Corrections to calculations

If you think a result is wrong, please tell us. Include the calculator name, the inputs you used, the result you expected, and the source you based that on, such as a table edition, a manufacturer datasheet, or a code section. We check every report and will update the tool and note the change where it matters.

Other questions

For general questions about how a tool works, what a field means, or what the site is for, email us with a short description of what you were trying to do. We cannot give personal electrical advice or inspect your wiring, so for an installation question on a real circuit, please contact a licensed electrician.
