Equipment & SystemsQuestion 320 of 521
A generator disconnecting means must be capable of doing what?
a.It is optional for standby units
b.Only opening the neutral conductor
c.Disconnecting the generator and all protective devices and control apparatus, and be lockable in the open position
d.Serving as a plug and receptacle only
Explanation
Section 445.18 requires a disconnecting means that shuts down the generator, disconnects it and all protective devices and control apparatus from the load, and can be locked in the open position. Opening only the neutral or relying on a cord-and-plug connection does not satisfy the full disconnect and lockout requirement.
