4.4.2 How to connect single phase load
The method of connection of 3 phase 4 wire single phase load is as follows.
The allowable current limit shall not exceed the values in the following table.
Conditions of Load Allowable Current Limit Conditions
In case of three phases
Allowable current limit up to
the rated current.
Adjust the load capacity so
that each current value of
each phase (U,V,W) may not
be more unbalanced than
50%.

current value
50Hz/200V 107A
60Hz/220V 118A
50Hz/380V 56.2A
50Hz/400V 53.4A
60Hz/440V 59.0A
Allowable current limit up to
the rate current.
But voltage change becomes
larger due to the unbalance
of each phase.
In case of three phases
Allowable current limit up to
the rated current.
Adjust the load capacity, so
that each current value of
each phase (U,V,W) may not
be more unbalanced than
50%.
