Which color code represents hot wires in residential electrical installations?

In residential electrical installations, the color black is used to represent hot wires. This standard is part of the National Electrical Code (NEC) and is important for safety and consistency in wiring practices. Hot wires are those that carry current and can present a shock hazard if not handled properly.

Using black for hot wires helps electricians and anyone working with electrical systems to quickly identify the function of each wire in a circuit. This color coding plays a vital role in preventing accidents and ensuring proper connections are made.

Other colors have specific meanings as well. For instance, white typically signifies neutral wires, green is reserved for ground wires, and blue can be used for different applications, but is often found in multi-wire systems. Understanding these color codes is crucial for anyone involved in electrical work, as it aids in both safe installation and troubleshooting of electrical systems.
