ok I am not as clever as I thought i was, I am trying to fit down lights in the bedroom, have got them in and connected but they dont work correctly.
I have connected into the p live with a junction box and fed back to a double dimmer however while the switch works ok i cant turn on the downlights on there own, they will only work when the main light side of the dimmer is on, the down light side will dim the spots but the main light (existing) dims both, not sure if it is wireing or maybe the dimmer switch will not work two seperate circuits help!!!!!!!!!!!
