shimble Posted August 7, 2007 Share Posted August 7, 2007 when installing a 12 volt lighting system with transformers how many transformers can be connected to each disjonter; ie if i have a transformerwith five 12v spots does this count as the maximum number of lights for each disjoncter or can i add other transformers with 12v lights to the same circut if so how do i calculate the maximum number of 12v lights to each disjonter line?

Nick Trollope Posted August 8, 2007 Share Posted August 8, 2007 Sensible max is 5 (transformers) per DD (16A), legal max is 8. Max number of lights depends on rating of each transformer, but 25 (or 40) in your example.Even if you use 50W 12V halogens (and would you?) in each fitting, then 25 of them would equate to 1250W - easily within the 16A DD rating. You would need 250VA transformers for each circuit - rare and expensive. Most are rated at 150VA (3 x 50W spots or 5 x 20W) or 60VA (3 x 20W)But, for the sake of our children, use LED bulbs!

One wholesaler about £5.60 each inc VAT. How about France where CAN they be found and at what price?Paul Link to comment Share on other sites More sharing options...
