Electrical Wiring in the Home/3 way hall light with ft porch light
I have 2 switches on the wall inside my front door. One switch controls the ft. porch light outside, the other switch controls the foyer lights, which is a 3 way and can be turned on from the kitchen too. there are (3) separate wires inside the box- they are: (2) 14/3 w/ground, and a 14/2 with ground. only one wire is hot inside the box- a black on one 14/3.
I changed the switch and tried to install designer switches. Ft. porch light doesnt work now .I guess its a type of 3-way circuit with a line for the ft. porch?
Professional electrical wiring never involves guesswork.
The most likely scenario is that the 3-wire with the hot black goes to the foyer light, where the hot comes from the kitchen switch box or a receptacle.
That black is supposed to feed both switches. Were there splices you took apart?
With those wires, the way I would have used them would be:
3-wire from foyer light
Black- hot feed to front switch box connected to white of other 3-wire for 3-way (to carry feed to other switch) with black tail to feed single-pole for front door
White neutral for front door light
Red to 3-way switch common to control foyer light
White hot, black and red travelers
White neutral to white of foyer light 3-wire
Black to load side of single pole switch.
Built about 3, 000 houses wired that way
