Steel City 54151 N – Frequently Asked Questions
1) How many conductors can I put in a Steel City 54151 N 4 inch octagon box?
The 54151 N is a 15.8 cubic inch octagon box. Under the NEC box fill allowances, that volume supports eight 14 AWG conductors (2.00 cu in each) or seven 12 AWG (2.25 cu in each) before you count clamps, devices, and grounds, each of which eats into the same total. Internal cable clamps are built into this box, and clamps count as one conductor of the largest wire size present, so plan on one deduction for them.
2) Can I hang a ceiling fan from this Steel City octagon box?
No. The 54151 N is a standard drawn steel 1/2 inch deep octagon box for outlets and splices, and nothing in its specification rates it for fan support. Ceiling fans require a box listed and marked for fan support (or a separate fan-rated brace box). Use this one for luminaires and junction work only.
3) Does the 54151 N come with cable clamps, or do I buy them separately?
Clamps are integral to the box, so for NM cable you are not buying or installing separate connectors at the box. Remember the clamps consume volume: with 15.8 cubic inches total, deduct one conductor's worth for the clamps when you do your box fill.
4) Is a drawn steel box the same as a welded one, and does it matter for my install?
Drawn means the body is formed from a single piece of steel rather than assembled from welded sections, so there are no corner seams on the 54151 N. For a maintenance crew or installer the practical difference is a clean one-piece shell at the shallow 1/2 inch depth. Material is steel throughout, finished silver.
5) What is the Steel City part number I should order for a 4 inch shallow octagon box with clamps?
Order Steel City 54151 N. That part number is the 4 inch drawn steel octagon box, 15.8 cubic inches, with 1/2 inch knockouts and integral clamps, sold individually.
