Can you wire a 3 phase wye into 3 single phases?

Single phase power can be taken from a three phase system.

Any two legs of the three phase system, taken together, are considered to be single phase. The legs can be any of the following combinations, L1 - L2, L2 - L3 and L3 - L1. On a three phase four wire system, called a wye connection, any line to the grounded neutral is also considered single phase. L1 - N, L2 - N and L3 - N.
