SOURCE: how do I install decora sureslide single pole dimmer switch??

Ok, first turn off power by finding the break box and switching to off. Then I'm assuming you mean by "socket" you mean the hole in electrical box mounted in or on your wall the dimmer is supposed to mount to. Sounds like your electrician ran the power back to the switch through your neutral/white wire. Your dimmer has a top and bottom, it also could possible have a tiny word imprinted that says "to light" and "+" if not attach the white from your socket to the top black wire on the dimmer, then connect bottom black wire to the socket's black wire...ground wires should connect to each other and to the ground in the wall socket. Use wire nuts to secure, then check to make sure no wires are touching anything except for what they are supposed to me touching...and test it before you permanently attach. Go switch power back on, and try your dimmer...if it works GREAT:) Now go turn off power one more time, tape your wire nuttted connections with electrical tape, mount dimmer and go turn back on the power. Hope this helped! Thanks

SOURCE: After instalation of 600w lutron

This, unfortuantely, is one of the usual challenges associated with dimming. The buzzing usually gets worse at around the 1/2 light level point. I don't think the issue has to do with whether the lamp is halogen, but rather how the lamp is physically constructed - and that differs from manufacturer to manufacturer. Long story short, I would take note of the lamps you purchased, and when replaced, I would opt for a different manufacturer.

Pair Siemens dimmer 300w sockets

You need THREE-WAY SWITCHES to be able to use them in tandem. SPDT (Single Pole Double Throw) switches.

You cannot install two ONE-WAY switches (SPST - Single Pole Single Throw) to switch from two loacations.

You CAN, however, use ONE Three-way dimmer on one end of the room, and one Three-way 'regular' switch on the other, if dimming from just one place is adequate for you

Which dimmer do you have. So I can look up the manual.
Are you using a fan dimmer, or light dimmer?
Does the dimmer feel warm to touch? or hot?
What does the dimmer control? Incandescent? Fluorescent?
How many total watts are being dimmed?
Is this a new dimmer or old dimmer that started having a problem?

I have a 600 watt 1 pole Diva dimmer controlling five 65BR30m for a total of 325 watts. With the slide control all the way to the top, the lights will not reach maximum brightness (as compared to...

First of all, in general, dimmers (even at their highest setting) cause the lights to dim even a little bit. If you are doing a 1-for-1 comparison, you may notice a difference - but honestly, it shouldn't be THAT dramatic that you're able to notice it.

My first suggestion is to double-check the model number. There's a version of Diva with a "G" in the model number (DV-603PG-) which was designed with a lower-high-end light level than normal (designed to guarantee extra energy-savings).

If the model number checks out, my next suggestion is to upgrade to a spec-grade product (like an NT-600-WH). The commercia/specification grade products have a higher high-end than the residential grade products. It still will dim the lights a little bit, but will be better.

After that, I suggest calling tech support at 1-800-523-9466 for more suggestions. Its a free call and they're available 24/7.

What Dimmer can I use That looks like an OS600 but is for a GU24 Dimmable CFL

Depending on your wiring, as to single pole (one switch location) or 3 way (two switch locations) you can use most dimmers. Leviton and Lutron have similar dimmers, and some specifically for cfl's.
Leviton has Sureslide, Illumitech, True Touch
Lutron has Diva, Skylark, and Lumea

Make sure your cfl is dimmable.

How to install a dimmer switch

This is a 3-way switch, made to control a light fixture that is also controlled by another switch in a different location. A typical example is a ceiling light fixture installed in an upstairs hallway, which could be controlled by switches at both top and bottom of the staircase.

The green wire in your switch is the ground connection, and joins to the green insulated or bare copper ground wire in the switch box. The red wire is the common connection. It connects either to the incoming AC hot wire from the electric panel, or to the hot terminal of the light fixture, depending on the switch location. The two black wires are traveller connections. They connect to the traveller terminals of the other 3-way switch.

If you purchased this switch as a replacement for a regular single-pole toggle switch or dimmer switch - one that controls a light from a single location only - then this isn't what you need and you can't use it. You'll know if you have a single-pole switch because it will have only three wires or screw connections. Return it and get a single-pole.

To install this as a replacement for a 3-way toggle switch or dimmer, connect the red wire to the wire going to the common terminal of the original switch. This will be a black- or brass-colored screw on a toggle switch, or the different-colored (not green, that's ground) wire on a dimmer. The black wires connect to the wires that go to the traveller screws (copper-colored) on a toggle switch, or the same-colored wires on a dimmer. It doesn't matter which traveller wire connects to which.

Note that if you're using a 3-way dimmer, only one of the switches can be a dimmer. The other switch has to be a plain old 3-way toggle.

No it means you have a short somewhere in the wireing. disconnect the power unhook the switches and use an ohm meter to test the wires to see if you have contact between the wires, black to white and black to bare ground wire. if it's a three way wire test all of them, if you used tsaoles to hold it in place check where you put the staples in you may find you have a staple ran threw two wires. Or if you pulled the wire and pulled it around a hard corner you may have pulled the insolation off somewhere the above test will confirm this. This is assumeming you are testing line voltage without a step down transformer or any other device in the circut

Lutron skylark s-10p 1000w dimmer. why is one

This video from the Lutron site shows the Diva switch but it is the video for the Skylark single pole switch also. It makes no mention of one wire being a larger gauge and does not differentiate which wire connects to line power and which to load. I do not think the wire gauge makes any difference.
