They are breakers. So it seems OK. Thanks all for your help. Adam :D

Thank you both - very helpful. Dimmer fitted (including EARTH) and working. Is it normal for dimmer and fuse box to emit a quiet buzzing? Especially when lights dimmed? Adam :shock:

Is comm the terminal with the wiggly line and arrow through it? Thanks Adam :oops:

I am replacing a light switch with a dimmer. The existing switch has one black wire (top) and one red wire (bottom). The dimmer has three terminals: arrow, L2 and L1 - I am not sure which terminals to connect the wires to - or whether I have bought the right dimmer. Can anyone help? Adam :?
