BICC or BS7671 comply for design

Anthony Sullivan
Hello IET guys 


I have a problem where a cable installed on site doesn't comply to Bs7671 current  carrying capacity for underground cable reference method D 


the engineer who design the cable used amtech and data from bicc with reference method 110. 


Dose bicc comply? As its old data for cables install in any country from what I can see. I would have thought bs7671 design must be used?

    thanks for your help. I can see lots of the data match's. I’m just unsure on underground cables. I would have thought bs7671 has been correction factors for uk use. The cable in question is as follows 


    250a main switch to DB 400v 

    xlpe swa 

    0.03ze 

    30m: ducted 15m ladder 15m 


    the cable installed is 95m 5core swa
