Possible Causes

Breaker undersized for EVgo charger rating, Loose connections causing inrush spikes, Shared circuit with other loads, Internal short or overcurrent in charger

How to Fix / Troubleshooting

Safety first: Repeated breaker trips indicate a problem. Do not keep resetting without investigation.

  • Verify breaker size: Compare the EVgo charger’s nameplate current to the breaker rating. The breaker should be sized per code (typically 125% of continuous load).
  • Dedicated circuit: Ensure no other loads are connected to the EVgo circuit.
  • Check connections: With power OFF, tighten all lugs at the breaker and inside the charger.
  • Observe trip timing: If the breaker trips instantly, there may be a short; if after some time, it may be overload or thermal.

If trips continue with correct wiring and breaker size, an EVgo‑authorized technician should test the charger for internal faults.
