I recently ran into a very stupid mistake and or test. There were two thirty amp disconnects 3 phase mounted in a basement utility room for 2 commercial washing machines , nothing unusual until I looked at the back of the disconnects and they both had 3/4" pvc ran out of the back of them and no 10 wire terminated to the load side this was obviously wrong after seeing they were back to back . Where did they go? they were mounted to poured in place concrete wall. I pulled on the wires and the conduits were ran back to back between each disconnect about 8 feet apart. I see one circut for both washers nooooooooooo.My coworker said you can run circuits through the disconnects , I said no way just not a practice I have ever seen. I could not find anything in the code book , is he right? can you run a circuit through the disconnect to the next and be in compliance ?

Um......, you probably should read it, I am not seeing a violation.

312.8 Switch and Overcurrent Device Enclosures with
Splices, Taps, and Feed-Through Conductors. The wiring
space of enclosures for switches or overcurrent devices
shall be permitted for conductors feeding through, spliced,
or tapping off to other enclosures, switches, or overcurrent
devices where all of the following conditions are met:
(1) The total of all conductors installed at any cross section
of the wiring space does not exceed 40 percent of the
cross-sectional area of that space.
(2) The total area of all conductors, splices, and taps installed
at any cross section of the wiring space does not
exceed 75 percent of the cross-sectional area of that
space.
