Perhaps I'm being a bit thick here, but I don't quite understand that.
Your "CT" could mean "current transformer" or "centre tap": most likely the latter. Indeed, there is the possibility that the secondaries might just be one secondary with a centre tap - which, in turn, may be connected to the core - but I think that that is very unlikely. And that, in turn, means my drawing needs a slight modification.
