Ring Mains question
Discussion
I am replacing my complete upstairs ring main, to move sockets about and also get them off the skirting board on to the wall itself at the same time.
Correct me if I am wrong but 2.5mm T&E for the ring main is what I believe to be correct for an average sized house (non commercial) ring main. My question relates to any spurs, is 4.00mm needed for any spurs or will a single 2.5mm T&E be ok for those too.
I know what the two spurs will be used for and also know they can easily be catered for by 2.5mm T&E current draw wise. But in the interest of doing this properly which is the right cable to use, 2.5mm or 4.0mm T&E?
Many thanks in advance for any input

Bloody hell, 3 helpful responses to an electrical question, and no one has suggested OP needs to get a professional in!
Good point, well made I may or may not be having the alarm mains supplied box upstairs, since that hasn't been established yet I am going to get on with putting in the ring main.
If when that decision has been made I need a supply I will stick a spur in, needless to say it will not be drawing much current but was trying to do it the right way, sounds like 2.5mm will be ok.
Make sense?

How are you going to test it and connect to your consumer unit?
Presumably using a qualified electrician through a 3rd Party Accreditation scheme, such as NAPIT's?https://www.napit.org.uk/schemes/third-party-certi...
Also, having the alarm panel upstairs seems like a good idea to me, much harder to find!

But you haven't actually found someone yet?

I'm not the OP, but this route rarely gets mentioned in these threads......
And yes he should already be talking to them already, but if the works are not yet covered up, it should be a non-issue.
The NICEIC explicitly forbids the signing off of a 3rd parties work, so that rules out a good percentage of registered sparks.....And yes he should already be talking to them already, but if the works are not yet covered up, it should be a non-issue.

I am currently chasing in all the ring main points with conduit where required so all the cable can be run through to all the sockets. When that is finished the electrician will come back to connect the wires and test everything.
There is an existing wired alarm (as opposed to wireless) already fitted upstair with all the cables run to it. The box will be replaced by a qualified alarm fitter and the position of it may move a bit but would rather not move it to downstairs and have to run all new cables as there is nothing wrong with the old ones.
I hope this plan does not upset any over sensitive professionals

he property has had a large extension which included a new consumer unit and all new wiring fitted which is already working. All the original wiring elswhere in the house is now disconnected and redundant. All this work has been done by a qualified electrician.
