Electric current requires a circuit of conductors, including a wire, to make its way through an appliance or device. One of the most important factors in successfully setting up a conductor is to correctly identify the correct wire's color. The different colors of wiring represent the various types of current and voltages that can be powered through the wires. One of the most common types of current is Alternating Current (AC).
Knowing what color wire is used for AC is essential information for any homeowner, electrician, or technician that needs to install and work with electrical wiring. When dealing with AC current, it is very important to always use the right colored wire. Different colored wires provide different functions and safety measures, and using the correct one is necessary for proper installation and electrical safety.
For AC current, the common wire color is black. The black wire is usually connected to a live terminal as well as to the conduit box. This is the hot wire in a standard electrical setup, and carries electricity to the appliance or device that it is connected to. Neutral (white) and ground (green) wires are also commonly used. The white wire should be connected to the neutral terminal of the power supply. The green wire should be connected to the ground terminal, which will be connected to the body of the device or appliance.
These are the general rule of thumb for identifying the color of wire for AC current, but in some cases other colors may be used. It is important to always read and follow all instructions and diagrams that come with the device when attempting to install wiring. This will help ensure that everything is wired correctly and safely. Make sure to always double check all connections before powering up the device.
