ReaLoad Technical Verdict & Engineering Dossier

Motor Surge & HVAC Starting

Predator 4375 delivers 4,375W 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

WEN has factory floating neutral, safely compliant with 3-pole transfer switches and manual panel interlocks without ground loop faults.

ReaLoad Technical Verdict Dossier

Motor Inrush Starting Surge

The Predator 4375 delivers 4375W peak surge compared to 4750W on the WEN DF475iX. 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, 4375 consumes about 36 gallons while DF475iX burns 30 gallons. Homeowners need 8 sealed 5-gallon gasoline cans or utility natural gas.

Home Panel Interlock Safety

Predator 4375 features a bonded neutral, requiring ground jumper removal before connecting to home breaker panels. Follow NEC 250.20 safety grounding rules.
