Running motor branch circuits thru adjacent starters

[Isaiah]

The field mounted two combination motor starters side by side on the wall and used one of the starters as a wire way to run the motor branch circuit to the adjacent one. They used a close nipple to connect the two.
Is this a violation?

That information alone is not enough to say it is a violation.

First thing is if it is a combination starter with OCPD as the disconnecting means you technically have two branch circuits supplied by one feeder, and that is not a violation.

If you do truly have one branch circuit then next thing you need to ask is does each motor have proper short circuit and ground fault protection? This can be possible with smaller motors but not as likely with larger motors, unless they never run simultaneously.

Not that I'm aware of. I believe only service conductors have such a restriction.

These are for small 460V motors. There are two separate motor branch circuits routed from a 480V 3ph 3w power panel with one, 1” conduit carrying both 3ph branch circuits to the first starter enclosure, which connects to the other immediately next to it-i.e. within a couple inches.

Seemed to have misread another OP, (maybe should get off the computer and go to work) nothing wrong with what was said unless maybe service conductors are involved.
