Wiring Up A Dimmer Switch Uk. I am trying to install a new ge 600w 120vac dimmer switch. If you have a metal face plate for your switch there should also be a green and yellow earth wire to a small terminal on this.
Turn off the power. Going into l1 of 2nd switch there was then a 4th piece of red wire not coming out of the wall going into the c of the 2nd switch. Use a common screwdriver.
Fold the wires neatly into the box.
Finish the job by installing the cover plate and turning on the power to test the new dimmer. You will find a red and black wire connected to the switch. I don t have any instruction for it. If you have a metal face plate for your switch there should also be a green and yellow earth wire to a small terminal on this.
