Replacing A 3way Electrical Switch.

I replaced a ceiling light with a fan/light with a remote. everthing works. their is one light switch and one dimmer switch. The dimmer switch has a red wire and a black wire connected to the black wires coming out of the dimmer switch, plus a green wire hooked to the metal portion of the dimmer. My question is: Do I have to remove the dimmer switch, if so, can I disconnect the red and black and hook them together? If I have to replace the dimmer with a regular switch, what kind of switch do I get?

Thank you
      

I am trying to install a SunSmart Digital Timer to my hall lightswitch (single pole). The timer has 5 wires: Black, White, Blue, Red, and Green. My switch box only has 3 wires: Black, White, and the bare ground wire. I connected the black to the black, white to white, and green to the bare ground. I have power to the timer but the light doesn't work. What should I do with the blue and red wires? Right now I have each capped off. Thanks.
      

I have two 3-way switches in my master bath that have never worked properly. The house is very old and has been worked on over the years by many different people with greatly varying levels of skill. I was finally fed up with these switches and tried to fix them. I tried to follow instructions I found online, so with the power off I disconnected all the wires from both switches, then turned the power back on and used my volt-meter to discover which wire was hot. It turned out to the a red wire at switch #1. The other two wires are white and black (and yes, there also is a ground). I connected this hot wire to the darkest screw, connected the white and black to the other two screws and tried to test for continuity at the other switch. I couldn't get a reading on any of the wires at the other end. I tried turning the power back on and testing to see which wire was now hot at the second switch. It was the white wire, so I attached that to the darkest terminal, and attached the red and black to the other two terminals. The switches don't work any better than they did before I started - that is, both switches have to be turned on for the light to come on. What is my problem here? Thank you!
      

Hi, I recently moved into a 1954 house with a  20amp electrical system, not the old fuse type, but there are no ground wires.



I removed an old light and replaced it with a light fan combo. As I removed the old light (after turning off the breaker) I noticed from the ceiling that there were 2 white wires tied together with a wire nut and 2 black wires, one attached to the white wire in the light and the other attached to the black one from the light. Feeling this was wrong and should be black to black, white to white, (even knowing full well the light was working fine before I disconnected it) I wired the fan the way I've always wired fan lights,  white to white, blue and black to black.  (again, knowing full well the light was working the other way). Turned breaker on then powered on switch. POP at the switch, breaker switched off. I reworked it back to the way it was before with whites tied off, black to white, black and blue to black, turned it back on and  viola, things worked fine. (I know, duh... Right???)

2 questions from this experience...

1. Why would the 2 whites be tied off with only black wires used?

And 2. It seems that one of the light switches in the same circuit as the blown one is now working soft. In other words, it used to make the normal click noise when turned on/off but now it just moves softly up and down without the click. Could I have damaged something when I mis-wired?
      

i have 3 switch sets in my house that are giving me absolute fits.



#1  kitchen switch, controls the light over the outside door




    Code:

   

3 sets of lines coming in,



line from the breaker panel (power)



line to the ceiling lights 



line to the outside porch light.

i cannot get this 3 line to work without tripping the breaker every time i turn the switch off



#2 bathroom switches




    Code:

   

power feed line



line to the light over the medicine cabinet



line to the second switch to control the exhaust fan.

same issue as the first set, flip the switch and trip the breaker (different breaker from the kitchen switch)



#3 living room switch and plug controlled via switch




    Code:

   

 power feed line



outside porch light line



line to wall switch to control the lower wall outlet

flip switch, trip breaker



the switches i have are "1 pole" am i using the wrong switches for this job?
      

I have an outdoor light fixture that I am trying to replace.  The house was built ten years ago.



When I removed the original lamp, I noticed one of the two leads was wired to the ground, and one was wired to the black wire, which is hot per my current sensor.  There are three wires in the box - black, ground (bare copper), and white or neutral, all from a single romex cable.  Unfortunately, I do not recall where the white was when I removed the original. 



I wired the new lamp per the instructions, something I have done many times before - black to black, white to white, and bare copper ground to ground.  Nothing.  The lamp and bulbs are brand new, and I have tried four separate bulbs.  I checked the black and neutral with my current sensor and with the switch on and the lamp installed this way, both show as hot. With the lamp not installed, the switch on, and the wires disconnected only the black shows as hot.  The switch is single pole, and appears to be wired correctly with a black to each screw on one side and a copper ground on the other.



Assuming the new fixture was bad, I reinstalled the old fixture correctly -  black to black, white to white, and bare copper ground to ground.  Still nothing. No light, and I confirmed the bulb is good by putting it in another lamp.   The only way to get it to light is to connect the neutral in the lamp to the bare copper ground.



I capped the wires, turned the circuit back on, and identified all the outlets, switches and fixtures on the same circuit.  I opened every one of them up (four lights and eight outlets) and found three (one switch and two fixtures in another room) where multiple commons connect.  All were properly connected.  My outlet tester shows all outlets as "correct".  I found no instances of grounds connected to commons or vice-versa.



Any ideas?  Is it proper to wire this thing the way I found it?



Thanks for any and all advice!
      

I am replacing the fan in one of our guest bedrooms and thought it would also be a good time to replace the switch.  Currently there is one switch to turn the fan and light on/off. 



I'd like to put the fan and light on two separate switches.  It appears that 12/3 or 14/3 is already in place (white, black and red/pink wires in switch enclosure w/ bare copper for ground).  I'd also like to make the light dimmable and the fan speed adjustable from these switches.  Could anyone recommend a good switch(es) to accomplish this?
      

Finishing basement and have a few questions...



1. Have already bought recessed cans. Commercial Electric brand. I have now read a few places that these are junk. Why exactly and should I return them? Need to know know before I paint them black.



2. I plan on installing 12 lights on new 15A circuit using 2 switches one for left side of basement one for right (6 x 6). This is OK yes? Both switches will be in same box. And will be only thing on this new circuit.



3. Assuming I am running hot lead from main panel to switch box...there is no fancy wiring that needs to be done correct? 14/2 black to black, white to white except at switch correct?
      

This should be simple but . . .



I am replacing a couple old 3 pole switches with 2 new decorator switches. First switch I rewired exactly like the old one black on black pole, a second black on brass pole on the same side, and red on the pole on the other side.



I rewired the second switch exactly like the old one was too.  White on black pole (I know ) red on the brass pole on the same side, and black on seperate pole on other side.



light will turn on and off from first switch but only off from second and will not turn on from first switch if second is turned off.



so I rewired second switch with balck on black pole, white on top brass pole, and red on seperate pole.  Nothing changed.



Do I need to test which wires are actually connecte to each other in the wall or what?



thanks for your electrical wisdom
      

Hello again Gurus,



Will a double pole 15A 277v light switch work as a shut off for my air handler? I had to run all the electrical prior to them installing the central air and I wired a double pole switch from my 15A double pole breaker. I ran to the line/load ie black/white to the bottom posts on the switch. Thinking they can just run black/white from the air handler to the top. When the switch is UP> Live power to air handler. If it it's down (OFF), it means they can service the unit. Is my thinking correct on this? I couldn't find any other switches.



Thank You
