Possible Causes

Open breaker in generator subpanel, Loose neutral connection, Miswired ATS load conductors, Overloaded branch circuit tripping

How to Fix / Troubleshooting

Safety first: During an outage, ensure the generator is supplying power and the ATS is in generator position. Use caution when working in live panels; consider hiring an electrician.

  • Check breakers: Inspect all breakers in the generator subpanel or ATS load center. Reset any tripped breakers.
  • Neutral connections: Verify that the neutral bar connections are tight and that the neutral from the generator is properly landed.
  • Identify affected circuits: Map which circuits are dead and confirm they are actually fed by the generator system.
  • Correct wiring: If circuits intended to be on generator are not connected in the ATS or subpanel, an electrician must rewire according to the DuroMax installation guide.
