Email is the way to reach JobWireCalc. There is no account and no message form on this site.
Use that address for a wrong result, a missing limit, or a question about the site. Include the tool name and the inputs you typed so the arithmetic can be checked. JobWireCalc is published by Haimc. A shorter vanity domain may be added later. It is optional, and these calculators do not depend on it.
JobWireCalc does not offer design review, permit advice, or an official code interpretation. For a ruling on a job, ask the authority having jurisdiction.
