Hi,
I am replacing a twin light switch with a twin dimmer, but I am puzzled by the way the switches were wired up.
Coming into the socket are two mains cables, labeled 1 and 2.
Both earths go to the earth in the housing.
Black 1 (live i gather) goes to the top of switch 1. Black 2 goes to the bottom of switch 2.
Red 1 goes to the bottom of switch 1, and then another red cable runs from that to the top of switch 2. The red from mains cable 2 is left hanging.
The dimer I have has 2 seperate units, with a live connector, a connector for the cable to the light, and an earth. I understand I just run a cable from the earth to the earth in the housing, but what do I do with the other cables? Why is that red cable left hanging in the air?
