Hi all,
We have a lighting circuit in the living room with:
6 x 12v/50W halogen downlights
1 x 400W rated dimmer (Aurora DSP400) (previous dimmer was a Hamilton 600W rated one)
1 x large "safety isolating transformer" by Trac lighting. This is a big white box next to our MCB with rating of 250VA Fuse rating T 25Amps. Output 12V AC.
The lighting was working fine for about 2 years with the Hamilton dimmer. One day, I was told that there was a noise from what seemed to be the large Trac transformer and the dimmer stopped working. Upon removal, the dimmer didn't look damaged/burnt or smell.
Replaced with the Aurora one, but this has failed in 6 days. Same deal, no burnt smell or visible damage, and also apparently a sound from the MCB vicinity (both times the missus has been present, not me).
At no point did the breaker, or RCD fail.
Any ideas on the first point of call to troubleshoot here? I was thinking of replacing the dimmer with a normal switch. I've got one, but it doesn't have an Earth on it, so was going to fix the earth to the metal socket box assuming this is ok. I'm fairly certain I can't cause any damage/make things worse doing this, but wanted to check with the experts on here what they thought?
Thanks!
