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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

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