Whats TVSS?

edit... just looked it up and basically it surge protection?

Supposedly the day before(maybe day of) the grounded phase there was an issue with an undersized neutral of a subpanel which was # 10 and they measured 65 amps.. the neutral blew and subsquently damaged the ups of the computer rooms.

Could the phase to ground have caused this and not the neutral?
