We have two Al.busbars each of size 125mm*10 mm connected in
parallel.To increase the current rating ,can we connect
third busbar of size 100mm*10mm in parallel to existing two
busbars?In my opinion ,if we connect busbars of different
sizes in parallel,then the busbar of lowest size will take
much current.So this type of paralleling should be avoided
.Am I correct?

Answer Posted / vineet kumar srivastava

in this parallel operation every bus bar will take equal
current so if this rating is equal to running current (after
divided same load), can provide it.
