What is the standard color for a hot wire in electrical coding?

The standard color for a hot wire in electrical coding is typically black or red. In most electrical systems, hot wires are used to carry current from the power source to the load. Black is commonly utilized for the primary hot wire, while red is often used for a secondary hot wire in systems that require multiple phases or circuits.

This coding is crucial for safety and identification, allowing electricians and technicians to easily recognize which wires are live and potentially hazardous. The use of clearly defined colors helps prevent mistakes during installation and maintenance, ensuring that power is properly managed within wiring systems.

The other options represent different functions in electrical wiring: green is reserved for ground wires, white is used for neutral wires, and yellow may be used for switch legs or other specific applications that are not primary sources of power.
