My house has something like that; the previous owner wanted '3-phase for machine tools (I think - could have been a
compressor, or something)
in
his basement workshop, so they sold him a
pseudo-3-phase service. I
forget
the exact details of how it works, but the 3rd
phase is at 170V to
neutral,
It should be 208V - see center grounded delta online. 240 *
sin 60 degrees = 207.8 V.
