Question about Lightolier Ivory Galaxy Slide Dimmer Switch 600w X600-i

1 Answer

So, with that being said, if we assume the white wire in the box is actually acting as a second black wire, when I went to hook up the first dimmer switch, I connected the black wire in the box to one of the black wires on the dimmer switch, then connected the white wire to the other black wire on the dimmer switch. The grounds went together. I flicked on the breaker, pressed the dimmer switch and the dimmer switch blew up. While I believe I had the wire nuts on securely, it is possible that when I was pushing the wires back in the box, one of them came loose and thats why the dimmer blew. I wanted to check on the wiring before I tried another dimmer switch and blew that one up too.

The most likely candidate is the white wire. In a standard residential installation, the white wire is often the neutral connection - and wiring the dimmer hot to neutral will cause exactly what you described.

However, often times the white wire is instead a traveller wire being run to the switch from the fixture (which, it sounds like that's what you were assuming) - in which case, the other likely candidate would be having a loose power connection coming in contact with ground. Sometimes this can be a loose screw or, as you describe, a loose wire.

Your best choice would be to install a standard 50-cent light switch first. If you connect it together and it works - then you know a connection came loose and made a bad contact - so then you can try using another dimmer. If you connect it and the breaker trips - then you know you're using the wrong wires/connections.

Can I reuse a Lutron Maestro MAW-603 dimmer in a 2 way situation?

you should be able to by hooking up the black wire on the dimmer to the hot wire(that comes from the electrical panel) in the wall box and the red wire from dimmer to the switch leg(the wire that goes to light fixture). if the dimmer has a white wire(nuetral wire) you will need to hook that up to the white wires in the wall box....CAUTION!!! when removing the old 1 pole switch, there should only be 2 wires and possibly a green or bare copper ground wire attached to it. if either of the 2 wires(not the ground) are white, IT IS MISLABLED OR MISCOLORED. DO NOT hook the dimmers white wire to it cuz it will fry the dimmer. If this is the case, then most likley you do not have a nuetral in the wall box but look anyway for a couple of white wires tied together with a wire nut and stuffed in the back of the box. if you find those than most likely thats your neutral(check with a wiggy or meter to be sure) and thats where the dimmers white wire goes. hook up the dimmers green wire to a green or bare copper wire in the wall box and then put a wire nut on the dimmers red w/white stripe wire.

Trying to install this thing, and having a slight issue. I've got a white, black and red line power line in the bathroom, obviously.. I've also got a dual switch Leviton 5634 which I'm just trying to...

I assume these three wires are coming to the switch box via from the light/fan unit and the light/fan unit has a box with 5 wires in it, including a white and black from the electric panel, and that the neutral is not routed to your switch box. I think your mistake is assuming that the black wire in the switch box is the hot wire, but it is actually the red or the white. Try switching the wires on your switch so that the red is common, If that doesn't work, try the white as common. Or you might open the box where the fan is, and confirm which of your three wires is connected to the hot black wire. Please vote if you found this helpful.
Good luck, Al K

I have a box with a red, white, and black 14 gauge wire coming in to it. Only the black is hot. I have a single pole dimmer switch with two blacks and a green (I assume a ground). When I wire the two...

I am assuming that this is original wiring in this box. As an electrician, I look at these wires in this manner. There are 3 wires, this is either a 3 way switch, a cable that is used with a light switch as well as passing power on to another box. This is how I see this problem with the information in the question. The black being hot, white as neutral, and the red as a return lead for a light. This is how I am looking at this as a switch feed. If you connect the black and red together, do you have the light come on? If so, then this is the correct two feeds for the light switch. The dimmer should be connected between these two wires. I am not sure if connecting between the black and white burnt out your dimmer, so I mention connecting the black and red to test for the light operation. You can also check in the light box itself, and determine which wires are connected to the light from the switch. I hope this helps. Joe

Need to hook this up to a lutron eco-t528-277-2 ballast which only has a hot,dimmed hot and neutral

If I understand correctly, you have Leviton florescent dimmer

And you want to connect dimmer to Lutron ECO-series ballast

This is the ballast with 3 wires: Hot dimmed, Neutral and Hot

Is this your dimmer???? Has Black, White, Red, Yellow-red, & Orange


Here's how to do it:
Dimmer yellow-red is not used except for 3-way switch >> cap it off with wire nut
Dimmer orange wire connects to ballast Dimmed Hot
Dimmer red wire connects to ballast Hot
Dimmer white wire connects to ballast Neutral

Those are your wires going to ballast. As you can see, you need 3 wires going to florescent fixture

Next, let's focus on Dimmer:
Dimmer green wire goes to bare ground wire
Dimmer black wire connects to Hot from breaker box (we'll test for that next)
Finally the Dimmer white wire connects to ballast Neutral as discussed above BUT is also has to connect to Neutral from breaker box

This means the Dimmer white wire is connected to 2 wires >> one wire goes to florescent fixture and the other wire comes from breaker box

So which wires come from breaker box??
It should be a black and white wire.
Let's test to find Hot and Neutral that come from breaker box.

Mark your wires.
Disconnect all the wires and separate from each other
Turn on power
Use ordinary tester
Tape tester leads to wood sticks so hands stay away from electricity
Power is on
Test each wire to bare copper wire
When tester lights up, that is Hot from breaker box ... this wire connects to Dimmer black wire
Now, test the hot wire to each of the other wires
When tester lights up, that is Neutral wire ... this wire connects to Dimmer white wire, and also connects to Ballast neutral.

Connect one wire at a time, and it will work.

How do you actually wire this? where do the wires go? I have 3 sets of wires coming to the power the second to another 3 way switch and the 3rd to the fan....all the whites go together (neutrals)...

Assuming the UK wiring code, all neutrals connect together, 2 reds connect to one side of the switch, and the black goes to the other side(this black should be "tagged" with a red marker to indicate the switched live)

Trying to hook up a dimmer switch it has a red black yellow and green wire the box has a black white and ground which wires get connected together?

For a single-pole installation:

1. Connect the 2 white wires together (one from the source and the other to/from the light fixture) - 2 wires
2. Connect the black wire from the source to the black wire on the dimmer switch - 2 wires
3. Connect the black wire to/from the light fixture to the red wire on the dimmer switch - 2 wires
4. Connect the ground wires - 3 wires
