what are doing the duall connetion in tree phase 10hp or etc motor with circuit diagram ..

Answer / payalbhendarkar

I think you are saying about DOL connection for 3phase, 10hp motor. DOL means direct online starter. as per calculation for 10 HP, Power= VI/ (ROOT 3 X COS PHI) where V is three phase voltage, I is current , P-is power cos phi is 0.8 (for inductive load). Cuurrent will be 13AMP.
