Estimates

Results depend on the values you enter and the limited model shown on each page. They are planning aids, not supplier quotations or certified measurements. Actual requirements vary with product, installation and site conditions.

Scope

The site does not certify structural designs, conductor ampacity, electrical protection, chemical ratios or safe installation practices. A wire gauge comparison concerns voltage drop only. Follow the applicable product instructions and obtain professional advice when your project requires it.

Reporting problems

Use the report form if an answer appears wrong. The site is provided as available without a guarantee of suitability for a particular project, to the extent permitted by applicable law.
