Electrical - How do wire this 2-gang dimmer switch? - Home - All sorted now, basically i have a plastic back field however the earths have a connector on them. The loop n terminals are for comfort, so i've simply offered a connector block to attach them up. The l1 and coms simply want to have the identical wiring on the new dimmer switch. I've not performed it yet however got my solution from every other discussion board. I am trying to match a dimmer switch in my dwelling room. I've two pendent lights managed by way of a unmarried wall socket with switches one for each light. My property is a brand new build and within the uk. The wires in l1 and com on the primary switch are striped in the direction of the cease of the cord, the stripped part is then in the l1 or com socket after which the cease of that cord is then type of bridged into the alternative l1 or com socket on the alternative switch. I tried this setup and it type of labored if lighting fixtures had been on and the lighting did dim (although flicked, perhaps wrong electricity bulbs) however when i attempted to show them off they blow experience the fuse inside the principal fuse box. Hassle is new dimmer switch does now not have a socket classified n loop. I tried replicating the wiring but wherein at the authentic sockets the wires are in the n (loop) ports, i have simply put them in l2 on the new socket as that changed into the simplest other port unused.
