Hi
Im going to be running power to my new garage and want to size cable large enough to run a small welding set rated at 140 amp
The run of swa from the house to garage is 100m, and if i size that at 140amp it comes out at 70mm cable!! But the welding set is a 13a 3 pin plug type, and even manufacturers say you can run it off a 2.5mm extension lead up to 25m long, so should i actually size it off the mcb it will be feeding (20amp) as that comes in at 10mm, or could i even get away with 6mm? As 90% of time all it will be powering is lights
