Kohler PRO7.5 delivers 7,500W 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
Bonded neutral generators require terminal bridge disconnection before connecting to home service panels to prevent double-ground GFCI trips.
The Kohler PRO7.5 delivers 7500W peak surge compared to 28000W on the Westinghouse WGen20000c. 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, PRO7.5 consumes about 59 gallons while WGen20000c burns 140 gallons. Homeowners need 12 sealed 5-gallon gasoline cans or utility natural gas.
Home Panel Interlock Safety
Kohler PRO7.5 features a bonded neutral, requiring ground jumper removal before connecting to home breaker panels.
