3 Way Switch/Dimmer Installation Help

zachp04 said:

Hey There,

I am trying to install a new wall dimmer to replace my old one. (I needed something LED compatible.) [Pictures at link below for reference to following description] On the old dimmer, there were 2 wires coming off it. One wire joined to 3 wires coming out of the wall. (2 black, 1 red). The second wire coming off the old one joined with 1 black wire. There did not appear to be a ground.

On the new dimmer, there are 4 wires. See attached photo album below for a reference. With the exception of the ground wire, I am not sure where these fit in with the old wires. Any help would be appreciated, and please ask for any additional info.

Black should be hot/common and the reds travelers.

Tell in the US if it required a neutral it would have a white wire

Zach do you have the paper work that come with the switch. If so take a picture of the wiring diagram

Westward he didn’t say that it was a 3 way switch but I use red as travelers when I do wire a 3 way but in this particular case no.

His existing switches are not three way but the dimmer switch has the capability of being so, it is however suitable for use at his existing arrangement providing the unused traveler is made safe.

What would be required in order for it to be "made safe"?
