B-LINE 18186 RTSCGV – Frequently Asked Questions

1) Can the B-Line 18186 RTSCGV junction box be used outdoors?
Yes, within the limits of a NEMA 3R rating. The 18186 RTSCGV is a Type 3R galvanized steel enclosure with a rainhood over the cover, so it handles falling rain, sleet and external ice formation on an outdoor wall. It is not a washdown or hosedown box, so if the location gets pressure washing or heavy wind-driven water you want a Type 4 instead.
2) Is the B-Line 18186 RTSCGV a UL listed enclosure for a job that specs it?
The enclosure is built to UL 50, the standard for enclosures for electrical equipment, and is rated NEMA Type 3R. If your drawing calls for a UL 50, Type 3R screw-cover steel junction box, that is what this is. It is made in the US if the spec carries a domestic sourcing requirement.
3) Does this B-Line enclosure come with conduit knockouts already punched?
It has 9 knockouts in the bottom only. The sides, top and back come blank, which is what you want on a 3R box, since a top penetration is the fastest way to lose the rain rating. If your conduit runs enter from the side, you will be punching your own holes and sealing them with a rated hub or fitting.
4) What do I need to mount the B-Line 18186 RTSCGV to a wall?
The back has embossed thru holes for surface mounting, so you fasten directly through the back of the box into the wall. Anchors or lags are not supplied and are sized to your substrate. The box weighs 18.2 lb empty, so on stud or block figure your fasteners for that plus conductors and any back panel.
5) How does the cover attach, and does that matter for a box I need to get into regularly?
It is a screw cover with plated screws, not a hinged or latched door. Fine for a pull box or a termination point you open once at rough-in and maybe once a year. If maintenance staff are in it monthly, a hinged-cover enclosure is less trouble, because screw covers get dropped, cross-threaded, and left off.
6) Is this B-Line junction box painted, and will it corrode outdoors?
Unfinished galvanized steel, grey in appearance, with no paint topcoat. The zinc coating is the corrosion protection. That is standard for exterior utility and service locations. Coastal salt air or chemical exposure calls for stainless or a polycarbonate enclosure instead, and if you need a specific color it has to be field painted.
7) What is the exact part number to order this B-Line box, and what does the RTSCGV designation mean?
Order it as Eaton B-Line 18186 RTSCGV. The leading numbers are the box size, 18 high by 18 wide by 6 deep, and RTSCGV identifies the rainhood screw-cover galvanized configuration. Quote both together, because B-Line uses the same size digits across several cover and rating styles.
8) Can I mount a back panel or terminal blocks inside this enclosure?
Nothing internal is included. The 18186 RTSCGV is a medium single-door screw-cover shell with a bottom knockout pattern, no panel, no DIN rail, no terminal strips. Back panels and mounting kits for B-Line enclosures are ordered separately and sized to the 18 x 18 interior.
9) What gauge steel is the B-Line RTSCGV enclosure, and is that heavy enough for a commercial install?
16 gauge galvanized steel walls. That is the usual body thickness for commercial sheet steel enclosures in this size class, stiff enough that an 18 x 18 face will not oil-can when you tighten the cover screws or drill for hubs.
