Corrections with sources get fixed first. Response target: five business days.
What to send
- Corrections: page URL, the exact number or sentence that is wrong, the correct value, and its source (NEC article, table, or manufacturer sheet). Reports with a source get fixed first.
- Broken calculators: calculator name, the exact inputs entered, what you expected, what you got, and which NEC rule you checked it against.
- New tool requests: the sizing question in one sentence, the NEC article behind it, and how often the question comes up in your work. Requests backed by search demand and a citable rule get built first.
- Partnerships: who you are, what you do, and what you propose, in a few sentences. This site does not run paid placements; proposals should respect that boundary.
What happens next
Every message is read. Verified errors in calculators or content are corrected and the correction is noted on the page. Tool suggestions are logged against search demand and built when the evidence supports them. Response targets: corrections within five business days; everything else as capacity allows. Please do not send account passwords or client personal information.
