Genmax GM12000iET delivers 12,000W 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
Genmax has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.
The DuroMax XP15000EH delivers 15000W peak surge compared to 12000W on the Genmax GM12000iET. 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, XP15000EH consumes about 104 gallons while GM12000iET burns 76 gallons. Homeowners need 21 sealed 5-gallon gasoline cans or utility natural gas.
Home Panel Interlock Safety
DuroMax XP15000EH features a bonded neutral, requiring ground jumper removal before connecting to home breaker panels.
