Pass & Seymour BOX52 – Frequently Asked Questions

1) Does the BOX52 come with a bushing, or do I need to order one separately?
An insulated bushing is included with the BOX52. It protects the conductors from the sharp edge at the knockout and adds insulation where the cable enters the box, so nothing extra is required for that part of the install.
2) Is the Pass & Seymour BOX52 grip approved for use in Canada as well as the US?
Both. The BOX52 carries UL and CSA listings, which covers inspections on either side of the border for commercial and industrial electrical work.
3) Will the BOX52 strain relief grip fit inside a crowded control panel?
Its footprint is 0.75 in x 0.73 in, which is small enough for tight enclosures, power boxes and control panels where knockouts sit close together.
4) Is BOX52 the actual manufacturer part number to order from Pass & Seymour?
Yes, BOX52 is the Pass & Seymour manufacturer part number for this strain relief grip with insulated bushing, and it is sold as a single model with no finish or size options to specify.
5) What kind of jobs is the BOX52 strain relief grip meant for?
It is aimed at enclosures and junction boxes, power distribution centers, machine tool wiring, industrial control panels, commercial power boxes and manufacturing equipment. Typical work for an MRO crew or a contractor terminating flexible cable into fixed equipment.
