Check for wiring properly. Check the instruction diagram. One of the three wires needs to stay capped.

Dimmer switch buzzing and lights won't stay lit

Check the rating of the dimmer switch. It is more than likely a 600-watt dimmer. Either way you should replace the dimmer switch with a 1000-watt rated dimmer switch.

I am replacing a Lightolier 3-way Dimmer switch with a Leviton IPI06-1LX Dimmer switch. When I install the dimmer switch it works fine. But the on/off regular wall switch won't turn the light on or...

It depends. Some dimmers are considered "smart dimmers," where the control on the other end of the 3-way has to be intelligent enough to send a signal back to the dimmer. If the Lightolier dimmer was a smart dimmer, then chances are that the 3-way control was designed to talk only to that specific dimmer. The Leviton product you replaced it with is a simple, basic dimmer - it should work in conjunction with a simple, basic 3-way switch.

If the 3-way control already IS a simple, basic 3-way switch - then I would simply re-check the wiring of the dimmer you replaced.

I need to hookup up a Grasslin GM40 timer controlling one load and a 120vac application. Just wondering if someone could verify the hookup terminals as I cannot read the schematic as it is mostly gone. ...

Open following links to identify timer and download manual:

GM40 can be used for 120V or 240V 277V applications for single-phase and some 3-phase applications.
For 120Volt, set all 4 dip switches to ON position BEFORE applying power.
ON position is pushed to left.

120Volt cable from breaker box has black hot and white neutral wire.
Black hot typically connects to terminal L1
White neutral connects to terminal L2/N
This action will power the time clock and relays.

Other terminals on GM40 are the relay terminals, and these terminals are dry.
Dry means they receive no power when wires are connected to L1 and L2/N.

There are two independent relays and each relay has 3 terminals: NC NO and COM.
If you are controlling one 120volt Load, then use one relay.
Run a jumper wire from terminal L1 to COM terminal.
So COM terminal is connected to Hot.

Cable going to 120V Load has black and white wire.
Connect black Load wire to terminal NO (normally open).
Connect white Load wire to L2/N.

I have 2 black wires at home one that usually connects to ON side of the switch and other black connects that OFF side (bottom) of the switch.. I'm trying to use Intermatics Touch CA3000 switch - but...

One of the blacks is a hot that connects to the black wire on the switch. The other black wire is the switch leg (to the light) that connects to the blue wire. The yellow wire on the switch is not connected in a single pole application. If you don't know which black wire is hot you'll need a volt tester.

The CA3000 is then controlled with the CA5500BR Handheld Remote with Smart Base.

I have two black wires in box attached to regular light switch & want to know if I can install a Skylark S-603PG single pole dimmer switch which has one black , one red&white, red and green wires

This is single-pole -or- 3-way dimmer
Manual shows on following link:

1) Manual says: The red/white wire is not used in a single-pole application. Twist a wire
nut over this wire for a single-pole application.
2) Green wire connects to bare ground wire. Or bare ground to bare ground.
3) Connect dimmer-red and dimmer-black to either insulated wire that came off of old switch

I am not quite the talking type but i don't wanna burn down the house

Need to know what is your issue. If you are asking how to hook it up it is a simple task. First you need to confirm if it is a single pole or 3-way switch. Does more than one switch control the light? If not is a single pole switch. I would first turn off the power to the switch you are replacing. Check this by turning on the light and turn off breakers one at a time until the light goes out. Take out old switch and connect new one. tkae one wire off old switch and connect it to one wire on dimmer. Doesn't matter which one. Take the second wire off the switch and connect it to the remaining wire of the dimmer. If you have a ground wire (bare copper wire) connected to the old switch and you have a bare or green wire on the dimmer, connect those together as well. Mount dimmer in box, re-energize circuit and you should be good to go. I am curious why you are using a 1000 watt switch (unless you are controlling more than 600 watts of lights)(9 65 watt bulbs = 585 watts). Let me know how you make out. Hope that helps.
