Cable sizing for a 3 phase Chiller

Former Community Member
Former Community Member
I have a question regarding the supply to a 3 phase no neutral Chiller.


The details stamped on the side of the chiller are - 400v / 50hz / 3ph / 386 max amps.


Am I right in thinking as 386amps is the max load shared across the 3 phases then the load per phase is 386\\1.732 (square root of 3) which makes it 223amps per phase so I have sized the SWA feeding this machine at 70mm 3 core with separate 35mm CPC.


Hope to get a unbiased  opinion from other knowledgeable electricians.


Thanks
