We have discussed this safety issue on other treads already.

> Simple calculations :  
> 30mA gives the human body respiratory paralysis (you already feel pain under 10mA)  
> Human body resistance is roughly something around 2000 Ohm (wet body, considering electricity breaks down human skin and therefore lowering the resistance)  
> Max voltage would be = 2000\*0.03=60V

If you can waterproof them just do it. For your own safety. Current won’t forgive you that easily
