Availability of Junction Box Size for Multiple 4'' Conduit Connections

[julianov]

Hello all.

I have a question: Is there a commercially available junction box sized 36''x24''x24''? I couldn’t find one of that size in the Hoffman catalog. Why do I need this size? It’s because I need to connect 6 conduits of 4'' at the bottom, and 6 conduits of 4'' on each side (left and right), as shown in this image:

If you cannot find one in a catalog you might need to order one custom made.

Even though junction boxes are not required to be listed, a number of sheet metal shops can make a custom electrical enclosure and some are even certified to provide a listing mark on the enclosure.

Thanks. Hefti makes custom boxes, right? I believe that since the code doesn’t specify a maximum box size, we can use a custom box.

Yes they make custom boxes of just about any size and configuration.
