I am installing a heated towel rail in a shower room and need to wire in an FCU off the exisitng ring main to power it. I have the floor removed and can access the 2.5mm ring circuit. I want to break this circuit to add the FCU (in the correct zone).
I have read a lot of the threads on crimping and plan to buy a suitable ratchet crimping tool for fully insulated blocks. (blue crimp for 2.5mm Phase, Neutral, red crimp for 1.5mm Earth, heat shrink after)
My question is, as i am breaking the original ring circuit, and I can't use Junction Boxes in what will become inaccessible, one side of each crimp will have two 2.5mm cores going into it, the other will have one. Do I still use the blue crimps for the 2.5mm, or should I use yellow crimps suitable for 6mm?
Is it even allowable to have two cores going into one crimp?
(Additional earth bonding will be performed as well)
Thanks in advance
