B-LINE B518-3ZN – Frequently Asked Questions
1) What comes in the box with the B-Line B518-3ZN junction box?
The B518-3ZN ships as two pieces: one steel junction box with screws, plus one box cover. Nothing else is included, so any strut, fittings, conduit connectors or grounding hardware for the run come separately.
2) What size is the B-Line B518-3ZN universal junction box?
It measures 7.25 in height, 10 in length/depth and 5.5 in width, and weighs 1.62 lb. Use those three numbers to check clearance behind the strut run and in the ceiling or wall cavity before you set it.
3) Is the zinc plating on the B518-3ZN suitable for outdoor or wet locations?
The B518-3ZN is electro plated zinc over steel, which is a dry indoor interior finish. For damp, wet, or exterior work, specify a box rated for the location instead; electroplated zinc is not a corrosion finish for outdoor exposure.
4) Which part number do I order for the zinc-plated B-Line universal junction box?
Order it as B-Line B518-3ZN, an Eaton B-Line series strut electrical accessory. The 3ZN suffix is the electro plated zinc version, and it is sold as a single model with no size or finish options to pick.
5) Is this a strut-mounted box or a standard wall box?
The B518-3ZN is a universal junction box from the Eaton B-Line strut electrical accessory line, meant to work with a strut channel system rather than as a nail-on or old-work wall box. If you are wiring into stud framing or drywall, use a standard device box instead.
6) Do I need to buy a cover separately for the B518-3ZN?
No separate cover purchase. One box cover is supplied with the box along with its screws, so the enclosure can be closed out as shipped.
