Allied Moulded 9363-EWK – Frequently Asked Questions

1) How many wires can I get into the Allied Moulded 9363-EWK switch box?
The 9363-EWK gives you 16 cubic inches of interior volume in a 1-gang footprint. Box fill under the NEC is counted in cubic inches per conductor by wire size, so that 16 cu in figure is the number you run your fill calculation against, along with the device and any grounds or clamps. For a single switch or receptacle on 14 or 12 AWG romex it is a common residential size.
2) Can I put two devices in the Allied Moulded 9363-EWK?
No. The 9363-EWK is a 1-gang box and takes a single switch or receptacle. If you need a switch plus a receptacle, or two switches side by side, order a 2-gang box instead. Ganging is not an option here, the box is a one-piece molded enclosure.
3) Is the 9363-EWK meant for new construction or for remodel work in an existing wall?
It is a rough-in box, intended to go on the stud before the drywall goes up, for residential switch and receptacle work in new construction and in remodels where the framing is open. If you are cutting into finished drywall with no access to a stud, you need an old-work or retrofit box with wing clamps rather than this one.
4) What are the actual dimensions of the 9363-EWK 1-gang box?
It measures 2-3/8 x 3-1/4 x 2-27/32 inches. The 2-27/32 inch figure is the deep one, which is what gives you the 16 cubic inch volume in a single-gang opening. Check that against your stud depth and any insulation or vapor barrier detail before you nail it off.
5) Is a fiberglass box better than a steel box for residential rough-in?
Different tradeoffs. The 9363-EWK is molded from fiberglass reinforced thermoset polyester, so it is non-metallic and non-conductive, it will not rust in a damp wall or crawlspace, and it holds its dimensions over time. Steel is what you want when you are landing metal conduit or armored cable that needs the box for the grounding path. For romex-only residential wiring, the non-metallic box is the normal choice.
6) Will the 9363-EWK corrode in a damp basement or exterior wall cavity?
Thermoset polyester will not rust the way a steel box does, which is why it gets specified in basements, crawlspaces and humid climates. Note that this is a residential rough-in wall box, not a weatherproof enclosure. For a wet or damp location on the outside of the building you need a box and cover rated for that use.
7) What is the exact part number to order the Allied Moulded 1-gang FiberglassBox?
Order it as Allied Moulded 9363-EWK. That is the manufacturer part number, and it is the 1-gang residential switch and receptacle box in the FiberglassBox line.
