Although a white wire should only ever be connected to another white or grey wire. When wiring for dc power there are typically going to be either two or three wires.
Electrical Wire Colors And What They All Mean Solved Bob Vila
Red and black wire means. The coloring is as follows. Always assume black wires are live. White and grey wires are your neutral wires and those should never be connected to brown which is a hot wire. This color of wire is used to transfer power to switches and outlets in all types of circuits. 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. Electricians often use black red or blue wires to deliver electricity to a circuit from the main panel.
In standard 120 volt wiring the hot wire is black but it can also be red. 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. They may use other colors for. White wires augmented with red or black tape or markings are used as hot. Red or orange wires are often used to provide the secondary phase voltage in a 220 volt application. Negative the wire for the negative current is black.
Black wires are always hot wires meaning that they carry electricity. One is that the outlet is a 240 volt one which requires an extra hot wire. Consider all black wires to be live at all times. The red or striped wire is the hot wire for the lighting fixture of the ceiling fan so if your ceiling fan does not have a lighting fixture it will only have the three other wires mentioned in the following sections. Black wires are never used as ground or neutral wires and must always be treated with caution. In most cases you see a red wire in an outlet box only in special circumstances.
Also black wires are often used as switch legs in circuits which is the connection linking a switch to the electrical load. Red wires are also hot wires. In 220 volt circuits red wires are the secondary live wires. Red goes to black or black to red because those are your hot wires. Moreover sometimes this wire can come directly from the main circuit breaker in order to always be on. Positive the wire for the positive current is red.
The white wire is the neutral and all other colors are hot. Another is that the box is on a circuit three way switch loop. The colors regulated by the national electrical code in the united states are standardized for safety. Black wires are used to provide power in the circuit.
