what's tripping, your overcurrent or overload? Does the load require a softstart scheme? Are you hooked into inadequate supply?Is there any way to reduce the starting current of a motor since it will cause trip/blackout during start? The start configuration for the motor is direct-on-line (DOL).Need suggestion.Thanks!

I don't want to sound like a grumpy old guy but a 390amp motor is an expensive professional device and the way it is started, wired, safely fused and run should all have been handled by a properly trained professional.I just got the datasheet from the supplier. The starting current of the motor is high. 390A. The start configuration of the motor is DOL. So, is there any way that I can reduce it? By the way, is there any effect to the motor if the starting current is high?
can you please explain this bit more, if possible. thanks..You can momentarily switch in a power resistor or inductor in series with the motor to limit the starting current and then switch it out (short across it) when the motor has finished its start.
If you don't understand that then you should not be messing with this motor and those currents.can you please explain this bit more, if possible. thanks..
thanks for your advice mate. i m not trying to burn down a place or people... i just ask this because i thought its interesting to know. thanks anyway.If you don't understand that then you should not be messing with this motor and those currents.
See RB's post. You could easily kill yourself or someone else. Even a whole group of people or cost you company millions of US dollars in a burned down building and / or lost business.
Get someone that knows exactly what they are doing to install this motor for you. A motor of that size must cost a lot of money. It is not going to cost much more to have it installed properly.
While we have some extremely talented and helpful people on this forum. a hobby forum is no place to seek advice of this type. No one is on location to see the exact situation.
We have a saying "Penny wise and pound foolish".
It means you are trying to save a small amount of money while risking a great deal of money.
