I'm curious about which edition(s) of the NEC implemented the following:

1) Panelboards prohibited in bathrooms.
2) GFCI protection for kitchen countertop receptacles.
3) Spacing (2' rule) for kitchen countertop receptacles.

I know these were put in before I was in the game, but I figure some of the more experienced members might know.

Hey Jeff,

In reverse order:

3) The 1990 NEC shortened the distance between small appliance countertop receptacles.

2) The 1987 NEC introduced the requirement for countertop receptacle GFI protection, but it was only for receptacles within 6' of the sink. The 1996 NEC extended that to all countertop receptacles except refirs or freezers.

3) ?

Re: Historical Information

The bathroom prohibition first appeared at 240-24 (e) in the 1993 edition.

It's not exactly a prohibition against panelboards in bathrooms, it's a prohibition against branch-circuit overcurrent devices in bathrooms. Subtle distinction, eh?

Then in '96, there was as slight change in wording to it's present form to prohibit "overcurrent devices, other than supplementary overcurrent protection." What's that all about?

It is worth mentioning that only applies to dwelling unit bathrooms.

Re: Historical Information

In '93 the change was made for dwelling unit bathrooms. That dwelling unit bathrooms are not permitted to have overcurrent devices located in them. 230.24(E)
Other than dwelling units are permitted to have overcurrent devices in them, and you will commonly see this in the "gas station" complexes going up.
230.70(A)(2) does not permit services in bathrooms of any occupancy.

So you cannot put a service in any bathrooms, but you can put a panel in bathrooms of occupancies other than dwelling units.

Re: Historical Information

Thanks for all the replies. I should have clarified that I was referring to dwelling units in my original post. I work pretty much exclusively in dwelling units, so I tend to forget that other occupancies have different rules for some things.

Nah, he was just patronizing you. Bob's always been good for that. He's starting to develope a reputation.
