[QUOTE="unphased, post: 544479, member: 6"] To be honest, I find it astonishing that you even considered a saving against a voltage drop on a cable. I'm not gonna do the maths but personally I wouldn't ever consider the running costs of some electrical equipment in terms of increasing a cable size. You should design a circuit for volt drop of course, but turning that in to a cost saving is pushing things to the realms of bizarre. When you consider the overall price of the EV charger. the cable. parts etc and add your labour on top, there is no 'saving'. The perceived saving is negligible in the extreme. Personally you ought to have used the 6mm2 on being the correct size for the job. [/QUOTE]
