Thomas & Betts CIFSU-1/2 – Frequently Asked Questions

1) How many conductors can I legally put in an 18.5 cubic inch FS box?
The CIFSU has 18.5 cubic inches of usable volume. Under the NEC box-fill table that supports nine 14 AWG conductors, eight 12 AWG, or seven 10 AWG before you deduct for the device, clamps, and grounds (a device counts as two conductors of the largest size present). For a single receptacle or switch with 12 AWG in and out, that leaves comfortable room.
2) Does the CIFSU box come with a cover or mounting screws?
No. The CIFSU ships as the box body only, with no screws included and no cover attachment supplied. Order the FS cover you need separately (blank, duplex receptacle, toggle switch, or GFCI) plus the gasket if the location calls for one.
3) How does the device mount in a Thomas & Betts CIFSU box?
The receptacle or switch screws directly into the box, and the box is a device connection box in the round/square FS family. It is a surface-mount style enclosure, so it fastens to the wall or structure rather than being installed inside a stud bay.
4) Does the CIFSU box clamp the conduit or does it need threaded fittings?
There is no pipe locking feature on this box, and none is offered as an option. It is a threaded-hub FS body, so conduit is threaded into the 1/2 inch or 3/4 inch hub rather than clamped.
5) Can I buy CIFSU boxes by the case for a large job?
Yes. The CIFSU is packed 20 per outer carton, which is the quantity to reference when you are laying out a full run of surface-mounted receptacle and switch points.
