Cable calculation

[NozSpark]

Sorry it’s 4 chargers

4 x 32amps

So... you'll have a 3 phase supply supplying 1 phase @ 64A and 2 phases at 32A.... unless you're adding something else then do your calculations to that

it is in a duct under ground with 5 other SWA 

Also, don't forget to add the grouping factor for your cable, if all 6 cables are in the one duct.
