Terms of Use

Last updated: July 1, 2026

By using ElectricalToolbox, you agree to the following terms.

Reference only, not code compliance

Results are for reference only. Verify against the applicable adopted edition of the NEC and consult a licensed electrician for code compliance. Calculators on this site implement the formulas and tables cited on each tool's page, but the NEC edition adopted in your jurisdiction may differ, and local amendments can change requirements. Nothing on this site is a substitute for a licensed electrician's judgment on an actual job.

No warranty

This site is provided free of charge, "as is," without warranty of any kind, express or implied, including but not limited to accuracy, fitness for a particular purpose, or non-infringement. Use of any result is at your own risk.

Acceptable use

Don't attempt to disrupt, scrape at abusive volume, or circumvent the normal operation of this site. The calculators and content are free to use for personal and professional work; wholesale reproduction of the site's content elsewhere is not permitted without permission.

Changes

These terms may be updated as the site changes. Continued use after an update means you accept the revised terms.
