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

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.

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

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