What are the electrical requirements for the Whirlpool Thin Twin?

The Thin Twin requires a three-wire, single-phase, 120-volt, 60-Hz, AC-only, 15- or 20-ampere, fused electrical supply. A time-delay fuse or circuit breaker is recommended, and a separate circuit serving only this appliance is preferred. The appliance must be plugged into a grounded 3-prong outlet — do not use an adapter or extension cord. (Page 3)
