Motor start/stop stations

[NEVPower]

Is there a standard or code for placement of the motor local start/stop buttons or stations.
We currently have a pump alley with a series of motors designed 20+ years ago where the start/stations were placed behind these pumps and they are difficult to reach with obstacles in the way.These pumps can be started remotely but for additional troubleshooting and maintenance operators want them relocated.

In the US, I'm not aware of any specific location requirements for pump motors. As you note, local control is not actually required at all. NEC requires a disconnecting means within sight of the motor (with exceptions), but that requirement is definitely NOT satisfied with a STOP pushbutton. If the motor controller (starter) can be locked out, then the local disconnect at the motor is not required for supervised locations.

It’s a bit if a stretch, but you COULD make a case for a push button station needing to be routinely inspected and tested, which would mean it falls under 110.26 “working space” requirements. So for example if the remote start signal fails to start it, that could be the local Stop button circuit, which means opening the local station box to test and examine the circuit, so the 110.26 space rules would apply.

Again, assuming you are in the US under NEC requirements. The CEC may be similar.
