GFCI breaker tripping after a heavy rain
Why it happens here
West Plant City gets afternoon thunderstorms through the summer, and moisture can get into an exterior charger or a conduit body. Once water reaches the terminals, the GFCI senses a ground fault and trips. It's a safety feature doing its job, but it's annoying.
Our approach
We inspect the conduit fittings, the charger gasket, and the connector for water intrusion. If the charger is mounted in a spot that takes direct rain, we recommend a different location or a weatherproof enclosure. Then we retest the GFCI under load.
