How to calculate the additional load can be add to existing system?
Hi all, I am not in the electrical field but I am curious about this matter so that is why I am going to ask. I have a 3-phase switchboard using 2500A TP 50kA 3 sec ACB as a main breaker to cater a design load of 1052kW of maximum demand. The system already run for 2 years, and now I am going to add 2 nos of 90kW pump into the system. Here the normal run reading for the system: IL1=1137A, IL2=1222A, IL3=1180A, VL1=411.3V, VL2=410.7V, VL3=411.6V. The question, can the existing system able to cater the additional 180kW loads? Please help me.
