FOR APPRENTICES, INSTRUCTORS & CREWS · NEC 2023

Teach why the wires fitting isn’t enough.

Six ready-to-run exercises that separate conduit fill, ampacity derating and termination limits. A focused lesson you can print, discuss and check.

A 30-minute lesson, already prepared.

Start with a prediction. Open the stated inputs in the free checker, calculate the result, then explain which limit controls. Each exercise includes a worked answer, the arithmetic and a discussion prompt.

  1. A passing starting point: fill and allowable current
  2. Why a larger raceway can still fail ampacity
  3. The same conductors at a higher ambient temperature
  4. What the continuous-load screen changes
  5. The termination-temperature ceiling
  6. Enough ampacity, too much physical fill

The two-page sample includes one complete setup, the worked answer and the larger-raceway comparison. No email or purchase required.

Clear scope. Honest answers.

The answers are checked against numerical expectations and PassPull’s supported NEC 2023 engine. This is an educational aid, not independent electrical certification, a CE course, a complete design or an inspection guarantee.

All setups are synthetic. An instructor must verify assumptions, the adopted code and equipment. The checker’s continuous-load option is a conservative screen; it does not replace a complete branch-circuit or feeder analysis.
