Possible Causes
Incorrect bonding between neutral and earth at subpanel, Reversed neutral and earth conductors, Faulty neutral sensing circuit, Shared neutral issues with other loads
How to Fix / Troubleshooting
Safety: Neutral‑earth faults can be hazardous and must be corrected by a qualified electrician.
- Step 1 – Verify panel bonding: Ensure that neutral and earth are bonded only at the main service panel, not in subpanels feeding the charger.
- Step 2 – Inspect wiring: With power OFF, confirm that neutral and earth conductors are correctly landed on their respective terminals in the charger and panel.
- Step 3 – Measure N‑PE voltage (electrician): With power ON, measure voltage between neutral and earth at the charger. Significant voltage indicates a wiring or load issue.
- Step 4 – Isolate shared circuits: Avoid sharing neutrals with other high‑load circuits that can create N‑PE imbalances.
- Resolution: Correct any wiring/bonding issues. If N‑PE conditions are normal but E19 persists, the neutral‑earth sensing circuit on the main control board may be faulty.
