Cable table which column to use

Baldyhugh
Hi


Im currently doing a bit of circuit design and am a bit rusty. I’m planning to use a 3 core swa for a single phase circuit. Do I choose the 2core cable single phase column in The regs book current capacity tables even though im using a three core cable or the three or four core cable column? Some of the tables show a little asterix denoting ‘with or without a protective conductor’ which would help in my instance, however table 4d4a doesn’t show this. 

Thanks in advance

    Yes, and of course these tables are for continuous operation in an ambient temperature of 30C so I would say for the vast majority of installations you have an appropriate inherent safety margin.
