Terms of Use

Last updated: 25 August 2026.

No professional advice

Every calculator on this site produces an engineering estimate based on simplified, general-purpose reference tables and formulas. It is provided for informational and planning purposes only and is not a substitute for advice from a licensed electrician or engineer, or for verification against your local electrical code (NEC, IEC 60364, BS 7671, or your national equivalent).

No warranty

Results are provided "as is," without warranty of any kind. We work to keep the underlying reference data accurate and welcome corrections (see contact), but we cannot guarantee that every result is correct or fit for a specific real-world installation.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from reliance on a calculator result on this site.

Changes

We may update these terms from time to time; continued use of the site after a change constitutes acceptance of the updated terms.
