Box Fill

[Jerry Coatney]

When calulating box fill do all clamps count as one conductor or do you have to figure them each ? 6 clamps = 6 conductors or 6 clamps = 1 conductor.

Welcome to the forum.

Here is what 314.16(B)(2) says;

(2) Clamp Fill. Where one or more internal cable clamps,
whether factory or field supplied, are present in the box, a
single volume allowance in accordance with Table 314.16(B)
shall be made based on the largest conductor present in the
box. No allowance shall be required for a cable connector with
its clamping mechanism outside the box.
