GENMAX GM10500XiT delivers 10,500W 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
Cummins has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.
The Cummins Onan P4500i delivers 4500W peak surge compared to 10500W on the GENMAX GM10500XiT. 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, Onan P4500i consumes about 22 gallons while GM10500XiT burns 66 gallons. Homeowners need 5 sealed 5-gallon gasoline cans or utility natural gas.
Home Panel Interlock Safety
Cummins Onan P4500i provides a factory floating neutral ready for standard 3-pole manual transfer switches.
