I'm hoping I can explain this without pictures right now....
Any electricians out there please let me know if I'm on the right track here...
Ran new 12/2 cable from circuit box to bathroom, securing to all but a few ceiling joists. Cable comes in and enters a single-gang box that will house a GFCI duplex outlet.
Another section of 12/2 exits the box from the bottom then over to a 3-gang box that will house the switches.
That wire will connect to the first switch which will feed the 2nd and that one the 3rd.
I have a 12/2 cable coming in from 2 recessed fixtures above shower (vapor proof) which will be controlled by a dimmer in the box.
I have another 12/2 coming in for the vanity light to a switch.
I have a 12/3 wire coming in from the vent fan / light combo. One will hook to a regular switch, one to a time switch.
I would assume that I would connect all neutral wires together in this box?
I would also connect all the grounds together in this box.
(by the way if you add it up it comes to 4, I have a Lutron switch that is a dimmer on top with a timer on bottom for one gang)
Is there a simpler way of hooking all this up without having all those wires in a 3-gang box?
If you need further clarification I will try to put together a diagram of how everything is run.
Lastly, is it a good idea to run everything off the GFCI outlet? I'm thinking if the thing trips you'll be without all light in the bathroom but I think the protection is good.
