Wiring a Switch Box and Flush Lights
An electrician wired a single pole switch box to two ceiling flush mount fixture boxes. I can't figure out what they did to hook it all up now that I finished the room.
All wires are Romex 12/2.
Fixture 1 seems to have the source power, with one spliced Romex end with electric tape wrapped around the Black and White.
There is a second Romex cable here, presumably to head down to the switch.
Fixture 2 has a single Romex end, presumably leading to the switch box. In the switch box there are 3 romex cables. One was marked \ feed\ , which I think would lead to the fixture box at Fixture 1.
So I can't figure out why there are 3 cables in the switch box and how to wire this.
After you have verified the power is off proceed. Ohm Meter Setting: Set your Ohm Meter to measure a low resistance setting such as Rx1K or 1000 Ohms. Touch the test leads together to test your meter, you should get a 0 reading which means there is zero resistance between the two test leads. Identifying a set or pair of wires: Select the pair of wires you need to identify at one location. Remove the insulation back about one half inch. Twist a wire connector on these two wires creating a temporary splice. Next: Select one of the pairs of wires you are working with. Remove the insulation back about one half inch. Testing with the Ohm Meter: Now using the ohm meter place the one test lead to one wire, and the other test lead to the other. If you get a 0 resistance reading go to the pair of wires where the wire connector creates the temporary splice and remove the wire connector. Re test the ohm meter on the other pair of wires and see if you still get the 0 reading. If there is no 0 reading then you have identified this pair of wires. Label this pair of wires and proceeded with the test to identify any other pairs of wires.
