Hi all,
i want to wire up my shed (a double socket, one socket for the freezer, the other for the occasional lawn mower, pressure washer etc. and a light). The house is RCD protected at the CU.
I have been told, i can start from the living room socket (feed), to wire up a RCD spur to the socket and from there with a minimum of 2.5mm twin and earth (which is going to be an outdoor cable, in conduit) to the shed.
I would additionally (without being told) install a neon control switch between the feeding socket and the RCD spur to be able to isolate the shed without needing to switch off all the downstairs sockets.
My question: Do i need the rcd spur considering the living room socket itself is rcd protected? I am afraid the rcd "might" trip at some point and the freezer in the shed will be off without me realising it; as well as, what is the situation when a rcd spur is wired up in a rcd protected circle (or ring?)
Would a MCB on the CU be sufficient and safer considering the rcd, to my knowledge, provides no protection to overheating? (this option would mean a lot more work, but if it comes down to safety i don't mind)
As you can possibly tell, i am not an electrician, but have a good understanding of technical matters and a "certain amount" of common sense . I am also aware, Electrics is not a playground!!!!!
The above terms (MCB,CU) are discovered through my own research in the internet.
Any reply would be greatly appreciated and pretty please, try not to use electricians jargon
Thank you all in advance and kind regards
