Rain alone should not stop a correctly installed, outdoor-rated charger — charging in rain is normal, as our guide to charging an electric car in the rain sets out. So when a charger turns off in wet weather, something switched it off: a ground-fault device, a breaker, the charger’s own fault stop, or nothing electrical at all. Each author leaves different evidence, and a different person to fix it.
Key Takeaways
- “Off in the rain” has four authors — ground-fault device, breaker, the charger itself, or the car ending the session. Each leaves evidence.
- Record before resetting: board state, charger state, the car’s account, and whether dry evenings at the same hour do it too.
- Rain explains leakage reactions; it does not explain charger faults or dry-weather trips noticed on wet days.
- A repeating wet-weather fault is electrician work. Never bypass the protection that reported it.
The Four Ways “Off” Happens
| What you find | What switched it off | Where the fix lives |
|---|---|---|
| A ground-fault device at the outlet or board has tripped | Leakage protection reacting to moisture reaching a live part in the path | An electrician finds the entry point — the protection is reporting, not malfunctioning |
| The breaker has tripped, and no ground-fault device has | Too much current — wet, cold evenings are when heating and charging stack hardest | The installation’s load design; our guide to a charger tripping the breaker separates the causes |
| Board devices are all fine, but the charger is dark or showing a fault | The charger stopped itself | Record the indication exactly; the manufacturer route, not the weather |
| Everything is live and normal, and the session is simply over | The car ended it — a limit reached, a schedule, a finished charge | Nobody. Rain was standing next to a coincidence |
The One Dry-Day Look That Separates Them
The common mistake is resetting everything at once, which destroys the evidence all four authors leave differently. On the next dry day, in this order:
- Board first. Note which device, if any, is tripped — before touching it. That fact eliminates half the table.
- The charger as found. Photograph its display or indicator state exactly as the rain left it.
- The car’s account. Its charge level against its set limit, and whether it recorded a completed or an interrupted session.
- The coincidence test. Does it also stop on dry evenings at the same hour? If yes, rain was never the variable — time of day was.
Only after that record does a single reset become a test rather than an evidence bonfire. If the stop returns, the return is the result.
What Rain Genuinely Explains — and What It Does Not
Rain explains exactly one row well: moisture reaching a connection that should stay dry gives ground-fault protection something real to react to. Our explainer on GFCI protection for EV chargers covers why it is there. Rain does not explain a charger-side electronic fault, or a breaker that also trips in dry weather — those were simply noticed on wet days first.
Two rules hold for every row. A wet-weather-only fault is still professional work: “dry it out and retry” is not a plan for a repeating fault, because drying hides the pattern the electrician needs. And a protection device is never bypassed, swapped for a plain one, or held in to test a theory — the device that trips in the rain is the witness, not the suspect.
Why the Rating Points Away From the Unit’s Surface
Sealing ratings are stated facts, and they matter here as evidence. The EVDANCE EV-ACS3210E 32A Type 2 portable charger is rated IP66, and the EV-ACT5006T 48A Level 2 wall charger (up to 48 A, hard-wired or NEMA 14-50P, NACS, 25 ft, ETL/FCC/CE) is rated IP65/IP66 — rain on either unit is inside what its listing states. So a rain-correlated stop points away from the charger’s surface, toward the board devices, the path water can reach, or the car’s own record.
Frequently Asked Questions
It only stops in heavy rain. Light rain is fine. Does that change the answer?
It strengthens it. A stop that tracks rain severity fits moisture reaching something it should not — the leakage row. Record the pattern for an electrician; severity-tracking faults are still faults.
Can I reset it and keep charging tonight?
One reset, after recording what you found, is a reasonable test. If it stops again, that is the answer — leave it off and make the call. Charging through a repeating trip is never an option.
My neighbour has the same charger and it never stops in rain. So mine is faulty?
Not necessarily. The charger is the one part the two setups share; the outlet, its cover, the circuit and the car’s settings all differ. Different behaviour from the same model points at the installation first.
