Tony... when connected to the 208V supply, line-currents Ia, Ib, and Ic will be 62A, 47A, and 62A, respectively.
The values obtained are based on the following:
o The resultant load is an Unbalanced-Delta.
o At 208V, the 7.5kW heating-elements (call R1, R2, R3) will each require 6.5kW.
o At 208V, the 4.5kW heating-element (Call R4) will require 3.9kW.
o Load distribution is: R1 (6.5kW) between Line A and Line B; R2 (6.5kW) between Line B and Line C; and R3 & R4, in parallel (10.kW), between Line C and Line A.
Anyone, except PTM's, may contact me off-forum if detail is needed!
