I have a small building to design. The main supply is from another building (existing) which is 3 phase and 63A protection (not sure about it). It is 7 way and 3 are spare. L1 is 96A, L2 is 54A and L3 is 84A. I am looking forward to use L2. But the new building have a load of 82.1A and probably require 100A protection. I think L2 is not big enough for the new one. Can some one fire any idea weather to get a new 3 phase line or use one of 3 spare and distribute the load across. Can existing building (3 phase 63 A) enough to take this new load?

Any one have any thought about it?

Have you taken diversity into account?
