Here are three . Well, that depends on what kind of light switch it is as the process is different for both single pole and 3-way switches. For, single pole, you have to place the hot wire into the bottom of the switch box, while for the 3-way ones, . I have a Surefire light to go on a handgun. It is small, but very bright and takes a Cr123 3 volt battery. This thing gets very hot. I have a headlamp that goes on a hard hat for hunting at night, it uses a single 18650 .I'd go with a shallow box that would take an outlet and then wire that 12 volt system into a plug adapter. No reason other than that's what comes to mind. You could hardwire it into the box with the outlet. I'd think it would need a voltage .
Why is My Light Switch Hot? Top Reasons and Solutions
have (hot) 12/2 cable coming into a junction box, it leaves the box and goes to another outlet. In that same junction box I also have 2 12/2 light cables coming in - I guess the best way to make sure just those lights run on a switch is to run another black THHN wire from the junction box to the switch? no other more fancy/approved way ? This will include hot, switched hot, and neutral. - Pull an additional 12/2 or 14/2 cable alongside the existing cable. Cable A will carry always-hot and neutral for the switch and lamp. Cable B will carry switched-hot and neutral for the lamp. This means when the switch is on, neutral will make a seemingly redundant round-trip between the boxes.It is a 4-bulb fixture that is integrated into the ceiling fan. The (1) in master bedroom mystery switch is located in a two-gang box; the other switch in this box is a special, proprietary switch with 3 buttons. This special switch allows you to turn on/off the lights, dim the lights, and turn on/off the ceiling fan, all from this switch.
Replacing an old non-wifi dimmer switch. I forgot to take a picture of the wiring configuration, but if memory serves me, the red wire was capped to one of the black wires, the ground wires were twisted together and uncapped, and I can’t remember what was happening with the white wires. I was painting a joist in my basement and my roller bumped a junction box and sparks flew out. I suspect that a hot wire is touching the box. I was going to take apart the box and replace it with a plastic one that is bigger since a light fixture is there as well.
Keep in mind NEC 2014 has new rules broadly allowing grounds to be retrofit by running appropriate sized ground wires from any junction box to the panel, another junction box that has adequate size ground (or non-flex metal conduit back to the same panel, or the bare copper wires of the Grounding Electrode System (can't be cut, you use a split .This one is a single light switch to control one light in the room. The white wire seems to be the hot one. This one is a two-way light switch. The second switch controlling this switch is in the other room. The red and white seem to be running hot all the time while there are two wires (black and white) in the black connected with a wire nut.
That said, it looks like a standard 3-way setup. To make the receptacle always hot, remove the switches and connect the black wires together in each box. Cap the unused red wire at each end. I would cover the switch boxes with blank plates instead of patching it up; it's cheaper, less hassle, and much easier to access.
For the light switch side, the white/black is either the load (light) or the line (source). The red/white/black is running to the other three way switch on the other side of the room. The red and black are traveler wires, which is how a three way operates. Both .
Common Causes Of A Hot Light Switch. A hot light switch is a cause for concern as it indicates a problem that requires immediate attention from an electrical professional. There are several common causes that can result in a light switch becoming hot to the touch. Understanding these causes can help you identify the issue and seek appropriate electrical help.
Clarification: I think that there was a miscommunication in the post that you are referencing. It would be illegal for a neutral wire to be shut off (disengaging a light or device by breaking the neutral conductor). brhans didn't mean the fixture was hot (breaking neutral). brhans was saying the hot passes through the BOX and goes to the switch, and CarlWitthoft was . These are the lights with the small wiring box connected to the light itself, which snaps into a hole in the ceiling. The wiring box is very small, and contains hot and neutral pigtails with the fittings to insert supply wiring. My problem is that I want one of the lights on a three way switch circuit from the entry door to the exit door.At the light junction box there are so many hot/black wires (3 existing + 1 fan + 1 switch), and white (3 existing + fan) that its just a poor connection? Thanks!Edit: added pictures, not sure why they didnt attach first go around. There are three sets of inputs to the switched junction box. Switch junction box Once a wire gets hot, the heat can travel along the wire until it gets to an electrical connection, such as a plug in a wall socket. Once the connections in the plug get too hot, they melt and expose bare wires. These ultimately .

So if i run 14/3 downstairs from that box before going to the light from there.Is it okay for me to have both separate circuits in that one 2-gang box? The other option would be for me to abandon the upstairs circuit in that existing switch at the top of the stairs and just run the existing switch off the new circuit from downstairs. I switched of the main circuit breaker to the house and opened up a light switch to see if I had a neutral wire, so I could buy a smart switch. But when I took off the plate I found what appears to be a #14/2 wire hiding there in the back of the metal junction box-- just snipped off, with the hot, neutral, and ground wire exposed!
2-wire from the light to the first switch. 3-wire from that switch to the junction box and 3-wire to 2 other switches. Power comes in at Switch 3. Can I get power from this box or do I have to use a new line?
US code requires all light junction boxes to have a neutral, but does not require a live. Can all smart switches work without constant live (for example, in the case of a 3 way or 4 way switch) . but it would toggle between when is hot and which isn't as the switch gets toggled. Thank you! comments sorted by Best Top New Controversial Q&A Add . Ground and neutral are connected - test anywhere in the system with a multi-tester and you will get connectivity. Neutral is broken somewhere to this particular box. Since ground is connected to neutral, "fix" by connecting neutral and ground in this box. Which 100% works. But is 100% against code and can lead to dangerous situations.Trying to diagnose issue. Feed goes to center of junction box in the ceiling. Found my light switch wire and confirmed with black tape, however when I do this, black wire at the switch is also hot even when disconnected from the switch.
Why Is My Light Switch Hot? Possible Causes Explained
This is an updated version of the first arrangement. Because the electrical code as of the 2011 NEC update requires a neutral wire in most new switch boxes, a 3-wire cable runs between the light and SW1. The red and black are used for hot and the white neutral wire at the box allows for powering a timer, remote control, or other programmable device. I have a junction box in my house that (I thought) connect a hot line with a remote switch (near the junction box but on the other side of the wall) and a ceiling lighting fixture. The ceiling fixture is difficult to access. My goal was to add an .
Each switch is running 2 lights. 1 located in back of room one in front (so they can dim lights separately). I then ran a wire from each switch to a junction box in ceiling from hallway from here I ran a home run to main box and added a new 20 amp breaker. Circuit hot wire to 3-way light switch But in the ceiling box the incoming power (black or LINE) wire continues out to the first three-way switch. . For a light fixture such as a ceiling light, in addition to bringing power to the junction box where the light fixture is to be mounted (using 14-2 copper wire) we'd use a separate length of 14-2 .
