Most people think water automatically trips a GFCI.
Not quite.
In this experiment, I connected a cucumber to hot and neutral while it was sitting in water and plugged into a GFCI-protected outlet.
Current was flowing, but the GFCI didn’t trip.
Why?
Because the electricity leaving on the hot wire was returning on the neutral wire.
The GFCI only trips when it detects an imbalance between the current leaving and returning. Once a ground fault is introduced, the GFCI reacts and trips.
This is exactly why GFCI protection is required in bathrooms, kitchens, garages, outdoors, and other wet locations.
Electricity and water can be a dangerous combination. Always use proper GFCI protection where required by code.
