it wants a 4.0mm or a 6.0mm swa cable running back to the distribution board on its own 32 amp fuse or mcb and an isolation switch on the compressor end. price depends on length of cable and an available spare way in the dbi bought a 300 litre sip twin motor air compressor its single phase but is 32 amp , i literally no nothing about electronics. i will be renting a unit next week and am wondering what the electrician will need to set it up and will it be a big job?
