we have 3 phase 4 wire supply 230/415 V.AC and our
distribution is single phase or we have all single phase
220 v,ac operated appliances. and noted the current with
help of clamp meter Red to N = 20 Amps. Yellow to N = 45Amps
and Blue to N = 30 Amps ( total is 95 Amps ) what will be
neutral current on the main .
