Im looking to run in 2 16a 3 phase supplies, 25m long.
From what I can understand 1.5mm SWA is suitable up to 23A (table 4e4a, clipped direct)
1.5mm cable has a volt drop of 27mV/A/M = 10,800mV - 10.8v (table 4e4b, 3 Phase AC), Less than 5%.
So why do I see many people talking of 4mm installs?
I must be missing something?
