I have always been confused on when to worry about the scope ground, so when using a PC scope I have run on battery power.

With a plain transformer-powered layout, would I be correct that the secondary of the layout transformer provides the necessary isolation, and that a grounded scope is ok?

If so, where does the isolation break down? The connection in a TMCC or Legacy base?
