    SWA - earthing the steel wire?

    Hi I’m new to the forum & just a DIY’er! I’m running a 15m length of 2.5mm 3 core (twin & earth) SWA to our decking at the back of the garden for a double socket. Must the steel wire armour be earthed using the banjo or is the CPC core sufficient? Thanks in advance! J
