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

Answer Posted / vijaykumarht

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.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
