    A light, light switch, and outlet in our second bath is on the same 15 amp circuit that includes ceiling lights and several other outlets in two adjacent rooms. What is the best way to remove the bath electrical items from this circuit, but yet ensure that everything else remains properly connected to the circuit?

    I am doing a minor remodel on the bath, which will include the creation of a brand new 20 amp circuit that will just serve the bathroom and nothing else (new outlets, switches, lights, etc.). I am just not sure what all is involved when removing items from a circuit without interrupting everything else connected to it. Obviously, when I disconnect the bathroom switch and outlets it will effect everything else that may be connected to these items, and that is what I am not sure how to deal with. Or how an electrician would normally handle this type of project.

    Just want to get a sense of what may be involved before I consult an electrician.

    Are you taking it down to the studs? That is best so wait until then and evaluate what is needed to be done.

    The electrician will know what to do, REGARDLESS of what you think beforehand. Everything depends on how the wiring is arranged and there are MANY possibilities for that.

    You might be lucky that the bathroom is on the end of the circuit. Until you open walls or at least open all switches, outlets and ceiling light boxes, it is a guess. Most likely power is brought to the wall switches for the bathroom lights and exhaust fan, then branched off for a GFCI outlet.

    Bottom line, there's no way to know for sure until you open things up.

    Another item to consider is what size wire is currently feeding things. If it's 14g, you can't use ANY of it if you want a 20A ALL must be run in 12g.

    Turn power to the circuit off. Disconnect wires from the devices (switch, receptacle, and light fixture) and remove them from the outlet boxes. If any
    wires in the box were using the device to make a connection, maintain that connection by wirenutting the wire ends together. Cap off any bare
    wire ends with a wirenut or other terminating device. Put blank covers over the empty outlet boxes. Turn the power back on. Done.
