DESIGN QUESTION
(OP)
I have designed a AC cabinet with a transformer of 2 kva inside. 208/120. The secondary side neutral is grounded and bonded as this is seperately derived system. The feed from the transformer leaves the cabinet and goes to another cabinet to distribute the 120v power. The ground wire is also taken in the 3 wire system (P,N,G). Is it required to ground the neutral again in this new cabinet? What will happen if I ground again ? is there any violation of code if do ?
thanks
thanks

To help you wend your way through the code:
Just remember that as soon as you ground the N in a second location the G will automatically be sharing the N current! This is always; bad, bad, BAD!
