FIG. 00 — IN PROGRESS
CONDUIT SIZE CALCULATOR
Given a list of conductors with mixed gauges and insulations, this calculator will recommend the smallest NEC-compliant conduit trade size for each supported conduit type.
⚠ STATUS · TOOL UNDER FINAL VALIDATION
We're finalizing this calculator's NEC validation. In the meantime, use the conduit fill calculator and the wire fill chart on the homepage.

WHAT THIS TOOL WILL CALCULATE
- 01Input: list of conductor rows (gauge + insulation + count) — same model as the conduit fill calculator.
- 02Output: smallest EMT, IMC, RMC, PVC Sch 40, PVC Sch 80, FMC, LFNC, and ENT that fits the conductor mix.
- 03NEC fill rule applied automatically (53/31/40 by conductor count).
- 04Side-by-side comparison so you can choose by material cost or installation type.
