Hi all An old friend is trying to set up 4 1000W lights. He has a 25A (at 220 V) contactor wired in a circuit with a 32 A breaker and with 6mm2 section cable. He has a fair bit of 1.5mm2 section cable kicking about, would that cable be alright for wiring the lamp to the ballast and the ballast to circuit with the contactor and the 6mm2 cable? I have had 600W running on 1.5mm2 cable for a very long time without anywires even getting warm or any other issues, though i wonder if itd be a tad tight for 1000W. Thanks in advance.
