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?

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
