MV Generator Conductor Protection
MV Generator Conductor Protection
(OP)
The NEC 2014 has a MV section in Articles 2400 (IX. Overcurrent Protection over 1000V) for feeder and branch circuit conductor protection.
But it appear to me that this section can't be applied to the conductors leaving a MV Generator to the synch panel. These conductor qualify more as service conductors than feeder or branch conductors.
My question is the following:
Is there a section of the NEC 2014 that I can apply to the protection of the conductors leaving a MV generator to the service panel?
I have several local generators in parallel feeding a service panel and no utility.
Thanks.

RE: MV Generator Conductor Protection
It is not mentioned if it is about low-voltage or high-voltage, indeed.
However,in my opinion, you have to check the short-circuit current withstand.
At first of you have to calculate the short-circuit current and to state the fault clearing time.
