        "note": "For multiconductor cables 4/0 and larger, NEC 392.22(A)(1) requires them laid in a single layer with the sum of their diameters not exceeding the tray width — they cannot be stacked or bundled. So a 12-inch tray holds cables whose diameters add up to 12 inches side by side. Mixing these with smaller cables triggers the combination rule in 392.22(A)(1)(c).",
