One large neutral carried to a second location

[iwire]

OK this subject was one that I was very into a few code cycles ago.

I do not have access to my code books right now but going from memory.

Up until a few code code cycles ago there was nothing preventing us from using one large neutral for any types of circuits. There was no safety reason not to. I can think of many practical reasons not to but that is another topic.

Now some good doer put in a proposal to prevent it, likely for no better reason than it is odd.

We can still do it for column width electrical panels.

That proposal was written by one of our moderators.

I remember the discussion, parts of it anyway, and there were arguments given that basically it was a flip of the coin as to it being a good or bad practice.

Adoption of MWBC requirements and AFCI, GFCI for residential has made it an obsolete practice for most of us.

And I still feel the same way

And I still feel the same way

I do too.

The example of column width panels is an excellent one.

Purpose built equipment that implements exactly what I am arguing should be allowed since it is neither unsafe nor unsound if sized and identified correctly.

As also pointed out, the NEC is the rule and I will follow it but the rule is - as Col Potter would say - horse hockey.

This pretty well sums it up. Not so much the practice of the extended Neutral itself, rather all of the other rules that no longer make it practical.
