Why is the white wire hot?
Why is the white wire hot? Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source.

Can a smart switch burn out?

Does smart switch use much electricity?
However, it is crucial to recognize that smart switches will use more energy than a standard switch. In general, smart switches with Wi-Fi controls will use two watts of power while idling, while a ZigBee or Z-Wave switch will use about 0.5 watts at idle. Energy savings does tie directly into user behavior.
