Carlon E1212C24 – Frequently Asked Questions

1) Is the Carlon E1212C24 junction box rated for outdoor use?
Yes. The Carlon E1212C24 non-metallic junction box assembly carries NEMA 1, 2, 3, 3R, 3S, 4, 4X, 12 and 13 ratings, so it holds up outdoors against rain, sleet and hose-directed water, and 4X adds corrosion resistance. That combination is what makes it usable on an exterior wall, in a wash-down area, or in a coastal or chemical environment where a steel box would rust out.
2) Will a 12x12x4 non-metallic junction box give me enough room to splice a zone lighting circuit?
That is the application Carlon lists for the E1212C24. At 12 x 12 x 4 inches the box is sized to hold the splices for zone lighting takeoffs or to gang multiple circuits together so you can cut down the number of home runs back to the panel. It is a splice and consolidation box, not a box with devices or breakers in it.
3) Is the Carlon 12x12x4 junction box UL listed for a commercial job?
Yes, it is UL listed under file E88685. That is the number an inspector or a spec reviewer will want to see for a general purpose electrical enclosure, and it is what lets the box go in on commercial and institutional work where listed equipment is required.
4) Does the Carlon E1212C24 junction box come with the cover, or do I order the lid separately?
It ships as an assembly, box and curved lid together, under the single part number E1212C24. No separate cover order is needed. What is not included is conduit hubs or fittings: the enclosure has no factory knockouts called out, so the openings you need get made in the field with the appropriate fittings to keep the NEMA 4X seal intact.
5) Should I use a non-metallic junction box or a steel one for an outdoor splice?
Non-metallic is the choice where corrosion is the risk: parking structures, coastal sites, car washes, food plants, water treatment, anywhere a painted steel box eventually blisters and streaks. The Carlon E1212C24 is non-metallic and carries a 4X rating, which is the corrosion-resistant rating. Steel still wins where you need physical impact resistance from vehicles or equipment, or where the box has to serve as an equipment grounding path. A non-metallic enclosure does not bond anything, so the ground has to be carried through on the wire.
6) Can I mount a Carlon 12x12x4 non-metallic box in a dusty industrial area or a machine shop?
Yes. The E1212C24 assembly is rated NEMA 12 and 13 in addition to its outdoor ratings, which covers circulating dust, lint, falling dirt and dripping non-corrosive liquids, and 13 covers oil and coolant spray. That is the range you want for a plant floor or a shop where coolant mist and metal dust are in the air.
7) Is the Carlon E1212C24 a junction box or an electrical panel enclosure?
It is a general purpose splice and pull enclosure, not a panel. There is no interior mounting pan, breaker provision or device space called out for it. Use it to land, splice and redistribute conductors, for zone lighting takeoffs, multi-circuit distribution points, and pulling long runs. If you need to mount controls or terminal blocks inside, look for an enclosure that specifies a back panel.
8) Is the Carlon E1212C24 enclosure made in the USA?
Yes, country of origin is the United States. On public and federally funded work where domestic sourcing has to be documented, that plus the UL E88685 listing is usually what the submittal needs on a general purpose enclosure.
9) What does the curved lid on the Carlon junction box do?
The curved cover sheds water rather than letting it pool on top, which matters on an exterior vertical or upward-facing mount where a flat lid collects rain and debris right over the gasket line. It is part of how the assembly holds its 4X and 3R ratings in weather.
