Troubleshooting · Breakers · GFCI
A breaker or ground-fault device that trips during charging is a warning, not an annoyance. In apartments and condos the cause is often a shared circuit, an amp setting that is too high, or moisture at an outdoor outlet. Here is what a driver can safely check, and when to stop and get a licensed electrician. Not legal or electrical advice.
Breakers trip to protect wiring from overheating, and ground-fault devices (GFCI) trip when current is leaking somewhere it should not. Resetting over and over without finding the cause risks damage or fire. Only reset once; if it trips again, stop charging and follow the steps below.
| What you see | Likely cause | What to do |
|---|---|---|
| Breaker trips after 30–90 minutes of charging | Charger amp setting too high for the circuit, or other loads on the same circuit | Lower the charger setting to match the breaker (80% rule); ask whether the circuit is shared |
| Breaker trips the moment you plug in | Fault in the cord, plug, outlet or wiring | Stop. Do not reset again. Get a licensed electrician to inspect |
| GFCI trips at an outdoor stall, often in rain or snowmelt | Moisture in the outlet, plug or cover | Stop. Ask for a weatherproof in-use cover and an inspection; never dry and retry repeatedly |
| Trips only when a neighbour charges or a heater runs | Shared circuit or building capacity limit | Ask the building about a dedicated circuit or load management |
| Plug or outlet feels hot, looks discoloured, or smells | Loose or worn contacts overheating | Stop immediately. Do not use the outlet until an electrician repairs it |
EV charging is a continuous load, so Canadian rules size it at about 80% of the breaker (Canadian Electrical Code Rule 86-302). A setting above that is the most common cause of a slow trip.
| Breaker | Max continuous charging current | Typical use |
|---|---|---|
| 15 A, 120 V | 12 A | Level 1 on a household outlet |
| 20 A, 120 V (dedicated) | 16 A | Level 1 on a dedicated circuit |
| 30 A, 240 V | 24 A | Small Level 2 |
| 40 A, 240 V | 32 A | Mid Level 2 |
| 50 A, 240 V (NEMA 14-50) | 40 A | Full plug-in Level 2 |
If you do not know the breaker size, ask your landlord, property manager or an electrician before changing settings.
A slow trip usually means the charger is drawing more than about 80% of the breaker for a long time, or something else shares the circuit. Lower the charger setting to match the breaker and ask whether the circuit is dedicated.
Moisture in an outdoor outlet, plug or cover is a common cause, but so is a fault in the cord or charger. Stop charging and have a licensed electrician inspect; do not bypass the GFCI.
No. The breaker protects the wire. A bigger breaker on the same wire can overheat it. Only a licensed electrician should change circuits, with the permit your province requires (in Ontario, an ESA permit).
No. Reset once at most. If it trips again, stop charging and get the cause found.
Report it to your landlord or property manager in writing. The building arranges a licensed electrician for its own wiring.
It charges more slowly but safely. Use the hour math on our Level 1 vs Level 2 guide to see whether the lower setting still fits your overnight window.
