The ground wire goes to the ground. The live goes to the black. In the electrical business red usually signifies a switched wire (or a second circuit). So therefore the red goes to the load (light fixture etc.).

SOURCE: On/off works but dimmers do not. leviton toggle

If each pendant has an individual transformer that is about the size of a hotwheel then you need a dimmer specifically for ELECTRONIC LOW VOLTAGE. A lot of electricians don't know that the different types of lights require different dimmers. Most store bought dimmers are for incandescent lights only, and some nicer dimmers like the Lutron Maestro's are rated for incandescent or MAGNETIC Low Voltage which require a different Sin wave interuption. I don't know that leviton makes a dimmer in that style for Electronic Low Voltage. You could install a Lutron DVELV300P-Wh, but that is a Decora opening.
Here is a link to explain the difference in how the dimmer needs to work. Good luck!

Testimonial: "Excellent answer! As Lutron is not available in my small town (on an island in Southeast Alaska) I will likely be ordering a dimmer online. Thanks!"

SOURCE: I am replacing a two

The best thing you can do in that situation is match the wire colors of the dimmer to the colors of the screw terminals on the switch you removed. Unfortunately, its too late for that - so here's my best guess: One of the black wires in the box will be coming from the same romex cable as the red wire. Take THAT black box wire and connect it to one of the red wires on the dimmer. Take the red box wire and connect it to the remaining red wire on the dimmer. Connect the black dimmer wire to the remaining black wire in the box. The two white connectors in the box get tied together - they don't get tied to the dimmer. And the ground (green) wire on the dimmer just connects to the bare ground connection in the box itself - or to the metal backbox - or cut it off and don't use it.

I have to replace trimatron push on/off Dimmer. the old that needs replacement has 2 "travelers" while the new one same manufacturere has back red and green. How do I connect to existing...

If the new one has black, red and green, then it must not be a 3-way. Green is universally the ground and the black and green would be the in and the out (either way) on a 2-way switch. You are one lead short! Good luck, Al K

Installed a dimmer switch to a light. Put power back on and the light came on. Wouldn't dim however and when I turned it off it would not come back on. fuse is OK

Is the dimmer rating higher than the load? Are you trying to dim fluorescent lamps? A flourescent requires special dimmer switch.

If you over loaded or mis-wired a transistor or wire wound dimmer, you may have damaged it.

Is this a three way light circuit?

The house has a red and black wire the trimatron has2 black one green am i missing a wire or does one black not get hooked up?

Rotary dimmers have 2 black wires, and the color-code tells electrician that both blacks are interchangeable.
This means that dimmer is for single pole only. That dimmer will not work for 3-way switching where more than 1 'switch' controls same Load (light fan motor)
Connect either black dimmer wire to the red, and connect other black dimmer wire to the black.
