1.5mm will run that no problem all day long. as said above . is there any need it doesnt take Einstein to look up the current carrying capacity of cableUse it @fizzy , it will be fine. Turning into a nitpicking wall **** ing competition again.....
Very useful for future ref!This is a useful chart from Square D motor controls from years back, 4hp 3kw motor @ 415v is 6.4a per phase
View attachment 320007
4HP is 3kW?
3 phase is fed by three conductors?
1kW per phase?
god help us if its anything more than a simple 3 wire load 2o minutes to wire one up and 5 days debating it get on to big heavy cables on long runs costing hundreds with heavy loads then it becomes important to critically calculate itWow - that was a lot of debate for what could have been a straightforward answer

you dont go fishing do you it was 24 inch long honest . one post answered that question on cable sizeSay's the man with about 30 million post's.......
Of course it did, but it generates good discussion for others to understand why, you know it inside out, others don't, and that's the benefit of this place, you can learn from others experience, and sometimes have a bit of craic on the way.you dont go fishing do you it was 24 inch long honest . one post answered that question on cable size
Do any of these calcs take into consideration startup current or longer leads
