Cummins Onan P9500df delivers 9,500W surge, sufficient for a 3.5-Ton central A/C with soft-starter. Inverters under 7,500W surge will trip breaker overcurrent protection on direct compressor starts.
72-Hour Fuel Logistics
At 50% load over 72 hours, continuous gasoline generators consume ~56 gallons (11x 5-gallon cans). Direct utility Natural Gas hookup eliminates fuel storage degradation, winter freezing, and gas station queues.
NEC 250.20 Neutral Bonding
Champion has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.
The Champion 201067 delivers 9000W peak surge compared to 9500W on the Cummins Onan P9500df. Starting a 3.5-ton central air conditioner requires an electronic soft-starter to reduce compressor inrush below breaker trip thresholds.
72-Hour Outage Fuel Logistics
At 50% electrical load over a 72-hour power outage, 201067 consumes about 59 gallons while Onan P9500df burns 48 gallons. Homeowners need 12 sealed 5-gallon gasoline cans or utility natural gas.
