Hi Nick

You are a thinking kind of guy. What is your thought about what would
happen if the cord *was* plugged in to a generator? (A generator with no
connection to ground.)
I thought that socket was for 200 volt cirtuits. If the socket did have
~200 volts between terminals, and they both contacted the water, is it
likely that the people would be in a high potetial area?
Does anyone know what happens if 220 VAC across terminals spaced 1 inch
apart is imersed in swimming pool water?

Jerry

On straight line connecting the terminals the gradient is 220V/inc therefore
an ant 1/2" long midway between the terminals would feel like touching a110V
outlet with the hand while standing on the neutral wire.

To visualize the electrical field emanating from the socket, allow some
simplification and inaccuracies, still leaving the concept intact.
If you draw a circle 10 feet in diameter centered 5 feet from the outlet on
a line perpendicular to the 1" spacing, you can think as the 220V are evenly
spaced across the 31.4 feet of the circumference.
A man 6 feet tall floating tangent to such circle will be exposed to
6x220/31.4 or nearly 40V.
If the man was standing in the water on the same circle, at breast level,
arms down, looking toward the outlet,
the 2 feet or so across its thorax would feel about 13V.

For every roughly circular path you can draw around the outlet you can apply
the same concept, the voltage gradient will be 220/path-lenght.

In reality the lines of constant gradient are not circles even under ideal
conditions. I a real pool depend from the water composition and
distribution, the location and conductivity of the wall and the structures
immersed, swimmers included and their geometry.

For example if the wall were made of copper, then the voltage between any
two points would be minuscule.
