Weighted PF = Total kW / Total kVA without diversity? Compute:
(if loads are independent, DF ~1.2) But here, conveyor and HVAC may run together → use 1.1. Adjusted MD_kW = ( 55.31 / 1.1 = 50.28 , kW) maximum demand calculation 3 phase
If welder connected to L1‑L2, and conveyor on L2‑L3, the peak phase might be L2. For final design, balance loads. Weighted PF = Total kW / Total kVA without diversity
