Control wiring and power wiring difference

Question

Accepted Answer

Control wiring and power wiring are different in terms of their purpose and the type of electrical components they connect.

Control wiring is used to connect control devices such as switches, relays, and sensors to control panels or systems.
Power wiring is used to connect power sources, such as electrical panels or generators, to electrical loads.
Control wiring carries low voltage signals, typically in the range of 24V or lower, while power wiring carries high voltage electrical power, typically 120V or higher.
Control wiring is often smaller in gauge compared to power wiring, as it carries less current.
Control wiring is usually routed separately from power wiring to minimize interference and ensure proper functioning of control systems.
Examples of control wiring include wiring for lighting control systems, HVAC control systems, or industrial automation systems.
Examples of power wiring include wiring for electrical outlets, lighting fixtures, or motors.
Control wiring is typically color-coded to distinguish between different control signals, while power wiring may follow standard color codes for safety and identification purposes.
