What are the electrical requirements for installing the WFW9400SW00?

The washer requires a 120 volt, 60 Hz, AC only, 15- or 20-amp fused electrical supply, and a time-delay fuse or circuit breaker is recommended. It must be plugged into a grounded 3-prong outlet — do not use an adapter or extension cord. A separate circuit serving only this appliance is recommended, and the washer must not be connected to a gas pipe for grounding.
