I am going to attempt to make this as clear as possible.
In my bathroom, there is a switch that directly controls only the bathroom ventilation fan. I would like to add a recessed light over the shower by adding it to the circuit that the recessed fan is on, so the connection would be switch->vent fan->shower recessed light.
Does this connection need to be GFCI protected, and if so how would I do that because there isn't an outlet in this circuit? Would the only option be a dead-front GFI?
Thanks in advance! Dan
