Even if they have the grounding pin on the 120V side, it's unlikely that it's bonded to the secondary like the TMCC command base transformer. I have some alarm system AC transformers that have the ground pin, but it goes nowhere but inside. I surmise, though I can't prove it, it's some sort of faraday shield between the primary and secondary windings.
