Phil,

You're right about people not testing GFI receptacles. One survey showed that about 18 or 19% of GFI's no longer provide GFI protection.

The water would not be a good enough conductor to cause a breaker to trip or a fuse to blow, but it would probably allow enough current flow to get someone killed if the GFI doesn't function.

Few things are harder to put up with than the annoyance of a good example.
