Can someone explain a couple of things to me on this nameplate info for a convection oven:
TOTAL KW = 5.5KW
208, 240v 3 Phase Loading - KW per Phase:
L1-L2 = 2.5, L2-L3 = 0 , L1-L3 = 3Kw
Nominal Amps per line wire:
3 Phase 208 Volt
L1 =23, L2= 10, L3=12
Why is there unbalanced loads per phase and how would you choose a cable wire size with all the different amperages? Would you base cable wire size on the largest - 23 amps? Would you use a 3 pole 30 amp breaker?
