Also, from the same source :-
"it is likely that the metal conduit is being used as the earth, this is standard practice with metal conduit or trunking
Assuming you have a test meter, and assuming that one of the reds is an unsleeved neutral, then measring between both reds will show 230V, measuring between one of the reds and the conduit will show 230V, this is your phase conductor (and also proves the conduit is earth), then measure the other conductor to conduit should show 0V, this is your neutral and should be sleeved black.
Obviously working safely, etc etc
