Why I get only one phase reading current while rest are zero

[SoonIWill]

Hi

I have UPS 50KVA and the inverter output AC voltage is feeding a distribution panel 120/208 V 4 wires when I check UPS display it shows me that output current which is the distribution panel phases as followings phase one = 30A while Phase 2 = 0A and phase 3 = 0A is this a problem !? Shall we work to make the load almost shared on all 3 phases not only one !?

The only way to really tell is take an actual amp probe and check it that way. I wouldn’t always depend on your UPS display. You do need a more balanced load and it’s odd that all loads are on 1 phase. Good luck and welcome to the forum
