rating of transformer at 2 volt amps

:I think also that Class II xfmrs are inherently protected against a short or overload due to the winding impedance. So, they don't have to be fused (e.g., doorbell xfmr).

Right you are, Doug.
The transformer is so puny that it cannot put out enough current to get the external wiring hot. Stereo speakers, intercooms, telephones, security systems, etc are all class II. Your 120/240 A wiring is class I, and has a compeletely different set of rules about how it is run in the house.
