Different system, there is no 110 here, only 240v and 415v


As for Sylvia, yes you would be charged for the consumption.
this situation would work similarly to a 3 phase delta type load

The load, even unbalanced as it is, would be a certain VA at 415v -
across the 2 phases

How the meter responds to power factor of the load in question would
be the only thing that may or may not register less KWH than actually
used, but this should be to the same degree as the same load in a
single phase install.


IF this wasn't the case, we would have big problems regarding billing
on installs having both single and 3 phase loads on the same meters in
3 phase premises.
