Field hub — common codes, ownership boundaries, and links into the fault database.
Eaton switchgear / PQ field hub
Eaton gear on charging sites creates tickets that look like "all chargers failed." Start at the one-line and breaker, not the first EVSE HMI.
Ownership
- Electrician / PQ: breakers, GF, arc-flash, transformers, CTs, UPS controls.
- EVSE tech: timestamp correlation, LMS/session coincidence, scrubbed evidence pack.
- Engineer: settings changes, upsizing, filter banks.
Ranked patterns
- Feeder trip at peak — coincident ramp / lug heat / curve. SWG-TRIP.
- GF / arc-flash — life safety; qualified only. SWG-GF, SWG-ARC.
- Transformer overtemp / harmonics — cooling + engineering. SWG-XFMR, SWG-PF.
- Door interlock / UPS dead / CT reversed after service — restore controls and sensing before EVSE blame. SWG-DOOR, SWG-UPS, SWG-CT.

SWG-TRIPEaton · SwitchgearFree sampleFeeder breaker trip charging peak
The Eaton feeder breaker serving the depot trips right at a charging peak, taking multiple EVSE units Faulted or fully dark at once — the breaker handle sits mid-trip when you find it, and idle voltage checks looked completely normal before the peak, which is exactly the pattern that sends techs chasing individual charger faults instead of the shared feeder that actually failed.
