Question

Quizplus · Accepted Answer

Snap switches, including dimmer switches, must be connected to an equipment grounding conductor to ensure that any electrical faults are carried safely to ground. Additionally, even if a metal faceplate is not installed, the switch must be able to connect to the equipment grounding conductor to prevent any potential electrical hazards. A bonding jumper or a switch mounting strap may provide this connection, but the equipment grounding conductor is the most important and necessary connection. Non-metallic yokes are used in switches to insulate them from the electrical circuit and do not provide a means of grounding.
