I have a Sub-Zero 361RFD and need the Wattage for a generator power formula as a result of April 27 tornado outbreak in Alabama.

This may help:

Look on the info plate on the door frame or behind the coil access vent. It will give you the amperage. Multiply that times 120Volts for the wattage. E.G. 4.5 Amps X 120V=540 watts. Since you will possibly be using more power for other purposes and have starting loads and defrost heaters, I'd get at least a 1.5KW generator.
