What type of cable is table 4d2a for?

Holly Edwards

Hi I'm just trying to get my head around some of the tables in bs7671. Can anyone help me with an example of what type of cable TABLE 4D2A – Multicore 70 °C thermoplastic insulated and thermoplastic sheathed cables, non-armoured (COPPER CONDUCTORS) might be. All the others I know types and utilisations for them but this one I just can't seem to fathom what type of cable it's for.... Thanks

    4D2A is for all ordinary PVC/PVC cables (flexes are slightly different and need additional factors or just use their own tables, 4F1). Traditionally 4D2 was for all shapes of cables, but some "flat" types (i.e. T&E) now have their own table 4D5 which gives slightly higher ratings for some installation methods) - so 4D2 now is mostly for round cables plus flat ones where the installation method isn't covered by 4D5.
