Overcurrent Protection

Your condition is not plenty. none can reply it! pls complete it. I hope to help you on it.

Please clarify what are the additional information that you need? I am looking for general guidelines.

You need to show the Single Line diagram to know the load distribution below. To put it broadly you would first require the total load this feeder feeds. Also are there large size motors etc. After a simple load claulation you need to then co-ordinate with other protection downstream and upstream to set this overlaod protection.It is a wee bit long story! Btw check NEC for guidelines to set overload protection for MCCs based on motor loads.

for esxample, what is the power? at least you should point out this! and whats load
