SY Cabling - Current Carrying Capacity

ElectricalCuriousity

Often I am finding SY used for the permanent fixed wiring of installations for circuits like Air Conditioning and Sockets. Apart from the obvious with SY Cable not permitted as such for these circuits as per BS 7671, Is there a specific current carrying capacity table for SY? This is because sometimes on EICR's we are finding SY being too small for the load but cannot always find the exact table/document to back this up.

Thanks

    SY is not recommended if the braid is the only earth, but if you use it where it is not critical, where you could have used arctic flex or something its not really an issue 4D2a is probably a good place to start for similar situations.
