I have had both 110 aerators and 220 aerators short out in ponds. Each time when I went out to check to see why they were not running the water close to the aerators had an electrical charge present about 3 feet out from the aerator. There was more of a sharp tingle than a shock to it. Each aerator was about 10 feet from the bank. My point is when I stepped in the water it did not electricute me. Obviously, I did not touch any wires or the aerator after feeling the electricity in the water as I approached. I know our aerators which are 220 use less eletricity and the motors last longer.
Whenever people ask me an electrical question I tell them "I am an expert on electricity". I know that it will kill the hell out of you".
