Default three Romex sets in ceiling box

Medium voltage is typically single phase when it hits the distribution
transformer, either as single ended wye distribution (one hot and one
neutral) or delta distribution (2 hots) but that is still single phase
if the 3d phase is not present on the hubs. The output of the
transformer is also single phase that gets divided with a center tap.
That is how professionals describe it, no matter what contortions
people go through to explain it to morons.

Exactly!

I have a Siemens breaker panel and a Generac ATS, both labeled single phase.Â* Only a moron would claim it's 2-phase.
