possible to replace a NSB06 fuse cartridge with a NSB16?

When you applied for Building Regulations approval, what did you say would be the way that the electrical work would comply with P1, and how did you manage to get a Building Regulations completion certificate given what was actually done?
 
i did not sort any of that out i left it to the builders. how would i even know how to comply with p1 watever it is. all i knw it there was a double socket in there when they finished. maybe i will call them on monday to inquire about this p1
 
My advice is to get the builder to put right the ****-up he made of the electrics.

It was his legal responsibility to do it properly, and he did not, and he falsified official documents to say that he did do it properly.
 
If you" dont know how to comply with P1 or whatever" then you shouldnt be touching your electrics, just like the "joiner" shouldnt have. I would hope there are 6 wires coming into your socket for you to spur from

If you didnt have two great RSJ's craned into the house to support the floor of the loft conversion then you dont have a certificate from the building officer. You are not allowed to use the joists or strengthen them for a loft conversion any more

You should have at least 2 certificates from the loft extension, one from building regs and one for the electrics. If either is missing your going to have a lot of fun when you come to sell the house

I think you need to have a word with the joiner

are you quite sure about that? Surely it is up to the structural engineer to specify what is required :?: :?
 
Having 3 years ago had ours done, the regs call for the load to be on the walls of the house and not on the existing joists. ie the new floor is above the joists. Its normally done by inserting 2 Steels across the house and putting 6x2' between them on hangers and then boarding with 1 hour fire resistant

Its a pain as you loose at least 7" of height in the loft and getting the 2 steels in is a pain. I suppose it could also be done on a small loft by new 6x2's across the house from wall to wall

The old way of adding extra joists between the old ones is no longer allowed. The new floor must be independent of the old ceiling. I was told by the architect, and the builders that this was a legal requirment and the buiding inspector had the floor up to check it

Our electrics were fun. OK the wiring was fine, but the sparky? wired an rcd up wrong (neutral on the wrong bus). Whats more he didnt spot it on testing, nor did the guy who come in and tested/certified it. (I didnt see a tester, just a socket tester). Fortunately I have a megger and know how to use it so spotted the RCD test failure pretty easily and very easy to fix. Our EIC is interesting, filled out with no test results!, but the BCO was happy with it !!!!!
 
im pretty sure i know what im doing with the spur, find a nearby socket with 2 wires goin in, test for resistance, if its ok 2 go feed 2.5 cable to my new socket
You need to be more sure than "pretty sure". :lol:

Seriously though, while it is not a particularly big or difficult job (hopefully...) it is seriously concerning that whoever did the electrics on this extension put a socket on the end of the lighting circuit! It really does show a very poor understanding of electrical work.

Best bet would be to get the builder (or whoever ran the project) to come out and sort it properly. I'm guessing that he was paid for putting a socket in the attic? He needs to come round and sort it out - now!

Well, there's some finer points to it, but yes, that will likely be a lot better than what you have now. However, if you're going to that amount of effort, it may be worth seriously considering breaking into the existing ring final and taking it to multiple sockets in the loft. After all, is a single 2 or 3 gang socket really adequate when you've got a computer, games console, TV, fish tank, lights, heaters...

BTW, it's unlikely to be a sub-£100 job for an electrician, but if you aren't fully confident in your abilities than it's still a worthwhile cost for peace if mind, IMO.
 
ok thanks guys, im gonna have a crack at it anyway it will be good to know i can do it myself in the future, just make sure i follow everthing iv be told and cut the power at the fuse box!

also im not sticking up for the man who did the electrics but he didnt install anything new just left what was already there
