I have a small snow machine that I purchased. It comes in a wooden box with metal, I assume aluminum or maybe stainless steel, trim around it. It connects directly to a standard 110vac power. Obviously there is liquid involved as well.
The strangest thing is happening. I have one worker who, whenever he touches the metal trim, gets shocked. It is continuous and happens regardless of how many times he touches it, so it isn't static. Everyone else can touch it without getting shocked. But if he touches someone while they are touching it, they both get shocked. He has tried different clothing, shoes, etc to figure out why he is the only one, but no matter what, he is the only one who gets shocked.
It makes no difference if the machine is turned off or on.
Anyone have any ideas? It's got me stumped.

The shoes and socks can be leather and with sweat and conduct many uA of current.
The machine has leakage current and 0.5mA (500 uA) can be felt but is generally considered safe and is the IEC/UL/CSA limit. It may be more and you ought to try measure it and fix it.
