People Shocked in U.S. Swimming Pool.

Alasdair Anderson:

The fatal current doesn't circulate in the middle of the swimming pool. You need to be at the edge, preferably grabbing on to a metal hand rail or similar.

Interestingly the Americans have also managed to kill people swimming in rivers/marinas/lakes due to connecting their boats to a shore supply and getting circulating currents (https://www.boatus.com/seaworthy/magazine/2013/july/electric-shock-drowning-explained.asp), mainly children, and even avoiding the need to grab an earthed rail if the voltage gradient in the water is sufficient. It may also be enough in a swimming pool. Note that the lack of RCDs in the supply systems (a requirement in the UK for supplies to small vessels as far as I am aware) is a major reason for such faults being undetected until it is too late.
