The cables i have are twin core just live and neutral and no earth.
I was planning to do the following:
wire the blue & brown from the bulb source to the 2 screws on the right (blue far right, brown next to this). from the plug lead, wire the brown to the screw on the far left (marked LSW) and the blue to share the screw with the other blue lead on the far right?
From my assumptions, what you appear to be saying is would result in a large "Bang" Could you be more specific please. The terminals have labels, please state which wire you intend to connect to which (labeled) terminal. A bigger picture of the wiring diagram would also help. Also what type and rating of lamp are you intending on using a not all lamps can be dimmed, and not all dimmers can dim all lamps
