GFCI faults after heavy rain
Why it happens here
Exterior junction boxes and conduit bodies take on water during Florida storm season, especially when the fittings are not raintight. Once moisture reaches the terminals, the GFCI senses a ground fault and shuts the charger down.
Our approach
We use raintight fittings, seal every exterior penetration, and mount boxes where water drains away. After a storm, we offer a quick inspection that checks the GFCI, the terminations, and the cable jacket. It is a short visit that prevents a much bigger repair.
