I'm finishing my basement and trying to do everything by the book for
the obvious safety/liability reasons. I have read some previous posts
regarding bathroom circuits, and I think I understand what I can and
can't do wrt '96 NEC.
However, I haven't found any threads on the subject since the '02 NEC
release, and I want to make sure I'm going to be in compliance. Since
the thought of reading the actual document gives me the willies, I
decided to see if there are any electricians lurking who would
I'm planning on running one 20-amp circuit for 2 bathroom outlets and
the fan. Wire from the breaker to a GFCI outlet, then to another
outlet, then to the switch, and on up to the fan. I'm planning on
wiring the bathroom lights on a different 20-amp circuit (the adjacent
bedroom). Is this up to '02 NEC code?
Many thanks to all who take the time to reply!
As far as I can tell, it sounds legal and safe, but I'm no electrician.
However, I'd rather not put the fan onto GFI-protected segment of the
circuit for convenience reasons. The more junk you add, the more likely to
trip, and you don't gain in safety unless exhaust fan happens to be inside
shower or bathtub enclosure. I'd GFI protect just the two bathroom
(BTW, in my town you can DIY with a permit and inspection, which should
eliminate safety/liability issues.)
As long as the circuit goes to just one bathroom, you can put lights and
fans on the outlet circuit; but why would you want to? As long as you are
running two circuits to the bathroom, why not put the fan on the lighting
circuit? If not that, then at least take it from the first outlet before
You didn't ask about the bedroom. Is it new? If so, you will need an AFCI
breaker for it. Even if it isn't new, the fact that you are extending the
circuit might require one.
I was thinking of putting the fan directly above the shower, and I
thought that it needed to be GFCI protected. But I may keep it
outside of the shower, in which case I would probably wire it
separately from the GFCI.
It sounds like I should have been asking about the bedroom. :)
I am actually putting in 2 bedrooms, 1 bath, and a family room (with
wet bar). I am tentatively planning the following circuits, all new:
1. Bath outlets (20A, GFCI)
2. Bedroom 1 outlets, lights, bath light (20A)
3. Bedroom 2 outlets, lights (20A)
4. Family room lights 1 (15A)
5. Family room lights 2 (15A)
6. Family room outlets 1 (20A)
7. Family room outlets 2 (20A)
8. Wet bar outlets (20A, GFCI)
So it sounds like I need AFCI breakers for circuits 2 and 3. Are AFCI
breakers required for any of the other circuits?
I am also considering a small refrigerator (maybe 3'-4' high) and
small microwave in the wet bar area. Do either or both of these need
to be on separate circuits?
