| How
to identify Black hot wire inside box: Requires ordinary tester. With residential 120 Volt wiring, each box has only 1 hot wire. By code the hot wire is black. This test assumes you are testing ceiling box, wall box with plug, wall box with multiple plugs, outdoor box, wall box with several switches, wall box with one switch. Test does not necessarily work with 3-way switch, since switch on other end can affect outcome. Test does not work with 240V circuits. Turn off power. Mark wires with tape and numbers. Take photo of wires. Disconnect all wires from each other and separate. Turn power back on. Using ordiinary tester, test each wire to bare ground. Only one wire will show power when tested to ground. That is the Black hot wire. Mark it. Turn off power. Reconnect wires. |
