Bothboxes are 2-gang switches. In both boxes, all three wires in one of the 3-wire romex cables coming into the box are hot. This one needed a diagram, see below. On the box at the base of the stairs, there are three 2-wire entries, two of which go to a black/hot pigtail and white/neutral pigtail. There is a 3-wire romex for the overhead
Havea 3 way switch question about a garage I'm helping a local homeless shelter fix up. They have already installed some 3 way switches, wiring and places for 2 lights, but they aren't sure how to wire it up (the original guy who helped out isn't around anymore). Basically 2 lights in the middle of 3-way switches on either end.
Detailedwiring diagram of 3-way switches controlling more than one light are illustrated. This diagram shows connections when the power comes into the first switch, on to the second switch and then on to two or more lights switched by the 3-way circuit. Note that this configuration is easiest to do when utilizing the first method of 3-way

Actually since there are no white wires on the 3-ways, this gets simple. The black and red wires that DO go to the 3-ways are part of cables. Note which cables they are. It matters. Almost certainly, two cables are involved, and the 2 white wires in those cables are connected to each other.
Ifit was wired with knob and tube originally, it's possible that the 3 way switch was old enough to be wired as "Carter 3-way": Image from Popular Mechanics, October, 1971. In this setup, the load is switched between H-N (on), H-H (off), N-H (on), and N-N (off). Since the 3 ways have the load on the common terminal, the "travelers" can
Belowis a simple three-way schematic that can be applied to all three-way electrical light switch connections. This is only a wiring schematic and not the method used for 3-way switch installations. More three-way switch wiring diagrams depicting actual wiring methods are further down. 3-way switch schematic diagram. Theintermediate switch wiring should look like this: Do not forget to connect the Earth conductors to the Earth terminal provided. Step 5: Finally, connect the third switch, which is a two way switch, to the second length of the 3 Core&Earth cable. Connect the black wire to the L1 terminal, the grey wire to the L2 terminal and the brown wireYes The photocell is placed in series with the feed from the panel ahead of the switches. The white is the neutral, the black is the hot feed, and the red is the switched hot. Of course, this makes the circuit inoperable during the light of day and there will be no manual override. I would install an astronomical timer like this one: https
Ihave a switch box that has two 3 ways to control two different sets of lights 1 set in the hallway and 1 set in the living room and both of these sets have their own 3 way switch located in different locations but connected by 14/3 wire the power and both sets of lights are brought into the same box all with 14/2 wire.
