What happens instead of using 3 phase, if we give loop of single phase to all three phases ??..

If the supply system was 3 phase with neutral the single-
phase consumers [lighting, single-phase motors and so on]
could work [you have to check the other two phase are
disconnected at first].The current on the remaining phase
will rise since all load will stay on this single phase [it
depends on how was the load distributed per phase]. The
three-phase motor will not work at all-no start- no current
for ungrounded stator winding and high current for grounded
one].

If the supply system was 3 phases without neutral nothing
would work [you supply one-phase without return through
neutral].
