Steel City 72171MSXP – Frequently Asked Questions
1) How many conductors will the Steel City 72171MSXP box hold?
The 72171MSXP is a 42 cubic inch steel box, so box fill is calculated against that 42 in3 volume using the conductor volume allowances in the NEC fill tables for the wire gauge you are pulling. That is a large-capacity box by the standards of a bracket-mounted rough-in box, which is why it gets used where several circuits or a device plus splices land in one opening.
2) Does the Steel City 72171MSXP mount to a stud or between studs?
It is a bracket-mounted box. The bracket fixes it to the face or side of a stud during rough-in and sets the box depth for the finished wall, rather than clipping into an already-finished wall the way an old-work box does. If you are cutting into existing drywall with no framing access, this is not the box for that job.
3) How does cable get into the Steel City 72171MSXP box?
Cable enters through knockouts. That means you punch the openings you need on the job and add the appropriate connector or clamp for the wiring method you are running, whether that is NM cable, MC, or conduit. Connectors are not part of the box, so order them with it.
4) What does the P suffix on the Steel City 72171MSXP mean compared with a plain 72171 MSX?
The P denotes the pigtail version: the 72171MSXP is the 72171 MSX box supplied with a pigtail, so the grounding or circuit lead is already attached and you are not making that connection in the box during rough-in.
5) Is the Steel City 72171MSXP a steel box or plastic, and does that matter for grounding?
Steel. A metal box has to be bonded to the equipment grounding conductor, which is the reason the pigtail version exists. A nonmetallic box has no such requirement, so if your spec calls for a metal enclosure on the drawing, this one satisfies it.
6) Is the Steel City 72171MSXP sold individually or by the carton?
It is sold each, so quantities on an order line are individual boxes rather than a multi-pack. Useful to know when you are pricing out a rough-in count across a floor.
