What are the electrical requirements for the portable dishwasher model?

The portable dishwasher requires a power supply of 120 volts, 60 Hz AC, 15 or 20 amps. It must be plugged into a grounded 3-prong outlet. Do not remove the ground prong, use an adapter, or use an extension cord, as doing so can result in death, fire, or electrical shock. (Page 7)
