If I have three bathrooms can I have all three bathroom outlets run on the same GFI located in one bathroom? Also, can all three bathroom GFI outlets be attached to the same 20-amp circuit?
Hey Matt thanks for your question. Yes, if you mean receptacle outlets. GFCI protection is required for all 125 volt single phase 15 and 20 ampere receptacles in dwelling unit bathrooms as stated in 210.8(A) but there is no limitation on using one GFCI receptacle for more than one bathroom. Keep in mind if the GFCI receptacle operates someone will need to find out where it is located. At least one 20 ampere 120 volt branch circuit must be provided for dwelling unit bathroom receptacle outlets as stated in 210.11(C)(3). The last sentence prohibits other types of outlets, such as a lighting outlet (unless the exception) is applied, on that branch circuit but one branch circuit can supply receptacle outlets in more than one bathroom.
