Subject: Re: VDG trips breaker



This has not happened to us.
You may want to check the wiring of the outlet, to make sure it has a
proper ground, and to see if the "hot" and "cold" sides are wired
up correctly. Not sure if these would cause it, but a place to start

THe VDG do not always have a separate ground wire so we added one
(to the case) and connect the wire to the ground of the building.
Will still shock you if you are not careful.
