You're running a high-draw load and the cable you grabbed off the shelf isn't rated for it. This 6 AWG oxygen-free copper cable handles 55–75 amps depending on your insulation setup, and the 8.5mm diameter gives you room to work in tight conduit runs without cramping. You get a full 30m roll in black, so you cut to length and stop hunting for another spool mid-job. OFC means lower resistance and less heat build-up over long runs – the difference between a cable that lasts and one you're replacing in two years
