Class 2 control center
(OP)
If multiple (seperately derived) class 2-control wiring enter a single "control panel" what are the code implications? Since the 120V motor controls are derived from independent sources of power, servicing the units can intoduce the potential of electrical shock.. etc/ no clear means of disconnect. Not clear to me per 2002 NEC?

One reference may be NEMA Std ICS 1-2000 Industrial Controls and Systems, General Requirements §7.5, cataloged at www.nema.org or, possibly others in the ICS 1 series.

Why argue, common sense tells you it is easier to service whatever it is regardless of the number of sources within the device.

When there are only a few, I use these, with the "pull-to-cheat" feature so that I can test circuits with the door open.
