Terms of use

Last updated September 29, 2026. By using Generator Watt Calculator you agree to these terms.

Information, not professional advice

Wattage figures on this site are typical ranges from published manufacturer charts and extension guides, not measurements of your equipment. Check the nameplate or manual for each appliance and your generator. Connecting a generator to home wiring requires a transfer switch or interlock installed to code, usually by a licensed electrician. Never run a generator indoors or in a garage.

Tools and estimates

Our calculators and lookups give estimates based on the public sources named on each page. They can be wrong for your situation, and the underlying rules and data can change. Check the original source and, where it matters, a qualified professional before you act.

Letters and templates

You may copy, edit, and use any template or checklist on this site for your own personal or household use. You may not republish our pages in bulk.

Links to other sites

We link to government agencies, courts, universities, and other outside sources. We do not control those sites and are not responsible for their content.

Advertising

The site is supported by ads served by Google. Ads are labeled. We do not endorse advertised products or services.

No warranty and limit of liability

The site is provided “as is,” without warranties of any kind. To the fullest extent allowed by law, we are not liable for any loss or damage arising from your use of the site or reliance on its content.
