Possible Causes

Generator undersized for motor starting current, Weak engine output due to fuel issues, Loose electrical connections causing voltage sag, Faulty load management modules

How to Fix / Troubleshooting

Safety First: Large motor loads can cause sudden current surges. Coordinate with an electrician or HVAC contractor when adjusting loads.

  • 1. Stagger large loads: Avoid starting multiple large loads at the same time. Use load management modules if provided with the GE system.
  • 2. Inspect fuel system: Ensure fuel pressure and flow are adequate so the engine can respond to load changes.
  • 3. Tighten electrical connections: Check main lugs in the generator, ATS, and panel for tightness to minimize voltage drop.
  • 4. Consider soft-start devices: For large air conditioners or pumps, install soft-start kits or dedicated load management per GE recommendations.
