so, this would essentially be the jist of 285.12(C)......
C) Connection Between Conductors. A TVSS shall be permitted to be connected between any two conductors — ungrounded conductor(s), grounded conductor, grounding conductor. The grounded conductor and the grounding conductor shall be interconnected only by the normal operation of the TVSS during a surge
correct me if i am wrong here, according to this there should be , at least for 1 ph panels, TVSS w/ a third white wire,
or a TVSS with a third white, and forth green ?
