B-LINE 1286 RTHC – Frequently Asked Questions

1) Can the B-Line 1286 RTHC junction box be mounted outdoors?
Yes. The 1286 RTHC carries a NEMA 3R rating, which covers outdoor use against falling rain, sleet and snow, and it includes a rain hood over the door. It is not a washdown or hosedown enclosure, so keep it off locations that see direct spray or submersion.
2) What are the box dimensions on the B-Line 1286 RTHC enclosure?
12 inches high, 8 inches wide and 6 inches deep, in 16 gauge carbon steel. Lay out your device plate and conduit runs against that 6 inch depth before you commit, since deep breakers or large wire bends eat it fast.
3) Does this B-Line enclosure come with conduit openings already punched?
It ships with 4 knockouts, so you are not drilling the primary conduit entries. Any additional entries you punch yourself should be made in the sides or bottom to keep the 3R rating intact.
4) How does the 1286 RTHC mount to a wall or strut?
Surface mount, through embossed thru holes in the back of the box. The embossing stands the hole off the mounting surface so water does not track into the enclosure at the fastener. Fasteners and any strut hardware are supplied by the installer.
5) Can the door on this B-Line junction box be padlocked?
Yes, the single door has a padlock provision. The cover is hinged at a formed top hinge and is removable, so a tech can swing it open for service or take it off entirely during rough-in and still lock it out once energized.
6) Should I use a hinged cover enclosure like this or a screw cover junction box?
Pick the hinged version when someone will be opening the box regularly, for splices you re-enter, terminal blocks, or a control device. The 1286 RTHC swings on a formed top hinge and the cover is also removable. A screw cover box is the cheaper choice for a run you close up once and never touch, but on an outdoor 3R location a hinged door with a rain hood is far easier to service in the weather without dropping hardware in the mud.
7) What part number do I order for the 12 x 8 x 6 B-Line 3R hinged enclosure?
Order Eaton B-Line model 1286 RTHC. The number reads out of the dimensions: 12 inch height, 8 inch width, 6 inch depth, RTHC for the rain-hood hinged cover style.
8) What color and finish is the B-Line RTHC enclosure, and will it match our existing panels?
Painted ANSI 61 grey, the standard gray used across most industrial control and distribution gear, so it blends with existing panel lineups rather than standing out.
9) How much does the 1286 RTHC weigh, and can one person hang it?
7.8 lb empty, so a single installer can hold it up and set the fasteners without a helper. Load the wall anchors for the weight of the box plus whatever devices and conduit you land in it.
