Whats the big plug now found on some appliances like hair dryers?
The large box found on some appliances can be either an appliance leakage circuit interrupter (ALCI), an immersion detection circuit interrupter (IDCI), or a ground fault circuit-interrupter (GFCI). They work in different ways, but they’re all intended to shut off the power to an appliance under abnormal conditions, such as immersion of an appliance in liquid. Just because you have an appliance with one of these devices, it doesn’t mean that it’s okay to drop the appliance in water. The rule “electricity and water don’t mix” still applies.
