How do you wire a light and switch with the 2 wire old romex?
with a standard 1 pole light switch (one switch operating the light) it is black wire to black wire and white to white (non grounded)
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
Have 3 lights Power to light 1 Need to connect light 2 then light 3 then down to single pole switch How do you wire?
You would wire the switch to the first light. Code says to break the black or power side of the circuit. Connect the white to the light. Take the black down to the switch on the black wire and back to the light on the white. This is a line of wire from the light to the switch. From the first light, take the white and the return white from the switch to the second with another run of wire. This will be regular black white with ground. White to white and at the first light the return line from the switch is white but hook to the black to the second light. Second light to third just continues the two wires. Black to black, white to white. I think this is clear enough to follow. If not, ask again.
New ceiling fixture goes on as soon as power is back even though switch is off?
You switched the power and switch wires. There should be two sets of wires in the ceiling box. 2 black, 2 white, 2 bare. Two groups of three. The white wire going to the light is the incoming wire. The black one in that group is the power coming in. Take that black wire and connect it to the other black wire. The second black wire goes to the switch. The power comes back to the light on the white wire of that set. Connect that white wire to the black wire in the fixture. The switch should work now. That is if everyone wired the house the way it is supposed to be.
White wire a black wire a red wire and a bare wire?
white wire = neutral bare wire = ground black wire = line voltage red wire = returned from a switch, or the other phase of line voltage in order to supply 240VAC

When at a 2 pole light switch and the wire colors shown are black white and green which is the hot wire and which is the common?
the black wire is the hot wire

Which electrical wire to cut black or white?
Black is hot and white is neutral. If you are switching something you switch the black, so that is what you would cut.
How do you wire a series of recessed lights to a single switch when the power goes to the lights first?
If you already know how to put one fixture on a 3-way, just connect white-to-white and black-to-black from one light to the next. If you're changing from a single switch to the 3-way, the exact wiring will depend on whether the power comes from the breaker box to the switch or the existing fixture. I'll assume you're starting from scratch or have the power going to the fixture. You need #15 two-wire with ground and #15 three-wire with ground romex. Run two-wire from the breaker box to the first light fixture. Pull a another two-wire from this box to switch A and a three-wire between the switches. String two-wire from the first light to the second, second to third, etc. In the first box, connect white from source to the white fixture wire and the white going to the second box; black from source to the black to switch A; and the black fixture wire to both the white to switch A and the black to the next fixture. At each of the other 5 fixtures, connect all white to white and black to black (three pair in each box except the last one). At switch A, connect the white from the fixture to the common (center) connector and the black directly to the black going to switch B. The red and white wires going to switch B are connected to the two outside connectors of switch A. At switch B, the black goes to the common connector and the red and white to the outside connectors. At each box, connect all the bare wires (second ground) to each other and to the fixture or box. Now turn the power back on. If all the connectors are tight, power should follow the black wires from source past the fixture and switch A to switch B. From there it will go through one or the other of the travellers and, if switch A is in the same position as B, up the white switch leg to the fixtures, turn on all the lights and go back to ground.
Is the white wire in the thermotat a neutral?
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
Add new gfci from an existing switch?
Find the Hot side of the switch (Where there is voltage regardless of position of toggle on switch). Tie in new Black wire to GFCI. On wire nut with white wire tie in new white wire to GFCI. Do the same for the bare ground wire, if there is one.
How do you connect multiple lights to one switch starting at the light?
You put switch in series with the black supply wire and the black wire to the first light. Then connect black wire of first light to black wire of second light, black wire of second light to third light and so forth. Do the same with the white wires and ground wires.
Can you wire a light switch with only one 14-2 wire?
If the power feed goes directly to a fixture, or if you are wishing to switch a receptacle that is not now switched, you can us a 14-2 NM cable to install a "switch loop", provided the circuit is no larger than 15 amps. To do this, after running the 14-2 NM cable, connect the WHITE conductor of the 14-2 to the hot wire. At the switch, connect the black and white conductors to the switch terminals. At the fixture or receptacle, the black wire of the 14-2 NM cable now becomes your switch leg and is connected to the black conductor of the fixture or brass terminal of the receptacle. The NEC (for the United States) requires that the switch be fed with the white wire and the black wire be used as your switch leg.
