Our customer's (major automotive manufacturer) local safety
standard states the following requirement to main power
disconnect switch: " OPERATING HANDLE SHALL BE PERMANENTLY
AFFIXED TO THE DISCONNECT SO THE HANDLE IS IN CONTROL OF THE
DISCONNECT AT ALL TIMES, INCLUDING WHEN THE ENCLOSURE DOOR
IS OPEN". Was this requirement originated from any of more
general standards (like National El.Safety Code or NFPA) or
this is just local initiative?
