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

    Thanks for your replies, 


    On another note, in debating whether to use SWA or hi-tuff for a job I’m currently designing. As hi-tuff( that’s what it’s called in this area, I know others have different names for it) is basically pvc insulated cores with a tougher outer sheath, would table 4D2A be the correct one to use?


    Thanks




    Doncaster cables told me to use table 4E4A for their Tuff sheathed cable, and Draka cables, I seem to recall, told me they no longer do what was their Hi-Tuff cable, but call them and confirm.
