Hello All, I had a friend round (who is an electrician) to help me change 6 x 1 gang plugs into 2 gang plugs. During the work they managed to slice through my main power ring (i think) twice in 2 different rooms!! They have connected the wires back together using red crimps and a ratchet crimping tool. Then wrapping in electrical tape. Obviously this makes me a little paranoid as to whether this is actually safe. My questions to you all here.. is it safe to use red crimps for the ring mains on a house? Ive been reading crimps are the most secure way to join connections but i get confused with the "current rating" against each colour of crimp. Can someone explain this to me? I also read that junction boxes should be used, though there appears to be man debates over crimps vs boxes.. I am not living in my house yet so i can afford to wait and get this resolved the correct way. I ideally do not want to be rewiring the entire house. Im not one of these il just pay someone and they will fix it kind of guys. I like to know a bit about it all to give me some piece of mind that what has been done is safe and acceptable.
