not strictly diy but am sure someone on here will have the know how.
am looking to calculate the volt drop on a 3 phase cable. the cable is wanted to supply a 3 phase welding (no nuetral) machine pulling 80A per phase approx. proposed run is 50 metres.
proposed cable is swa pvc 4 core 35mm (4th core as cpc). i work it out as complying but as most of my work is domestic my 3 phase calcs are a little rusty.
