transformers/dimmer

[Zaffy]

My dimmer switch servicing six 12volt MR16 went. Pushed it in and nothing happened, no click. Replaced it with new component. Stil did not work. Replaced the two transformers. Still does not work. Any advice/tips before I call in an electrician?

zaffy, what wattage is the dimmer, and what's the VA of the transformers?

Try replacing with a normal light switch.

An electrician would be my first point of call though

Transformer VA 35-105W

Richmond lighting 230 v dimmer component 500W 400VA

There are two transformers for 6 12 volt downlights.

I forgot to say it is a double dimmer the other half of the dimmer works fine and serves an ordinary lightbulb.

assuming that each lamp is 50watts, then you are loading a 105 watt tranny with 150watts a 35-105 tranny should be 1 tranny for 1 downlight.

I installed a two gang dimmer yesterday. One side worked fine and the other didn't. After deciding it was faulty, being a qualified sparks I decided to poke it with my (1000v insulated vde) screwdriver.
This is no word of a lie. It sparked, made a popping noise and caught fire. It looked like magnesium burning. I turned it off put a 2g switch on and I'll be going back in the week to replace it.

Call a qualified sparks!!

Have you changed the lamps in the fittings recently?

Each light is 20watt

So the lamps in them now are 20 watt each? How lamps does 1 transformer feed?

Three each, I presume.
