Steel City 4G4D B 1/2 – Frequently Asked Questions
1) How many conductors can I fill into the Steel City 4G4D B 1/2 gang box?
The 4G4D B 1/2 gang box gives you 58 cubic inches of volume, which is a lot of room compared with a standard device box, so it handles multi-device ganging and the pigtails that come with it. Work your fill from the 58 cubic inch figure and the conductor volumes required by code for the gauge you are pulling.
2) Is the Steel City 4G4D B 1/2 box a flush in-wall box or does it mount on the surface?
It is a surface mounted housing, so it sits on the face of the wall or structure rather than being set into a stud bay. If you need a box that buries in a wall cavity, this is the wrong style. Mounting direction for the device opening is horizontal.
3) Should I use a steel gang box or a non-metallic one for my switch locations?
The Steel City 4G4D B 1/2 is drawn steel and surface mounted, which suits exposed conduit work and places where the box itself needs to take abuse and carry the equipment ground through metallic raceway. If you are roughing in behind drywall on a residential or light commercial job, a non-metallic in-wall box is the easier choice. ZenSupply carries the Allied Moulded P-181 FlexBox 1-gang thermoplastic residential switch/receptacle box at 18 cubic inches, the Allied Moulded 2302-NKV fiberglass reinforced 2-gang switch box, and the Cantex EZ20SB EZ Box 1-gang non-metallic steel stud box for steel stud framing.
4) I need to add a switch to an existing finished wall. Is this Steel City gang box the right part?
No. The 4G4D B 1/2 is a surface mounted steel housing, not an old work box, so it will not clamp into a cut opening in finished drywall. For a retrofit in an existing wall, the RACO 517 TIGER GRIP gangable steel switch box is an old work box built for exactly that. If you are ganging new work and want push-in wire connections, the RACO 518S gangable switch box is 2-1/2 inches deep with a STAB-IT connector.
5) What is the difference between the Steel City 4G4D B 1/2 gang box and a RACO 517 gangable switch box?
They solve different problems. The Steel City 4G4D B 1/2 is a surface mounted drawn steel housing with 58 cubic inches of capacity, three outlets, and knockouts for conduit entry. The RACO 517 is a gangable steel switch box in the TIGER GRIP series intended for old work, meaning it is set into an existing finished wall and ganged with additional sections to build up the device count. If the wiring runs on the surface in conduit, the 4G4D B 1/2 is the form factor; if the box has to be buried in an existing wall cavity, the gangable old work box is.
6) I only need a single switch at this location - is there a smaller alternative to the Steel City 4G4D B 1/2?
Yes. The 4G4D B 1/2 is a 58 cubic inch steel housing with three outlets, which is more box than a single device needs. For one device, the Allied Moulded P-181 FlexBox is a 1-gang thermoplastic switch/receptacle box rated 18 cubic inches, and the Cantex EZ20SB EZ Box is a 1-gang non-metallic box made for steel stud framing. Both are single-gang residential-style boxes rather than surface mounted multi-outlet enclosures, so choose them only where the device count and the wiring method actually match.
7) Does the Steel City 4G4D B 1/2 box come with knockouts for conduit, or do I have to punch my own?
Knockouts are provided in the 4G4D B 1/2 box, so you can open the ones you need for your conduit or connector runs without drilling the drawn steel shell.
8) What is the exact part number to order for the Steel City four-gang drawn box?
Order it as Steel City 4G4D B 1/2. That is the manufacturer part number, and the box is a surface mounted drawn steel gang box with three outlet positions and 58 cubic inches of capacity.
9) Can I use a non-metallic box like the Allied Moulded 2302-NKV instead of the Steel City 4G4D B 1/2?
Only if the application allows a non-metallic enclosure and a smaller device count. The Allied Moulded 2302-NKV is a fiberglass reinforced 2-gang switch box, so it is non-conductive and sized for two devices. The Steel City 4G4D B 1/2 is a drawn steel housing in silver finish with 58 cubic inches, three outlets, and knockouts, and it is UL listed under E2969. Steel boxes also provide a metallic raceway path for conduit systems, which a fiberglass box does not, so the two are not interchangeable in a conduit installation.
10) Is the RACO 518S a substitute for the Steel City 4G4D B 1/2?
No. The RACO 518S is a gangable switch box 2-1/2 inches deep with a STAB-IT series connector, built for in-wall rough-in with cable entering through the integral connector. The Steel City 4G4D B 1/2 measures 19.1 by 16.8 by 7.3 inches overall, is surface mounted, and holds 58 cubic inches with three outlets and knockouts. The depth, mounting method, and capacity are all different classes of box, so the 518S will not drop into the same opening.
11) We are standardizing boxes across a steel stud build - where does the Steel City 4G4D B 1/2 fit versus the Cantex EZ20SB?
They cover separate parts of the same job. The Cantex EZ20SB EZ Box is a 1-gang non-metallic box designed to attach to steel stud framing, so it handles the individual device locations inside the wall. The Steel City 4G4D B 1/2 is a surface mounted drawn steel housing with 58 cubic inches of volume, three outlets, knockouts, and horizontal mounting, which suits exposed conduit runs and multi-device locations on finished or masonry surfaces. A typical package uses the stud box for in-wall devices and the steel gang box where wiring stays on the surface.
12) What is the Steel City 4G4D B 1/2 box made of and will it hold up in a shop or plant?
Drawn steel, silver in finish. A drawn steel body has no welded seams at the corners, which is why these get used in industrial and MRO settings where a molded box would get knocked around.
13) How do these Steel City gang boxes ship for a large job, and what do they weigh?
Standard outer quantity is 20 boxes, with a weight of 144.5 lbs per 100 boxes. The shipping carton measures 19.1 x 16.8 x 7.3 inches. Useful numbers if you are staging material by the pallet on a multi-unit or institutional job.
