junction box wiring check hot neutral The wiring sounds perfectly normal to me, for US standards: white wire = neutral. black wire = hot (unswitched) red wire = hot (switched) When the switch is on, the black and red wires are effectively connected together at the switch, so the voltage between them is zero. Metal roofing is typically made from recycled and recyclable materials. This makes metal roofing a sustainable option in addition to being extremely durable and long-lasting. You can feel good about choosing a metal roof, knowing you’ve made an environmentally-friendly choice that’s worth the cost.

The wiring sounds perfectly normal to me, for US standards: white wire = neutral. black wire = hot (unswitched) red wire = hot (switched) When the switch is on, the black and red wires are effectively connected together at the switch, so the voltage between them is zero. When testing a wire with a multimeter, it’s essential to know how to accurately measure voltage. This helps me identify hot wires and ensures safety during electrical work. I .To determine if you have a Neutral, you must first disable the live circuit from your electrical junction box to your switch. For the load you are verifying - start with the light on and switch .

I have a 4-switch junction box where three of the switches are on one circuit and the fourth switch is on its own circuit. I need to identify the neutral wire with the 4th switch to .
It had continuity between the photocell and that next junction box. I then went "upstream" on the conduit and opened another junction box, but it had quite a number of cable going into it. I preferred to not mess with them. So, instead, I found another nearby junction box that only had two romex cables going into it.Or check it out in the app stores TOPICS. . So I accidentally nicked the hot wire and neutral wire in my room while trying to install a receptacle directly above for my mounted TV in order to hide the power cable. . If you . "Modern home. Every box must have neutral" -- #1 not every box: some 3-way switch locations are exempt. #2 Even if neutral is present, if always-hot is not present it defeats the purpose of having neutral. Poaching neutral is Right Out. You cannot steal neutral from another cable (and certainly not another circuit).I connected the white wire on the 14/2 to the line terminal and the black wire on the 14/2 to the neutral, which powered on the dimmer switch with no issue. I also saw the switch listed in the WiFi networks available on my phone. I used a lever nut to connect the neutral from the switch, the red wire from the 14/3, and the black wire from the 14/2.
Clearly problem is in the junction box from hell. Crawl back to junction box from hell. Dad flips breakers one at a time until I find a wire nut that has wires from one side of the shared neutral and the completely separate circuit that's mistakenly tied to it. Separate into two respective groups and reconnect.
Installing new ceiling light - wondering which wire from the junction box is hot and which is neutral. Both wires are white. Both wires coming from the box are white and I stupidly didn’t take a picture when removing the previous light fixture. So I flipped the necessary breaker and opened the junction box. *** So - there were two 'hot' black wires - coming from opposite directions - wired together. In addition, there was one white 'hot' wire going back toward the breakers that was wired to 2 'neutral' white wires (not hot). Is that supposed to happen??? Stretch a ground wire across the floor to the work location (junction box for the light), either a plugged in 3 wire extension cord or a long single conductor wire connected to a known ground. Connect the grounded wire to the round ground prong of the tester.

This is most likely a multi wire branch circuit (very common). The neutral is shared in the 12/3. As long as the red and black are on opposite phases, the neutral will only carry the difference in current between the two hots. At this junction box the multi wire branch circuit splits into 2 .Connect the two black wires together using the UL Listed wire connectors. Connect the two red wires together using the UL Listed wire connectors. Connect the green or bare and white cooktop cable wires to the white (neutral) wire in the junction box using the UL Listed wire connectors. Install junction box cover.you can get a bigger junction box, or a duplex box with a combo cover plate that is blanked on 1 side/a receptacle cover on the other, or do one box just for junction with a blank cover and one for a receptacle. you can even add a cable going from the J box to the new receptacle box so that youd have one set going to the bottom contacts on the receptacle, and the other set going to ."To check if neutral and ground are switched, measure hot-neutral and hot-ground under load. . Overloaded neutral wire. Reversed polarity (hot and neutral wires are reversed). Missing ground wire. . If that's fine, it may be switched either in a junction box somewhere along the line, or back at the panel Reply reply
If I'm going to run THHN in conduit, can I use the same color for all conductors and ground, if I use different color electrical tape on the ends of the wire at each device/junction box to identify hot-1, hot-2, neutral, and ground? Asking because it's cheaper to buy one large roll of THHN than 4 smaller rolls (1 roll per color).
Posted by u/Yobacca42 - 4 votes and 7 commentsanother reason this happens is like in the situation someone wants some can lights in the ceiling but there's no way to get a wire up there so they will turn the ground into a neutral going to the original center light so that they can send a second hot up on the White and Branch off from the original light to get the can lights in.
Check it with a meter. Reply S_t_r_e_t_c_h_8_4 . Rather than running two romex lines, they just ran one, using live and neutral to run the hot wire down to the switch. Reply Resident-Bison-9340 . Too much in a junction box? r/electrical .Sometimes when ceiling boxes are roughed in, they use x/3 with ground cable so that they can supply 1 switched hot, 1 neural, 1 hot/switched hot, and 1 ground to the ceiling box. This allows a ceiling fan to be installed in such a way that the fan can be controlled either by a separate switch, or using only the attached pull chain.So that we're on the same page, in AC electrical wiring, there's hot/live (black, red, or blue), neutral/return (white), and ground (green or bare copper). You always need a neutral to complete an AC circuit. Connecting from one switch to another depends on the design. Most of the time is for convenience only. Check it under load and "hot to neutral" at breaker box. Check neutral connection in the main service box. It will be easy there, as you know which circuit it is. (by seeing which breaker interrupts power to switch) It's rare to be outside a box. mice etc. The connection will be discolored or even melting insulation when you find it.
There's probably only 12 feet of wiring, but I'd need about 50 feet of lead to reach both ends, since it goes between floors. As soon as the wiring leaves the junction box, the sniffer shows voltage on both sides of the Romex. But there in the box where the wire caps are, it only shows voltage on the hot wiring cap. I can see almost the whole run. In junction box splices, can I use black electrical tape for black wire (hot) and white electrical tape for the white neutral wire? Many people use black electrical tape or just 1 color of electrical tape in the splices in the junction boxes.
The power comes into the light box (with the neutral there too), and then this is essentially a LOOOONG loop with a switch at the end added in to the hot wire. You can either have the light always on and have power running to the outlet or leave it how it is. If there is a ground in the box, or if its a metal box and its grounded, then measuring from the hot wire would show voltage and the neutral would not. . and the positive probe to each of the wires in your light box. Only the hot should show voltage near line-level. (The neutral may show residual or induced voltage at a much lower level .What do you have on your 2 hots, do you have 120/240 or is just one leg live? It sounds like you have an open neutral somewhere. I'd start checking continuity moving back to the main panel.How to Wire a 3 Way Junction Box. A 3-way junction box is commonly used in electrical wiring to control a single light fixture from two separate switches. It allows for convenient operation of the light from multiple locations. Wiring a 3-way junction box involves connecting three separate wires: the hot wire, the traveler wire, and the neutral .
Posted by u/JBrutWhat - 1 vote and 12 comments Reversing Hot and Neutral Mistake: Reversing hot and neutral. This creates a shock hazard, and because the light or device will likely still work, you won’t even know it until it’s too late. Solution: Identify wires and terminals. In a standard NM-B cable, the black wire is the hot, the white is the neutral and the bare copper wire is the .
