[QUOTE="Ardet R, post: 483862, member: 30040"] The correction factors you have applied are correct for a cable installed on a surface, installation method C, but you say in the post above the cable is buried which is installation method D. The Zs value given is for a type B 32A breaker but you state a type C 32A breaker. Could you show your working for the calculation of volt drop and R1+R2 as they do not seem to match up with the figures given for cross sectional area, length and volt drop mV/A/m.. [/QUOTE]
