In previous Parts, we looked at ways to simplify maintenance (and repair) tasks to get gains in safety and efficiency. Consider one insidious time waster that often goes undetected: the remote disconnect. The NEC requires a disconnect to be within sight of a motor, and so motors have disconnects nearby. This makes it efficient to isolate motors from their supply.
The NEC does not require local disconnects for many other applications, and consequently many designers “save money
