One setup. The checks together.
PassPull brings conduit fill, conductor-count adjustment, ambient correction, and termination limits into the same workflow. The result explains what passed, what failed, and which change to consider next.
The goal is practical: catch a mismatch while changing the plan is still easier than replacing a completed pull.
Built around the job
Use it in a browser, without an account. Save named setups on your device, share a setup link, or download a field-check record with the inputs and code references. Check again whenever the setup changes.
The core checker and its existing exports are free. An optional practice pack provides prepared exercises and worksheets for classes or crews. It is a separate one-time educational product, with a complete free sample; no calculator subscription is required.
Trust has to be earned
PassPull is the publisher of these guides. On September 26, 2026, the project owner compared the supported catalog with NEC 2023 and reported no mismatches. That catalog check is not an independent electrical certification or a review of every possible installation.
The methodology lists the table cells checked, the calculation steps, and the excluded conditions. Each worked setup in the 12 AWG EMT guide is also exercised in automated tests. Those tests check consistency with the calculator; they do not replace qualified electrical review.
