Here is a dilemma. The electrician in my village isn't so much internet savvy as I guess(and I am not electrical expert) so I am asking this question here on his behalf. It's just similar to another question asked on stack exchange, but as I am novice in electricity, I am attaching the images also
Problem : We have a motor with this specification which is in star delta configuration. When we start in star it's ampere reads around 4, and when in delta it goes up to 30 ampere and then mcb cuts the power after 6-10 seconds.
It is a 15 hp motor. In the below image is the panel . The lower part of the panel is for this motor.
Interestingly we have another motor in star delta configuration(upper part of panel) which works fine. It's of different hp.
