O.K., thanks for your reply.
All I will add is that for ages I have arranged my test / repair bench to be fed via an isolation transformer unit which feeds multiple 3-pin sockets. That transformer is internally configured for 120v. - 0v. - 120v. bi-phase output with the 'E' / 0v. centre point connected to supply earth inside the commercially-built isolation transformer unit which has full Government safety approval - plus full ELCB protection and fuses fitted. The idea of the bi-phase arrangement is simply to reduce the magnitude of any 'L' - 'N' electrical shock that I might receive.
I haven't had any mishap yet.
