What are the color codes for electrical wires?
U.S. Electrical Wiring Color CodesPhase 1 – Black.Phase 2 – Red.Phase 3 – Blue.Neutral – White.Ground – Green, Green with Yellow Stripe, or Bare Wire.
Is the yellow wire positive or negative?
In DC circuits, the Positive is any color(generally red) and negative is black. Hence a yellow wire may be Positive if the other wire is black(negative).
Why do wires have 4 wires?
Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.

Car batteries, like regular AA batteries, have positive and negative ends. The positive (+) end is identified with a red plastic cover or connected to red wires, while the negative (-) end will have black markings.
Is yellow wire hot or neutral?
Yellow wires are almost always used as switch legs for outlets, fans, or lights. White or gray indicates a neutral wire, which provides the return path for the current carried by the hot wires and is grounded within the electrical panel.
Is blue wire live or neutral?
Blue = Neutral The neutral wire transfers electricity away from the appliance to avoid overloading. It is located at the end of the circuit for connection after the electricity has flowed around the live and earth wires.
What does a yellow wire mean?
Yellow and blue electrical wires are also used to carry power but are not for wiring the outlets for common plug-in electrical devices. These colors are used for the live wire pulled through conduit. You’ll use yellow mainly as switch legs to fans, structural lights and switched outlets.
