Allied Moulded P-352OW – Frequently Asked Questions

1) Will the Allied Moulded P-352OW hold three devices, and how much wire fill does it allow?
The P-352OW is a 3-gang box with 55 cubic inches of interior volume, so it takes three switches, three duplex receptacles, or any mix of the two plus the conductors, connectors and grounds that come with them. That volume is the number you run your box fill calculation against when you are feeding a three-device run.
2) Is the P-352OW plastic or metal, and does it need grounding?
It is a thermoplastic box, non-conductive and corrosion resistant, so the box itself is not part of the grounding path the way a steel box is. Your equipment grounding conductors get joined inside the box and carried to each device. That also makes it lighter to handle on a long run of rough-in than a three-gang steel box.
3) Can I use the P-352OW FlexBox on a light commercial job or is it residential only?
Allied Moulded lists the FlexBox line for residential and light commercial interior wiring, and the P-352OW specifically for residential new construction, multi-device receptacle and switch banks, remodel work and light commercial interiors. For heavy commercial or industrial work where raceway and metallic boxes are specified on the drawings, this is not the box to bid.
4) Is the P-352OW big enough for three devices plus a stack of wire nuts, or should I step up in volume?
55 cubic inches across three gangs works out to roughly 18 cubic inches per device position, which is generous for a typical 14 or 12 AWG three-device bank once you count the device allowances, grounds and a set of connectors. If you are landing multiple home runs and travelers in the same box, run the fill math before you commit, because the device allowance eats volume fast.
5) What part number do I order for the Allied Moulded 3-gang 55 cubic inch FlexBox?
Order it as Allied Moulded P-352OW. That single catalogue number covers the 3-gang, 55 cubic inch thermoplastic FlexBox; there are no finish or size options to specify with it.
6) Where can I get the manufacturer spec sheet for the Allied Moulded P-352OW?
Allied Moulded publishes a PDF spec sheet for the P-352OW, hosted at media.distributordatasolutions.com under the alliedmoulded document library. It is the document to hand an inspector or attach to a submittal package when the box needs to be shown on the job's product list.
