Identifying A Circuit Type, With An Orange Wire

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!
      

wanted to get feeback on my crude wiring diagram i put together for my small bathroom remodel. does it appear to be sound or am i way off base??



details:



* 20A dedicated circuit

* 12/2 wiring

* outlet's will be GFCI

* double gang box will contain:

* timer unit for exhaust fan

* double switch for heat lamp and lights

* Ground wiring is not shown but each fixture/outlet/switch will be connected to ground wire

* by calculations, the 34cu box is fine for the number of conductors/size of wiring. per box specs could handle 15/12g wires.

* the scanner cut off the bottom part of the picture, the 2 lights on the right are fed from the same switch, neutral's connected together.



F = Exhaust Fan

L = Light

HL = Heat Lamp

T = Timer switch

S = Switch

H = Hot

N = Neutral

Wire Nuts are in the box connecting the pigtails



Thank you for your input.
      

Am doing a bathroom reno and installed a new fan. Original switch was a simple on off single pole. I want to install a DewPoint condensation fan switch that will turn on automatically at a certain moisture level.

The new switch as 4 wires. green ground, red fan, black power, and white neutral. I know the ground, but how do I hook up the neutral and fan to the existing fan set up?

There is a double pole light switch in the same box that has a couple wires to it, and there is a mass of whites that I am not sure where they go



Can I hook up the neutral somewhere else, or put it with the fan like a single pole? What do I do with this?



In the attached picture the switch on the right is the 2 pole light switch and on the left is the fan switch that I hope to replace.



Your Advice is appreciated
      

I installed an Intermatic brand programmable timer switch to operate some outside house lights (2 CFLs, total 30 watts). The thing worked for a few months and then became non-operational. I just realized that the sticker on the back of the timer switch states "max load ratings: 15 amp, 120 vac", and the circuit I installed it on is 20 amps. Is this why the switched failed? If so, why did it work for a few months? I thought 'load' was the amount of power needed to operate whatever is downstream of the switch, in this case my outside lights, which is under one amp?



Thanks!
      

I participate in a Pop-up camper discussion group (Popup Portal) and the following was posted reguarding the use of 30 amp extension cords:





"I just returned from Mobile Mart, my go to store for anything for my TT.  Was looking for a 25ft extension for my 30 amp power cord. The salesman  filled me in on some tips about buying extension cords for service.



1.  Never buy a black cord unless you have to have it now or it's the only  thing they have. The black cord absorbs and holds heat. We all know what  to much heat or amperage draw will do to an extension cord. Cords come  in a variety of colors.....orange, blue, yellow, etc. I picked up a  yellow one for visibility.



2. When your plugged in and have left  over cord DO NOT coil it up on the ground. Spread it out so any and all  heat can disipate easier. I usually pull just enough out to reach the  box and leave the rest inside the camper. I don't believe he was talking  about what is in the camper that but whatever is outside the camper  needs to be spread out.



3. If you have to have a lot of line  spread out to be able to plug in he suggested some type of covering to  shade the cord. I'm pretty sure this would pertain to monthly campers  and others that stay in one spot for awhile. Even still a good idea for  those of us that are down south here with temps in the triple digits."



I suggested that most (or all) of this is BS.



What say you?
      

I have a light switch in my kitchen that is not being used.  I plan to use it for a new light that will be installed over the counter.  The switch box has a 3 way wire that is live. I have a basic current tester that lights up "110 V" when it detects a live circuit.  When I use my circuit tester to test for current in the black wire (with neutral), it barely lights the tester.  When I test the red wire (with neutral), there is no current.  When i test the red and black together, the tester lights up nice and bright.  So I am a little confused.  I do not need it to be 3-way, this switch will only control one light.  Any advice on how to wire this?



Thanks!
      

Summary of what I'm doing:



Adding 2 outlets for above and below cabinet lighting.  Lights are line-level and plug into an outlet.  I want to install a single double-rocker switch to control each of these outlets.



All of the double rockers I can find are 15-amp.  The circuit I am planning to use for power is a 20a.  Am I sunk?  Will I need to install 2 single 20a switches?  I would only put 15a outlets in, obviously, but this doesn't seem like the right way.  Are there 20a switches that I just can't seem to find?



This is what I'm looking for:





One other thing, the circuit I am using for this is GFCI protected.  Should the lighting part of this circuit go to the load (to be GFCI protected) or is it advisable to put the lights before the GFCI?
      

This is kind of a complicated question, but I  think I have figured out how to do it right.  I wanted to run it by some folks here before going to the city code enforcer.  See the attached diagrams for details.



I  am planning a fairly elaborate lighting scheme for my home theater  area, mostly because I plan for the theater automation to be a hobby for  me. (I'm an electrical engineer)

 

I want to have banks of lights that I could later choose to group  differently onto dimmer switches.  For example, I have six can lights.   Some people I have talked to think I should dim the front four together  and back two separately.  Some think I should dim the front two together  and back four separately.  Some say I should dim them all together. 



So I decided I'd run each group of two cans to a junction box, run  the switches to a junction box, and then wire the switches to the lights  in the junction box - then I could later change it if I decided it should work  differently.  In addition, this would keep the junction boxes the  dimmers were in free from extra wires, since I plan to buy nice dimmers  that are fairly deep and would take more space in the switch boxes.  And  if I find that using switches differently would make it more intuitive,  I can change which switch controls which lights easily after the fact.   This would also allow me later to possibly control the lights with an  automated system.

 

There are some track lights and rope lights, as well as a couple  receptacles that would all come back to the junction box where they'd be  connected to the switches/dimmers.



I am bringing in power from  two circuits to balance the lighting.  I plan to put some of the lights  on one circuit and some on the other.  The second circuit has some other  stuff on it already, so it has less load left over, so most stuff will  go on the first circuit.

 

Also to save on wiring and make running wire easier, I was planning  to use 14/3 wiring where possible.  Any given 14/3 wire would  always be connected to only one of the circuits (no shared neutrals).



The attached files show my exact plan for each circuit. Note they both  share the junction box in the upper right corner of the pictures, they  also share the switch banks.  This allows me to decide which switches  control which lights, as well as decide which lights will be powered on  which circuit to balance them properly.  Note that the track lights are  each 2 circuit track, that's why I'm running 14/3 to each.

   

See the attached files for circuit #1 and circuit #2



I am running 14/3 NM to the switches.  I was planning to have two  switches share one 14/3 cable.  I am also running 14/3 to each group of  two light groups that I want to control separately.



I've also attached a diagram from the perspective of the junction box.



I also attached an example circuit on how I plan to use the 14/3 wire.

   

Here are some other decisions I made:



- The junction box will  be PVC 8x8x4 (256 cu. in.)  All the wires coming into the box add up to  70 cu in. so the box should be plenty large.

- All the grounds from both circuits will be tied together

  - The neutrals for both circuits will always be kept completely separate (NO shared neutrals)

- No 14/3 wire will ever carry power from more than one circuit (this would violate the shared neutrals anyway)



Even  though this is kind of elaborate and for hobby, I want to be sure to do  it safely and up to code.  Does anyone see anything wrong with  my plan?

 

Thanks,



Daniel
      

I was changing out old switches in an old apartment when I came across this enigma. Switches in the kitchen and hall both operate the hall light. The switch in the kitchen was a regular 3way switch job with a red, a black and a white wire. The switch in the hall had four wires, 2 black and 2 white. I replaced this with a 4way which my husband said was incorrect. In the mean time until we find the correct type of switch (which I'm open to suggestions) we put the old ones back on but must have messed something up because now the kitchen switch only works when the hall one is positioned "down".  I have multiple questions. What is the red wire hooked to? None of the wires in the 4-wire box read 110v so which one is the power coming in from? I'll stop here for now.  Thanks.
      

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.
