A fault or inductive build up is one thing, the gen has plenty of safeties to deal with that, but if someone is touching it during that period, we want to make certain they don't get hurt.


George that can not be prevented no mate how low the resistance to ground is.

It will be imposable to 'connect' the generator frame to earth in a way that would eliminate the danger during a fault.

This is exactly why I posted this thread, there are no real answers.

In some ways ways it would be better if the generator and the building it was suppling where isolated from the earth but that is not possible either.
