How can Stray Current cause problems in water?
As an example, if a wooden pier has power and lighting, and if the Stray Voltage on the Electrical System Ground is sufficient, a person in the water near the ground-to-water contact point will be exposed to voltages that diminish as he / she gets further away from the contact point. If the difference in voltage from one side of the body is substantially different from that on the other side of the body, the person will feel a shock, and / or be electrocuted.
