The Thermostat Wire Color Code You Need To Know
I have 2 black wires and 1 white wire. All home electrical wires made in the us. They should both be of the same wire gauge. I tried to figure out the path of power but i wasnt getting the readings i was expecting. In the outlet box you will have a black white and bare ground wire. The old switch had 3 screws on it. The ground is screwed into the box so i understand that.
However if you need to rewire a light switch or a plug socket you may occasionally come across two black wires. The easiest and safest way is to use a multimeter to test for current. Youll have two cables in the switch box a live one with a black and white wire and the one going to the outlet which has a red black and white wire. Black means hot white signifies neutral and green indicates ground. Essentially you connect the white and bare wires directly to the light and switch the black wire hot through a switch. When i pulled out the existing switch i noticed i have 2 black wires and a white wire connected to the old switch.
2 light brass and 1 dark brass named common. Its essential that you determine which black wire is hot before proceeding. Knowing which wire does what and goes where is imperative not only in the correct configuration of an electrical system but also for your familys safety.
