What a 14 kW generator can run (typical)

A 14 kW unit can back up most essential circuits and many comfort loads in gas-heated homes. Exact capacity depends on start surges, altitude, and temperature.

• Refrigeration & pumps

  • Refrigerator and freezer

  • One sump and/or well pump (often up to ~¾–1 HP with load management)

• Heating & cooling

  • Gas furnace or boiler (blower/circulators)

  • Central A/C ~3–4 tons with soft-start or load management (varies by LRA)

• Home essentials

  • Lighting circuits (LED), outlets, garage door opener

  • Internet/router, home office electronics, TVs, microwave, small kitchen loads

Rule of thumb: 14 kW at 240 V ≈ ~58 A available. Budget ~11–12 kW for steady loads and keep headroom for motor starts. Large electric loads (range, dryer, tankless electric water heater) usually require smart load shedding or exclusion on a 14 kW system.

Built-in protection

The generator continuously monitors itself and will safely shut down for:

1. Low oil pressure

2. High temperature

3. Over-/under-speed

4. Controller fault / over-crank

5. Wiring error

6. Over-/under-voltage
