CABLE RESISTANCE EXAMPLES Max volt drop allowed is 2.5% = 6v @ 230v
1.1 Kw motor single phase on 150m of cable,
ie: on 1.1 Kw the maximum you can run is 190m, if you use 10mm.
1.1 Kw motor three phase on 150m of cable,
ie: 1.1 Kw can go up to 180m on 1.5mm cable. Therefore on 10mm it can run up to 600m.
