From an earlier post of mine:
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 electrical safety approval.
Note: That 'earth through' arrangement has now been disconnected my me.
