Terms of use

Outage Sizer provides general information: figures quoted from the public sources named on each page, and calculations made from them. It is not professional advice. Never run a generator indoors or in a garage, keep it at least 20 feet from doors, windows and vents, and connect it to house wiring only through a transfer switch installed by a qualified electrician.

Sources can change after the check date shown on a page; the source's current version governs. Content is provided "as is" without warranty. To the extent permitted by law, Outage Sizer is not liable for losses arising from reliance on the site. Trademarks belong to their owners and are used only to identify the products and standards discussed.
