diesel generator worked as principle of faraday's law of
electromagnetic effect.mechanical energy is converted to
electrical energy.It can stared to d.c supply i.e. 12v ,
24v.D.C supply to starter and after starting it produce
A.C. supply.Engine only use as a prime mover.

We have drive feeding an output contactor for a 5000 hp
motor @ 5kV application.
The motor FLA is 629amps x 1.25% service factor = 786.25
The cable that we current have in place between the drive
and the output contactor is 350kcmil- MV-105 (parallel
cables). Per the NEC table 310.60 (C) (69). This show the
cable ampacity is at 615 amps per cable for a rating of
We have derated the cable for the cable tray and the
multiple cables application and our calculations show that
after the correction factor factor we are at 922amps.
1230 amps x .75% correction factor factor = 922.5 amps.
The customer is driving us to then use another safety
factor of .25% off of the already derated cable. Can you
