A balanced Y-connected load with 3 + j5 Ω/ph (L-N) is connected in parallel with a balanced Δ-connected load with 12 + j15 Ω/ph (L-L). Determine the combined total equivalent Y-connected impedance per phase. If these loads were powered by a Y-connected 2400 V_LL generator, determine the current drawn from the generator lines.
