About my kitchen cabinet downlights...

Electrician has left me with a new bit of twin and earth sticking out the wall (which runs from an FCU)...

...one of these (pre-wired 240 to 12V transformer):

...and two of these (pre-wired 20W 12v downlight):

So, how do I connect them up?!! I'm assuming it's a 20A junction box off the twin and earth, transformer into junction box, then another junction box off the other side of the transformer for the two sets of lamp connections. and where can I hide all this?

He's coming back next week to connect circuit back into the mains (I'm not going to be electrocuting myself), and I've promised that I'll have acomplished this rather simple task in the meantime. (I was having the kitchen plastered between his visits, otherwise he would have done the lot).

what a thicko I am, so apologies!

cheers.

see //www.diynot.com/wiki/electrics:lighting:single_way_lighting & treat your fcu as switched live & neutral( I presume it is a switched fcu) then connect the transformer to that & the lamps to the transformer,the output of which becomes your switched live & neutral to the lamps. You should fix any j/bs under the cupboards along with the transformer & light fittings,but a choc box would be easier than 20A junction boxes.

thanks for that.

so, as the transformer is pre-wired at both sides, i use 2 junction boxes (or 2 choc boxes)? and there's no earth on the transformer, so do i just terminate the one from the FCU in the JB?

and to be really thick, i can run two lamps off the single JB?

cheers

Yes as long as your transformer is rated suitably for 2 lamps
