What color signifies Class B wiring?

Class B wiring is indicated by the color red. This color coding is part of a standardized system used to easily differentiate between various types of wiring, as each classification serves a different function in electrical systems. Class B typically refers to wiring that carries lower voltage and is often used for control circuits. The red color is a clear signal to electricians and technicians about the specific wiring type, helping to maintain safety and organization during installation and maintenance. This standardized color coding plays a critical role in ensuring that wiring is handled correctly according to electrical codes and safety regulations.
