What is the safety benefit of using a polarized plug?

Explanation:
Polarization helps keep hot and neutral wires connected in the correct places. The wider blade is neutral and the narrow blade is hot, and outlets are built to match that. When a device’s switch interrupts the hot conductor, any exposed metal parts are less likely to carry live voltage, which reduces the chance of an electric shock if you touch them. It doesn’t provide grounding, it doesn’t increase efficiency, and it doesn’t guarantee a universal fit in every outlet.
