household outlets(You're probably already aware of the fact that clothes dryers and cooking appliances (stoves/ovens) typically plug into different types of outlets to begin with, as opposed to normal household outlets. This is because those appliances run on two-phase circuits. A normal household circuit has one 120 volt phase wire and one neutral wire, whereas a circuit for a clothes dryer or stove/oven has two 120 volt phase wires. vatnik)
