It doesn't matter, since the transformer goes before anything else.
It operates at line voltage, and in Gunner's case at a constant 60 Hz.

It does matter, a set of transformers can most certainly come after a
RPC, if you only have buck transformers large enough to handle the three
phase current, not the single phase current.
