B-LINE 24248 RTHC – Frequently Asked Questions

1) Can the Eaton B-Line 24248 RTHC junction box be mounted outdoors?
Yes. The 24248 RTHC carries a NEMA 3R rating, so it is built for outdoor use where falling rain, sleet and external ice formation are the concern. It also has a rain hood over the door. NEMA 3R does not cover washdown or hose-directed water, so for a pressure-wash area you want a 4 or 4X enclosure instead.
2) What are the actual dimensions of the B-Line 24248 RTHC enclosure?
It is 24 inches high, 24 inches wide and 8 inches deep. That 8 inch depth is the number to check first when you are sizing gutter space or fitting a back panel with breakers or terminal blocks behind a hinged door.
3) How does this B-Line enclosure mount to a wall, and does it come with mounting hardware?
The 24248 RTHC is a surface mount enclosure with embossed thru holes in the back. Embossed holes keep the fastener seal above the back surface, which is what preserves the 3R rating when you bolt it to a wall or strut. The mounting fasteners and anchors are sized to your substrate and are supplied separately.
4) Does this 24x24x8 junction box come with knockouts, or do I have to punch my own conduit openings?
The 24248 RTHC comes with 9 knockouts already provided, so common conduit runs land without drilling. If your conduit layout does not line up with them, the 14 gauge carbon steel body will take a hole saw or a knockout punch; seal any added opening with a rated hub or fitting to keep the 3R rating outdoors.
5) Does the B-Line 24248 RTHC door lock or accept a padlock?
There is a padlock provision on the door, so you can secure it with your own padlock. The door is a hinged, medium single door on a formed top hinge, and the cover is removable if you want to drop it off entirely while you are wiring the box.
6) What is the B-Line 24248 RTHC made of and how is it finished?
Body and door are 14 gauge carbon steel with a painted finish in ANSI 61 grey, the standard gear grey that matches most switchboards and control panels on a commercial site. Carbon steel is the right pick for general outdoor and utility work; for coastal salt air or chemical exposure you want stainless or non-metallic instead.
7) Is this B-Line junction box UL listed?
The 24248 RTHC is built to UL 50, the standard covering enclosures for electrical equipment. It is manufactured in the US.
8) What part number do I order for the 24 x 24 x 8 B-Line hinged 3R enclosure?
The Eaton B-Line catalog number is 24248 RTHC. RTHC is the hinged cover, rain hood style in the B-Line junction box line, and the leading digits give the size: 24 high, 24 wide, 8 deep.
9) How heavy is this 24x24 enclosure, and is it a one-person install?
It weighs 46.6 lb empty. That is manageable for one person to carry but awkward to hold flat against a wall while starting fasteners at 24 inches square, so plan on a second set of hands or a temporary ledger for the mounting.
