Small Flat re-wire

[combilau]

Going to re-wire a small flat,

at the moment they have 24 of these 12v small downlights, on 8 transformers stuffed in trunking. What would be a better way of doing it is there a transformer that will do like 12 of them? Also does it have to have smoke detectors?(Reason being another big firm who priced for the job didnt price forthem)

Also found this on another job it looks likes its been poorly made of or altered?? (also not fixed to the wall lol)

Simply use GU10s instead.
Without checking any regs it will almost certainly need smoke detectors if it's a flat in a block, possibly even wired into the system for the main block, depending on the layout.

Yes that's a resourceful way of earthing an MI sheath...

Just re-read - when you say 'small' downlights, how small are we talking about?
There may be some kind of LED replacement available.

well what you have there in the pic is a pyro ....glanded (without a banjo i might add)....seem to have just used a BS951 bonding clamp to earth the sheath of the pyro...which acts as the cables CPC....and you say it isn`t clipped or secured...thats a (2) for a start....as for the trannys....whats the rating of them?....can they cope with running 4 lamps each?....or are they cutting out....due to thermal overload?....

Thats the one's i mean, yes they are running fine off the 8 transformers i just want a better way to install them as the tranformers have to go outside the room (holes to small)

So you would just leave the pyro as it is and just fix it to the wall?

I was taught that smokes are required on a rewire.

i believe it's the case that smokes are required by building regs during "material alteration" and many argue that a rewire is indeed material alteration.

Frankly, I think any owner who does not take the opportunity to have smokes installed on a rewire when the extra cost is small is stupid. Smoke alarms save lives. Simples.

Ye ive always put them in, i just wasnt sure why the other company left them off the price thats all. Any ideas on the lights?

We should have a "How not to do" photo album on the forum
That abomination that has been made to the Pyro could definitely merit a slot

Haha you should see the rest of the flat ill upload some later the main bonding was hanging out the board lol, sockets above cookers just to mention a couple

Maybe a bit more cable and a few more joints, but what about running an individual flex to each light and joining them in a enclosure with the tranny's in?

With LEDs you'd need less power so a smaller transformer, which might fit in a double 47mm backbox behind a blanking plate.
