Hi all.... I’m changing a standard 2 gang socket over to a 2 gang switched USB charger socket. I’ve taken plastic socket off and met with the wiring setup in Pic attached. Obviously black/blue neutral and red/brown live. However, can anyone advise on what I do with the earth terminal? I have modern wiring in the kitchen and it’s far simpler with updated wiring. Thanks in advance. Picture of wiring abs the socket I intend to fit attached.
