BG triple dimmer switch. First dimmer controls five lamps via three cables (two of the lamps are daisy-chained to another). Second dimmer controls three lamps, all daisy-chained). Third dimmer's wired but with nothing on the end yet.
Started with this:
Ended with this:
So. Into L2 of dimmer 1 is the supply (from a downrated 3A FSU off the ring main). There is a link wire from L2 of dimmer 1 to L2 of dimmer 2 and then to L2 of dimmer 3.
Into switched live of dimmer 1 are three live conductors for three supplies to five lamps.
Into switched live of dimmer 2 is one live conductor for a supply to three lamps, all daisy-chained.
Into switched live of dimmer 3 is a flex which is for a lamp which is not yet connected (end of flex is capped-off).
All the earths are terminated at the faceplate.
All neutrals are connected together on a Wago block; two conductors per port.
Dimmer 1 works fine to control the five lamps on that circuit.
Dimmer 2 switched the three lamps on and off fine but the dimmer control does nothing. The lamps remain ar what appears to be full output.
Dimmer 3 does nothing 'cos it's not connected to a lamp.
Now, I am not especially happy with the wiring because it looks to be too busy and there are probably too many conductors per dimmer or Wago port so I am open to suggestions for tidying that up. This is DIY work which will be tested by a qualified electrician and a Small Works certificate provided so I want the end result to be compliant.
But first I want to fix the problem with dimmer 2 not dimming. Have I made a wiring error?
Thanks for reading a long post and thanks for your advice.
