Hi,
I wanted to reply to the original comment.
It has always been my understanding that the LINE SIDE should ALWAYS be at the TOP.
I thought this was standard practice where possible? I think this carries over from the wiring arrangement in disconnects.
A feeder can enter the enclosure at any accessible place within the enclosure but should still terminate at the top. I do not think that having the line side at the bottom is good practice.
I am talking about disconnects and panelboards not switchboards, mcc or switchgear.
I know electricians that even use the top screw on switches and outlets to terminate the line.
As far as I know there is no rule that requires this but it is done. It makes practical sense and logical sense.
A GFI is usually configured the same way. Line at top load at bottom.
It seems to me there is a rule somewhere that requires the line to be at the top? Maybe I am thinking of a spec.
It may be a good idea if you want to meet the american disabilities act by that I mean having the breaker at a lower position so that a person in a wheelchair could operate the breaker.
I was on a job where some hand cut some 350 MCM feeders to the load side of a disconnect because he did not know what he was doing. If he had experience and training he would have drifted to the top anyway!
I am a top breaker guy I guess.
The photos are interesting.
Regards
Greg
