I cannot think of any installation dead tests that cross wired installation would not pass.
Andy BSo a Ze or ZDB test could check for a supply wiring error? I think that's back to where we were - discussing live Zs tests on ALL final circuits.
You have to do a live test somewhere along the line.
Three phase you will be checking the phase sequence as well as polarity, I had an interesting discussion with two electricians in a pub one night, one of them works for a generator hire company and makes great use of a long wander lead to ensure he is hooking up temporary supplies correctly.
