## What is EdgeSpace Box Fill?

EdgeSpace Box Fill is an offline NEC 314.16 device-box volume checker for electricians and inspectors.

Pick a listed metal box (or a marked custom volume), the largest conductor AWG, and counts for conductors, device yokes, internal clamps, support fittings, and equipment grounding conductors. See required volume, box volume, fill used, PASS/FAIL, and a line-by-line 314.16(B) breakdown.

This is box fill — not conduit fill and not voltage drop.
