Afternoon, i have a ring doorbell camera which is battery operated, but the battery can be charged by a ring transformer plugged into a socket. I have a single socket unused nearby and to save keep taking the door bell off and keep charging it up am buying the transformer from ring. The socket is supplied from a spur and spur supplied from a junction box into the ring main. The socket is of course indoors and the bell / camera on an outside wall protected from rain pretty much. Should I or do I need to fit a fused switch to the spur cable to protect it up to the socket which the transformer will be plugged into. Many thanks for advice.
