Loft conversion circuits

[bigbro]

Hi all,

Advice please...

I am considering having my loft converted but only want to pay for the shell and do the rest myself. Times are hard!!!

I have an old cu that is wire fuse. Will i need to change the cu box and have all the current circuits tested or is there a way to have a secondary cu from my old supply. the loft will need ring, lighting, smoke alarm on three floors to include two current levels and a shower circuit.

I realise that i will pay to have the testing done but really need to keep costs down so the wiring to the cu area i can do.

Any advice greatly received.

Brendan

So ''What's Changed'' then?? I don't believe anything has changed in this respect, apart from the ill trained, ill experienced, and don't give a ---- electricians that are flooding the industry!!

You have had all the reasoning you should need over 9 pages and 89 posts, if you can't or don't want to accept that reasoning, that's fine too!!

Now, if wanting to keep standards as high as one is used too, is being a Wyatt Warp as you put it, that's more than fine with me, there's nothing narrow minded about that, far from it in fact!! I can't honestly see what your trying to defend here, unless you too, seriously think that bunging a 5+ way CU in a loft bedroom is the right way of doing things and serves the best interests of the overall installation?? If so, ...go for it!! ...But you'll Not convince me otherwise...

ive just looked at all the posts and not one has any reasoning as to why it would be wrong yourself included
its a simple question that no one seems to be able to answer?
this leads me to think that there is no genuine reason to your argument?
only your opinion as i said posts back.

if i have missed the reason please fill in the blanks

Sorry, wrong. The loft will need an installation cert which can only be issued by the person that carries out the "construction", ie, installs the cables.


we all know certs are issued for someone elses work and it is wrong, same as a bent MOT!

I think this started about a DIY loft conversion? My conversion is almost complete and you need all the works, not only electrical to be passed by building control.

I recommend a PIR carried out on the installation before any works are carried out. 3036 protection is the reason why, or at least ask an electrician to give some advice. Work in the loft will mean all the main bonding will need to be upgraded.

Why extend circuits into a loft if its easy enough to run a sub main to supply the loft area c/u?

Rather keep it seperate instead of mixing new and old cables. In the event of a rewire on an old installation the loft is on its own circuit. i wouldnt want to loose lighting in the loft area cus of a fault on another circuit. Saying that i have provision for emergency in my loft.

p.s, Bob Saunders is a top man. He assessed me yrs ago as i remember when the area was an engineer short. I remember he was very helpfully after on the phone with an issue i had. Another top man is Mr Cable as seen on the tv!! (forgot his 1st name, works in head office).

This is a windup, right? Ha-ha.

And your the type of electrician that would actually advise a client to do an installation in the loft this way... Rather than advise him at the very least, to upgrade his CU so you could do a properly conducted installation to the loft bedroom... Geezus!!!

As for your PS, ... Top men?? They both work for Scam providers, and one has even sold his sole to them....haha!! I suppose they advised you to run sub-mains to extensions and loft conversions in small houses too, rather than upgrading the existing CU to accommodate the additions. Top Men indeed!! lol!!!

I'm hoping it's all a wind-up, It's bloody sad if it isn't!! lol!!

Steve there is nothing technically wrong with installing a CU in a loft. But common sense tells you that the easiest way would be to upgrade the current CU to incorparate loft circuits or Put new CU next to current CU. In this scenario if you wgere to put a CU in the loft the sub main would have to be 16mm to supply shower, sockets and lights. Now if anybody thinks installing 16mm cable is easier than sending a 10mm, 2.5mm and 1.5mm cable down then il take my hats off to them. Its doesn't need a seperate CU in the loft.

Twice u mention upgrade of the CU, why? Whats that got to do with a loft conversion?

Anyway mine has an onsuite with an electric shower should the main shower off the boiler break down. That means a radial circuit off the main board anyway, plus the loft board and its secondary circuits easier 2 install!!:teeth_smile:

Maybe things are done different where u r? :45:

 

[41steve]

Sorry, sub-main off 40A RCBO off the main board. Electric shower might be required anyway?

The magnificent Mr Tony Cable,he of Niceic and Bullcrap consumer programmes had the audacity to come on a forum at one time,i cant remember if it was this one or another

I asked him to attempt to justify the reasons why they used the QS system for domestic work,with the result that 3 day trained Eric the half spark can now employ countless "never held a screwdriver" co workers to carry out installation work,so long as the one numpty signes the piece of paper


The famous TC was never in town again and likely never will be
plonker of the first class

That's the guy that ''Sold his soul'' to the NIC ....A real Top Guy , for the right price of course!! lol!!!

Frankly, you don't seem to be too sure of what you have in your own home!! lol!!!

Sounds like a truly professional job!!!! ...lol!! You seem to be proud of it too, Amazing!! lol!!

No, but even the Chinese sparks have more sense than that!!

Good luck to you!! I'm just not good with bricks or walls!!

cheers,me neither!!

 

[41steve]

Why? Radial of a 40A RCBO to a board in the loft and secondary circuits? I would of had to run a radial for the shower anyway. Its easier what i have done with a CU and in the loft and i havent had to mess with the existing circuits, simples!!!

p.s, ive been to Shanghi, think in 1987. Do they still use bamboo for scaffold? Good food there. :45:
