Hi
I've been asked to provide a supply to a machine shop on a farm. The nearest supply is 170m away.
I'm working out the vd/a/m and I'm looking at having to install a 25mm 2 core SWA to compenate. But that is while working out the current carrying capacity of the cable at 152amps (Ref. E) or 25Kw.
However, the load isn't going to be anywhere near that: the main piece of equiptment is a mig welder at 10amps and some small hand tools. They don't even require lights.
Should I calculate the vd/a/m at the cable potential load, or can I use the expected load (closer to around 30amps) - I'm running three double sockets individually run on 2.5mm from separate 16amp breakers
Thanks for your time.
