Affiliate disclosure

OutageCalc is free to use. To pay for it, some links to stores and brands are affiliate links. When you click one and buy something, we may earn a commission. You pay the same price.

Commissions never change the calculator. The sizes it recommends come only from the formulas on our method page, and we list products from several brands that meet those sizes.

As an Amazon Associate we earn from qualifying purchases.
