Wire Gauge Question

I have a covered (rafters, decking, shingles, etc) screen room out back. It used to have a single light, which I wanted to replace with a ceiling fan with light kit, independently switched. So I bought this fan/light dimmer: http://www.lowes.com/pd_69955-539-S2...d=10151&rpp=24



I checked the wire at the old light, and as it was 14-2, I removed it and replaced it with 14-3. It wasn't until after I spent 3 hours crawling around the attic on my stomach running the new line that it hit me....the circuit is on a 20 amp breaker. The line running to the switch, and a jumper running from it to 5 wall outlets in the living room, is all 12-2.



The new line runs straight from the switch to the fan box, with no other outlets. So while I doubt it is up to code, it seems like it should be ok. The fan/light won't pull anywhere near enough power to overheat the 14 gauge line, and if there is an actual fault, it should trip the 20 amp breaker anyway.



I would very much like to hear from the experts. Running the 14-3 was a serious pain in the butt, and replacing it with 12-3 would be just as bad. So if this is safe, I'd rather not replace it. But if I am risking a fire, it is obviously worth the hassle.

Hi,



I would like to wire a switch to be able to cut the power to the ceiling mounted outlets that feed our garage door openers. Running new wiring to them will be a bit cumbersome, so I am hoping to avoid that. The ceiling outlets are powered by light fixtures in the garage (one near by each outlet). There is a 3 wire romex cable running from the light switch to the first light and another one between the lights, and then regular 2 wire romex cables from the light fixtures to the outlets. The red wires in the 3 wire cables to the lights are switchable, the black wires are always hot.



I mainly want to be able to cut the power to the doors when we are away on vacation, and the reason for that is that one night both doors somehow opened up - I have no idea why. I'd hate for that to happen when we're away. Unplugging and plugging in the openers is a bit of a hassle due to the high ceiling.



I thought about wiring in a switched outlet so that I could just reach up with a long handle of some sort and switch off the power to the outlet. It would not be ideal, but definitely easier than getting the ladder out and unplugging the door openers.  However, there is possibly another option that I'd like some input on if anyone cares to comment. I believe I could wire in a switch on the wall next to the light switch that would allow me to cut the power to the black wires in the 3 wire cables. This would cut the power to the ceiling outlets and anything downstream from there (possibly an outside light, I would need to check on that).



My question is, are there any potential issues with this sort of wiring? Is there perhaps any code violation if both hot wires in a 3 wire cable can be switched off separately?



Thoughts?
      
I'm installing a new light in a closet with an in-line switch. Because of the build of my house, a mid-run receptacle is the only power source available without ripping open a bunch of wall and ceiling. I've got everything installed and tied into the receptacle with appropriate pig tails, but whenever I turn the power back on, the breaker for that circuit instantly flips. I've double-checked all the connections and wires, and they are connected to the appropriate terminals. Tied the pig tails into the terminals on the top socket of the receptacle.



Could this be the result of a faulty switch? The breaker trips whether the switch is in the off or on position, and there are no bulbs in the light fixture. I'm stumped. The receptacle in question is rarely used, and I've powered off everything else in the room to be on the safe side, but the breaker trips.
      
I am currently remodeling a bedroom in my home for a new baby.  I have gutted the room and am replacing all the electrical and adding new recessed lighting.  The room will also have a ceiling fan, along with the recessed lighting.  I am looking for a single gang light switch that will operate the ceiling fan independently of the recessed lighting, with a dimmer for the recessed lighting.  I don't have room for a double gang box where the switch is currently placed, as there is a closet in the way.  Is there such a thing as a switch that will operate the ceiling fan and it's lighting on a normal on/off switch, with a dimmer that can independently control the recessed lighting?  I have checked with the local big box stores and everyone has told me I will have to run two switches.  Is this the case?  Any info would be greatly appreciated.  Thanks in advance.
      
I only have one outlet in my living room and I need another one for sure. What are some ways I can do this?  There is not another outlet on the other side of the wall, we had a electrician come add a light with switch and he said something about closing off a line behind the switch box.  Is it possible to re-open that line? We also have a attic which I was told at homedepot is easy to do if you have another outlet in the next room you don't use. Any help is greatly appreciated!!
      
I have new 12/2 wire running to my attic (home built 1920) on a 20amp breaker.  My service is 100A and the box is older but not ancient.  The only thing on the line is a couple of outlets and 2 lights.  Would it be code to switch this breaker out for a tandem 15amp breaker?  This would open some space for me as my box is full.  Thanks.
      
I have 3 bedrooms on 15 amp circuits, 14 gauge wire. Original wiring is one bedroom is on one circuit and the other 2 bedrooms on another circuit. The wall switches in each switched the top half of an outlet in each room. I converted the wire at the wall switch to a 110V feed from the outlet and ran 14/3 from the switch to the ceiling for a ceiling fan. I replaced the outlets since the jumper was cut to isolate the 2 plug ins for switching. Is this whole scenario code compliant?
      
Hey guys and gals,



got a very odd dilemma, in my dining room there is a chandelier lamp that is controlled through a dimmer switch(even though it is not a dimmer). There is also a closet with a light switch as well.



The odd circumstance i am having is when the closet light is on(via its own switch), and you turn on the dinning room light, the closet light goes out. Then if you turn the dining room light off,the closet light turns back on.



The closest light switch has zero effect on the dining room light, the dining room light seems to have control over the closet light and dining room light.



Any ideas on a fix. I was thing just replacing the dimmer(once again does not actually dim) with a single pole interrupter. I just dont want to burn my house down
      
hello

I am dealing with what seems like a strange issue with a single pole switch, and I am royally baffled even after reaching out to someone a little more knowledgeable than me.



Yesterday: Replaced with a single pole switch with an identical one that I painted (for decor reasons). Two wires were going into the old, and the same 2 wires are attached to the new one. However, the light it controls fails to come on despite light bulb being good, and outlet located 4 feet below the switch fails to operate. With voltmeter in hand I tested voltages.

At the switch: 3 wires feed into it, all whites capped together, and 2 of the 3 blacks (A,B,C) are hot with 110. A is hot and was/is connected to one of the terminals of the single pole switch. B and C (hot) are capped together with a jumper that goes to the other terminal of the single pole switch. So I am royally baffled as to why a switch would be wired with 2 hot wires going into it. I swear it has been like that since we bought the house a year ago, and the light worked fine. I simply replaced the switch with the same wiring, and now it doesnt work. I even touched both hots (A and C) independently to wire B which (using common sense) should be the load wire to the lamp, but the lamp did not come one.



Other outlets in that circuit do not work either. They get 110 to line and ground, but not across the outlet.



I hope I was clear in explaining, and I hope someone can possibly shed some light so I can resolve this.



Thank you
      
I'm currently working on a house built in the 1930's. The electrical is a mess with a combination of a switch panel  and a fuse box with most of it still being knob and tube. I'm running a new electrical line to the air handler in the basement. This is due to it currently being tapped off a light circuit which also feeds an outlet in the kitchen, a bedroom, and half the outlets upstairs. (There's no rhyme or reason to the current electrical setup). 



  My main question is I'm running  12NM through bored holes in the studs to the air handler. Once I get to the handler and run it down to where it enters the appliance and switch box will I run in to codes problems. Should this run in the basement be inside a conduit or is NM cable okay? 

  Any guidance would be appreciated.
