Hi,
in an commercial project I need about 180-190A power @ 1-phase 120/240v.
The existing, available service is: 100A, 3-ph., 4wire.

How about if I install 45 KVA , 3-ph. dry type xfrmer (240v-120/240V, 1-ph.) thru a 90A C.B at primary.

I know that I will get 185A at secondary if I use 125A Breaker @ 240v,3ph. at primary side.

but I have 100A max available in the bldg.

what is the ratio of this configuration: getting 190A @ 240v,1ph. from 60A @ 240v,3ph. through a 45 KVA xfrmer????

To how much a 60A, 240v, 3ph through a 45KVA xfrmer can be converted
desired power: 190A @ 240v, 1ph.????
