Contact
Questions, feedback and corrections all go to the same inbox, and all of them get read. Email is the one contact channel for this site — there is no form and no account.

Found a mistake?
If a calculator result, a chart value or an explanation looks wrong, the Report an Error page lists exactly what to include so the problem can be reproduced and fixed fast. Error reports jump the queue — a wrong number on a tool like this can end up sizing real equipment.
Questions about a result
If a conversion surprises you, include the values you entered (kVA or amps, voltage, single or three-phase) in your email. Nine times out of ten the puzzle is a line-to-line versus line-to-neutral mix-up or a power factor carried over from a kW calculation — the methodology page covers both, and the homepage explains the power factor point in plain language.
What I can't do by email
I can't review an installation design, size a cable run, or tell you which breaker your panel needs — those depend on your local code and a site visit, and they belong with a licensed electrician. I also can't reply to requests to add advertising, tracking or sponsored content; the site stays simple on purpose.
Response time
I read mail in batches, usually within a few days. Corrections are verified against the standards and, once confirmed, fixed in the next site update — see the editorial policy for how that works.
