Can someone please enlighten me as to the reasoning for separating neutrals in sub-panels. What are the consequences if they are left combined?
I never heard of anyone doing this. Maybe you can elaborate on what you actually mean. I suspect you actually meant to ask something other than what you did.
That is correct.I think the op is asking why the equipment grounding conductor and the neutrals are separated in a sub panel. That would be my guess.
That is correct.
my understanding--if I am reading the op correctly--is to ensure no neutral current on any EGC/GEC. If they were tied together at a sub-panel then you would have the potential for current to show up on any and all ground/bond wires--I think(?):?
Anyway that's my story and I'm sticking to it--until someone comes along and explains what I read wrong!!:slaphead:
I think that is the answer but why it would matter all that much is another thing.
This was a common install until fairly recently.
The motivation, without reading the comments around the change, would seem to be twofold:I agree---I think it was just a couple/three cycles ago they changed it
