- Electricians and people planning wire pulls
- Worth noticing
- For mixed wire sizes, it sums area directly; the 0.8 rounding rule applies only when every wire is the same size.
Field notes
The input controls cover conductor quantity, gauge, insulation, and color alongside conduit material and trade size. The explanation identifies NEC table sources and separates the rules for one, two, and three-or-more conductors; it also calls out the 24-inch-or-shorter nipple exception. The page advises readers to check local code and their inspector.
