A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
Electrical Wire Red Black White Ground. When measured with respect to the white neutral wire the red wire carries the same 120 volt current that the black one carries making the voltage across these two hot wires 240 volts. White wires augmented with red or black tape or markings are used as hot. Attach the black wire to the outlet you want to always be on usually the top one and the red wire to the switched outlet.

Remember black and red wires are always hot meaning they are source wires that carry power from the electric service panel to a destination such as an outlet or a light. When a white wire is augmented with a red or black color marking this often indicates that it is being used as a hot wire rather than a neutral wire. The colors regulated by the national electrical code in the united states are standardized for safety. Active red neutral black earth green.
The metal conduit is allowed to serve as the ground conductor so bare or green wires are not used.
The list below also outlines the different colour. When measured with respect to the white neutral wire the red wire carries the same 120 volt current that the black one carries making the voltage across these two hot wires 240 volts. The different colors of electrical wires indicate the function of the wire with black and red indicating the wires carry electric current white usually indicating neutral charge and green indicating the wire is grounded. However a black wire can never be used as a neutral or ground wire or for any purpose other than to carry a live electrical load. When a white wire is augmented with a red or black color marking this often indicates that it is being used as a hot wire rather than a neutral wire.
Electrical Wire Red Black White Ground. Attach the black wire to the outlet you want to always be on usually the top one and the red wire to the switched outlet. Electricians often use black red or.
