Allied Moulded 9338-ESK – Frequently Asked Questions

1) Can the Allied Moulded 9338-ESK ceiling box support a light fixture?
Yes. The 9338-ESK is a fixture support box, meaning it is built to carry the structural load of a ceiling-mounted light fixture rather than just house the splices. It measures 3-1/2 by 2 inches with 14 cubic inches of interior volume for the connections.
2) What is the cubic inch capacity of the Allied Moulded 9338-ESK, and how many conductors will it take?
14 cubic inches of usable interior volume. Box fill is counted per conductor, device, clamp and ground under the NEC, so work that 14 cubic inches against the conductor sizes you are landing rather than the wire count alone.
3) Is the 9338-ESK rated to hang a ceiling fan?
The 9338-ESK is described for ceiling fixture and fan mounting, so it is intended for that kind of ceiling-mounted load. Fan support has its own weight limits, so match the fan's stated weight to the box rating on the manufacturer spec sheet before hanging one.
4) Is the Allied Moulded 9338-ESK metal or plastic?
Neither exactly. It is molded from fiberglass reinforced polyester BMC, a non-metallic, non-conductive composite that will not rust or corrode the way a steel box does, and it is tougher than a standard thermoplastic box. That matters in damp ceilings, agricultural buildings and coastal work where metal boxes deteriorate.
5) Do I need a grounding conductor run to a non-metallic fiberglass ceiling box?
The fiberglass reinforced polyester body of the 9338-ESK is non-conductive, so the box itself is not part of the ground path. Any equipment grounding has to be carried through to the fixture by the equipment grounding conductor in your cable or raceway.
6) Will a 3-1/2 inch round ceiling box fit a standard fixture canopy?
The 9338-ESK has a 3-1/2 inch footprint, which is the common size range for ceiling fixture boxes, and most fixture canopies are sized to cover a box of this diameter. Check the canopy opening and your fixture's mounting strap centers against the box before you set it.
7) Is the 9338-ESK suitable for commercial ceiling work or residential only?
Both. Allied Moulded lists the 9338-ESK for residential electrical installations and light commercial ceiling wiring, in new construction and renovation alike. For heavy industrial ceiling work, check the load and environment requirements against the spec sheet first.
