The unfortunate part when presented with such misleading questions is we seldom are afforded an opportunity to rewrite them to suit our disposition at the time... :blink:
 
In vetting some exam questions....

4/0 AL 75* conductors on the secondary of a 208Y transformer. What is the maximum OCPD allowed?
The author says it is 200 amp. I say this should be max 175 per 240.21(C).
What say all?


I agree with you on this also .
