## What is Conduit Max Fill Calculator?

Three codes. One app. Works anywhere, in 28 languages.

Conduit fill for CEC (Canada), NEC (United States) and BS 7671 (United Kingdom), in one app.

Set the percentage of fill. Pick a conduit, pick your conductor, and add multiple gauges of conductors to the same conduit. The conduit resizes as conductors are added, with a visual representation of the fill.

Built by a Red Seal master electrician.

The tables are the point

Every value was taken from CEC 2024, NEC 2026 and BS 7671 2026. Checked and double checked for accuracy
