ReaLoad Technical Verdict & Engineering Dossier

Motor Surge & HVAC Starting

Predator 13000 Tri-Fuel (71386) delivers 13,000W 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

Bonded neutral generators require terminal bridge disconnection before connecting to home service panels to prevent double-ground GFCI trips.
