I did a search and couldn't locate this topic--I'm pretty sure it's been discussed before. Pointers to an existing thread is great if someone has it. Otherwise--

1) What was the purpose/substantiation for not having a service disco in a bathroom?

2) Does anything prohibit passing 'through' a bathroom to gain access to the service disco?

3) (Lets get real silly)--Can the working clearance for the service disco be in the bathroom, while the service disco itself is actually out of the bathroom? e.g. closet door.

I work commercial... even so...

1) Too wet.

2) That's one weird bathroom layout. I wouldn't dream of it since no fireman would ever think to look there when time is critical.

3) Too wet.

More generally, a SERVICE disconnecting means is a critical piece of safety gear and is not to be shoe-horned in to a home.

This is the last item one should think about scrimping on.

Out my way, most SERVICE disconnects will be outside: NEMA3R, even in snow country. When needed, a 'bird house' is set. (micro-roof)

If I were to run into cramped quarters... I'd put the disco outside. It'd usually be quicker, too.

As for the history of various Code provisions... I don't have the interest or the time.

Reading the ROP to the 1996 where this came from, I say no to both ideas.

4-112- (230-70(a)): Accept
Note: It was the action of the Technical Correlating Committee
that this Proposal be referred to Code-Making Panels 1, 2, and 10 for
SUBMIT'rER: Raymond E. Harper, Seattle, WA
RECOMMENDATION: A new paragraph be added to Section 230-
70(a) to read:
Service disconnecting means shall not be installed in the bathrooms.
A bathroom shall be as defined in Section 210-8.
SUBSTANTIATION: Many bathrooms are not readily accessible
when occupied and the door locked. Servicing the unprotected
conductors in such a confined space with the grounded plumbing
fixtures could be hazardous. This is not a proper location for a
service disconnect. This would be in accord with Section 240-24(e).
PANEL STATEMENT: The Panel recommends that the Correlating
Committee review this based on the actions of Panel 10 under
Section 240-24(e)

All of this stuff is available on the NFPA web site these days.

Go down and change the "edition to display" to the cycle you want to look at.

Greg, Thanks. I was looking for that link on NFPA too. Very helpful. I had recalled some language regarding 'access' to the bathroom vs. the damp or wet location substantiation. The 'access' substantiation is more helpful in dealing with the question about passing through the bathroom.

People come up with all kinds of creative ways to layout their basements.
