Email is the only way to reach me. Write if a result looks wrong, a source link is broken, or there’s a calculator you’d like to see.
If you’re reporting a number, tell me which calculator, what you typed in, and what you expected. That lets me check it against the sources quickly.
I can’t give advice on a specific installation or say whether your wiring will pass inspection. For that, ask a licensed electrician or your local inspector.
