Linking Low Voltage Downlights

[Damon]

What is your guys preferd method?

I was just gonna use 1.5mm Twin(brown cores) to link each light.

or should I t&e and connect block the earth.

I put the 230V leads of the transformer into the joint, and the 12V side straight into the fittings.

 

[Damon]

So you have a separate JB and Transformer for each light?, I have drawn it on paper like that.

 

[telectrix]

yep.1 each. if you get a tranny fail, only one light goes down. my earlier post mentioning flex was due to the trannies i have been using do not come with flex attached. those that do, wire primary cable into JB

Thanks Telectrix.....clears things up alot appreciate it.

 

[telectrix]

and you only need a 60VA tranny for 1 light, about £4 each. i prefer the trannies without leads as then i can use heat resistant flex on the 12v side. the number of burnt cables i've found on some trannies beggars belief.

What Brand Transformers have you been using?

 

[telectrix]

can't remember now, it's a while since i used any. always try to use 230v GU10s where possible, unless customer insists on ELV, i try to steer clear. nothing but problems with 12v, least of all the current drawn at such a low voltage ( approx.5A ) rarely find problems with burnt lampholders on GU10s

I've been using these for a whiles and not had 1 problem with em

Collingwood - Green 60 Transformer

so many transformers come with 0.75mm on the secondary, it's way too small.

I only ever use these.

Where do yo buy those from Pennywise?

 

[pennywise]

Get mine from Eds but most wholesalers can get them easily. The Newlec ones where made by IBL and where identical, they do a dual output ones as well.
