Steel City 52171-CM13 – Frequently Asked Questions
1) What does the Steel City 52171-CM13 box support cover actually do on a stud wall?
It combines the box-to-stud mounting bracket and the device cover into one piece, so you mount the box to the stud and cover the device with the same part instead of installing a bracket and a cover separately. It also comes with a 10 1/2 inch insulated grounding pigtail already installed, which takes the pigtail step out of the rough-in.
2) What size conduit knockouts does the Steel City 52171-CM13 have, and where are they?
Bottom has three 1/2 inch knockouts plus two combination 1/2 inch and 3/4 inch eccentric knockouts. Each end has two 1/2 inch plus one 1/2 and 3/4 inch combination, and each side is the same, two 1/2 inch plus one 1/2 and 3/4 inch combination. That gives you 1/2 inch EMT straight in anywhere, and a 3/4 inch run out the bottom, ends, or sides without a reducer.
3) Is the Steel City 52171-CM13 UL listed?
Yes, the 52171-CM13 pre-fab box assembly carries a UL listing. Note it is not RoHS compliant, which matters if your job spec or institutional purchasing policy calls for RoHS declarations on electrical components.
4) Do I need to add a separate ground pigtail to the Steel City 52171-CM13?
No. A 10 1/2 inch insulated grounding pigtail is pre-installed, so the ground is already in the box ready to land on the device. That is the main labor saving on this assembly along with the combined bracket and cover.
