  1. Dave Rongey says:

    Hi Barry,
    The primary power source would be spliced so it may provide power to the new switches and then to the GFCI outlet. However if the bathroom already has an outlet then the additional GFCI should be fed from the existing outlet.
    Be sure that the existing circuit has the capacity for the additional loads.
    I hope this helps,
    Dave

    I currently have a single switch in an unfinished bathroom that has power to it. The switch controls a single light in the middle of the room. I’m finishing off this bath and I want to tap into this power feed and expand to four switches that individually control three separate lights and an exhaust fan. Also, I need to feed a GCFI outlet dead-ended by the sink. How do I wire this gang of four individual switches and one outlet arrangement? Thanks for your help!
