How to calculate busbar size & what is the procedure we
make for determine that?

Answer

Depending on the maximum load current the busbar size will
be determined. Usually for copper it is taken as 2 to 4 Amps
per square mm and for alluminium it is taken as 1 to 2 Amps
per sqmm.
The normal availability and design of the busbars is
25*5mm,50*5mm,50*10mm,60*10mm.

Question { 7295 }

how to connect from a line-to-line connection to a line-to-
neutral connection?

Answer

If it is 3ph and star connected, then connect the star point
to neutral. If it is any resistive circuit having connected
to 2phases, then the mid point of the circuit is connected
to neutral and the other two ends will be connected to
phase, which forms a line to neutral connection.
One more option is that, the line to neutral voltage is made
similar to the line to line voltage than it can be connected.
