also as long the device is not sealed it can relase the vapor from the source.

if it was in sealed box or device it will blow the gasket out or go thru back to the power source where the breaker or fuse box is located.

myself i did see one of the device did boil the water pretty good later i learn that the ground wire and neutral wire was pretty corroded and cause all the water in the box vaperized and see the box inside all green

oh yeah one more thing that the boiling water can burn your hand if you dont look out !!!! [Linked Image]
