About 2 months ago I installed 2 sets of low voltage downlights in 2 completely seperate locations. One set consists of 9 transformers and lights and the other set has 6 transformers and lights. i.e. Each light has its own individual transformer. I purchased the transformers (and lights/lamps) from Screwfix. They are rated 20-60W/VA, Inductive Load Compatible, 1.5Kw Surge Protected, Dimmable, Overload & Short Circuit Protected, Soft Start etc. The lamps are 12V 50W MR16 halogen
Since I installed them, I have had 9 transformers fail, 1 in the 9 set installation and 8 in the 6 set installation. (3 transformers that I replaced have failed again.)
All connections are tight.
I have not extended the low voltage output leads (20cm)
The transformers are not located above the lights and are well ventilated.
The Primary and Secondary wiring does not cross each other.
When the transformers fail, it is always just when the lights are switched on. i.e. During the initial in-rush. The 6amp MCB always trips in the relevant CU, like when a lamp/bulb blows but this time the lamps are always OK, it's the transformer that's blown up! Any ideas please? I'm fed-up of crawling around in lofts changing transformers.
Both Screwfix and the manufactures say they have no knowledge of a quality problem with these particular transformers.
Thanks in anticipation.
