When I'm feeling thrifty.... I often hit say a master, guest, and powder room with one circuit for just the recepticals. Lighting on an adjoining room if loads allow. Anything wrong with that?

Quote
210.11(C)(3) Bathroom Branch Circuits.
In addition to the number of branch circuits required by other parts of this section, at least one 20-ampere branch circuit shall be provided to supply the bathroom receptacle outlet(s). Such circuits shall have no other outlets.
Exception: Where the 20-ampere circuit supplies a single bathroom, outlets for other equipment within the same bathroom shall be permitted to be supplied in accordance with 210.23(A).
FPN:See Examples D1(A), D1(B), D2(B), and D4(A) in Annex D.

Or have I read this wrong?
