ReaLoad Technical Verdict & Engineering Dossier

Motor Surge & HVAC Starting

Champion 100692 (14kW) delivers 6,250W 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.
