Steel City 54151 CFB – Frequently Asked Questions
1) How much wiring volume does the 4 inch Steel City ceiling fan box give me?
15.8 cubic inches. That is the figure you count against when you tally conductors, devices, and clamps for box fill, so it governs how many circuit conductors you can legally bring into the fan outlet.
2) Will a 1/2 inch deep octagonal ceiling box fit in a shallow joist bay or against the underside of the deck?
Yes, depth is the point of this one. The 54151 CFB measures 4 inches diameter by 1/2 inch deep, so it is a shallow pan-type box for situations where there is almost no room behind the ceiling finish. The tradeoff is wiring room: at 15.8 cubic inches you are working in a tight box, so plan your splices accordingly.
3) What is the closest steel equivalent to the Steel City 54151 CFB ceiling fan box?
The RACO 295-1 is the nearest match in steel: a 4 inch round fan-rated ceiling pan from THE INSIDER series. Like the Steel City 54151 CFB, it is a steel fan-rated ceiling box at 4 inch nominal size, so it covers the same shallow-pan ceiling fan support role. The 54151 CFB is a drawn steel octagonal box with 15.8 cubic inches of volume, so compare the wire fill you need before swapping.
4) I need a non-metallic ceiling fan support box instead of the Steel City 54151 CFB. What are the options?
Three non-metallic fan and fixture support boxes cover that need. The Allied Moulded 9304 is a fiberglass reinforced ceiling fixture support box; the Allied Moulded PC244OW is the FlexBox ceiling fixture support box; and the Allied Moulded SB-CB is a polycarbonate Sliderbox ceiling fixture support box. The Steel City 54151 CFB is a drawn steel box, so the non-metallic versions differ in that grounding is handled by the conductors rather than the box body.
5) Steel or nonmetallic ceiling fan box for a retrofit, which should I use?
The Steel City 54151 CFB is drawn steel, which is what most electricians want for new work or where the box is screwed directly to framing, and it bonds through the metal itself. If you are cutting into finished drywall with no joist handy, a nonmetallic bar-type support box is easier: ZenSupply carries the Allied Moulded SB-CB Sliderbox polycarbonate ceiling fixture support box and the Allied Moulded PC244OW FlexBox for that work. The Pass & Seymour Reiker is a drop ceiling fan and fixture support box.
6) Does the Steel City octagonal fan box come with a mounting bar or brace?
It is sold as the box alone, each. If the fan location has no joist directly behind it you will need a separate fan brace or bar hanger, or step up to a box that includes its own support, such as the Allied Moulded SB-CB Sliderbox or the Allied Moulded 9304 fiberglass reinforced ceiling fixture support box.
7) Is this box acceptable for a commercial or multi-family job that requires listed electrical boxes?
The 54151 CFB carries UL E2969 and CSA 5043, so it is listed for both US and Canadian work, which is what an inspector or an institutional spec is looking for on an outlet box. Steel construction, silver finish.
8) I need more wiring room than the Steel City 54151 CFB gives me. What else should I look at?
The 54151 CFB holds 15.8 cubic inches in a 4 inch diameter by 1/2 inch deep drawn steel body, which is a shallow pan. If your fill count is tight, the Allied Moulded 9304 fiberglass reinforced ceiling fixture support box and the PC244OW FlexBox ceiling fixture support box are the deeper-bodied support boxes in the same family of applications. Confirm the cubic inch capacity you need against your conductor and device count.
