    >I'm saying I don't think you have the necessary knowledge. And I'm not saying that PartP is a stupid idea or that it has no point. In fact, I came here to make sure that I make everything comply so that I am not wasting the time of the person who I am asking to review my work. If that means...

    >I know what you where considering doing to a type tested consumer unit. You know what I was asking /could be/ certified. Given that the the clamps are clearly not designed to be only used with a busbar I don't think that is such a massive jump. Also, given that the internals of the CU...

    >The cable that was pulled across a sharp edge of a hole in a 400 year old joist OK, but you can do damage to cable which has been installed for 20 years by doing something stupid with plumbing - surely the regs can't be expected to catch that! And you can see everywhere the cable has...

    >Sorry, but I don't think you are competent to do the design. Well, it's not a surprise, you know nothing about me. You might just as easily assert that I can't weld to a standard that would pass an MOT. Of course that can be tested after the fact too. >If you where you would know what...

    >Then anyone competent will not be willing to sign to say it meets regulations and is safe. Not all the hacks are electrical - I doubt that the electrician would case that where the the old sockets had been was filled in with concrete, or that the laminate flooring doesn't fit right, or that...

    I don't have it in front of me, I asked him to provide me with certification that the work complied with Part P (implication - and was tested as safe). What exactly are you trying to get at? Are you implying that because he didn't pull the cables thru the holes in the joists himself that...

    Bus bars and MCBs

    We used a local electrician who previously certified and PAT tested our other house when we rented it out. We did ask the council but their process seemed like overkill (plans on paper plus two visits) and was four times more expensive (apparently the rules have changed, and they are now...

    >Yes, if you have an accredited test lab :lol: So, not by a man with a box that goes beep sitting under my stairs then. So, the question I have obviously been trying not need answering. Except for eBay (which i hate because you essentially have no expectation that anything will work...

    Spark123, Yes, those, and I would return them and get the right ones if there was somewhere locally to get them. If the busbar was shortened to not reach the new breaker /could/ the unit be certified with a suitable wire making the final link? Would the whole system need certification - and...

    >What is the CSA of the wiring in the circuit? The new ring is in 4mm which I know is well over spec for 32A, but I wanted to able to run it in an insulated ceiling for another circuit. >What make is the old CU legrand new MCB is British General >You shouldn't start modifying a...

    Bus bars and MCBs

    I'm fitting a new circuit for a kitchen as I found that all sockets in the whole house were on a ring of 32Amp on cable that measures just less than 2mm :shock: Brought a new MCB from screwfix assuming that they all follow the same pattern... of course that was a stupid assumption. The...
