We read every message. Please allow a few business days for a reply.
Report a possible error
Corrections make the calculator better. Include:
- the inputs you entered (or attach the printed planning report),
- the result you saw and what you expected,
- the source or datasheet that supports your expectation, if any.
Safety-related reports are prioritised. Confirmed corrections are versioned and listed on the Methodology page.
What we can’t help with by email
We can’t review your specific installation, choose wire or fuse sizes, or approve a design. For that, contact a qualified electrician or marine electrical technician in your area.
Emergency? If equipment is smoking, swelling, unusually hot or on fire, move to safety and contact local emergency services. Don’t wait for an email reply.
