are they breakable in someway? there is lot of those at the Wasteland tower and i tried to drop them on eachother from the highest place and nothing. Only if they're dented. Solid, perfect-condition ones? No. thanks! This is actually incorrect. .
It is not required, but it can be a good idea. Personally, I would prefer them to be in conduit (e.g. ENT/smurf tube) with splices in junction boxes. Just like with electrical wires, it will protect them from damage while providing accessibility for splices.A junction box is not required for low voltage. However, using a junction box .
It is perfectly acceptable to fish a new cable unsupported and unsecured inside the wall cavity. The rules for low voltage are very relaxed. If this was a line voltage thermostat, .

If an exposed conductor of a low-voltage wire comes in contact with 120v, the higher voltage can damage what-ever is at the end of the low-voltage wire. solid connection between the exposed . A junction box is not required for low voltage. However, using a junction box may make the splice more reliable in the long term, by protecting it and securing the wires so it's . Typically, thermostats use small, low-voltage wires because they don’t need to carry a lot of power. They’ll usually be 18-22 gauge, though they can vary slightly with different .In the most basic system, this functionality is provided by use of a fan center relay, and the low voltage wiring to the thermostat now will require a minimum of three wires (for heat only units) and four wires (for heat / cool / fan) for control.
The low voltage thermostat wiring diagrams outlined in this article provide a comprehensive guide for understanding and implementing the wiring connections for various types of low voltage .

Typically, line voltage thermostats feature 2-4 thicker wires (single pole or double pole) which control the heat only. Four wire (double-pole) thermostats can be shut off whereas two-wire (single pole) thermostats can . They are claiming that as long as I junction the 18-2 into a 14-2 NM-B before it goes into my switch box then I don't have to separate the high and low voltage in the box. I .
Thus, the thermostat wires carry low-voltage power. This excludes thermostat wire splicing from certain safety regulations that are applicable for high-voltage conductors. It is for . In California I am installing a SPDT relay to activate a circulation pump from my thermostats. The relay takes a 24v trigger and connects the 120VAC for the pump. . The relay is designed to go into standard a knockout of a junction box and the wire leads are color coded for their function. But this means that I will have high voltage and low .
High and low voltage conductors in the same junction box must be separated by a barrier. Outdated NEC reference: 800-52(a)(1)c.1.Exception 1. In the typical dbl. gang box installation, power in one half and phone and data in the other, there needs to be a partition in the box separating the two classes of conductors.
I recently noticed that one of the zones stopped working because its thermostat wire in the basement was frayed. I removed that part of the wire an spliced in a new one. It is 18 gauge wire (2 wires) for a 24V relay. I cannot find any code that specifies: whether a junction box is needed. and if so, what type of junction box is requiredI guess theres no choice with that transformer. Even replacement boiler installs when converting from line to low volt controls, the thermostat wire is typically 14/2 romex. We always routed the 14/2 thermostat wires out of the junction 1900 box at the boiler. Low volt spliced outside the box. Line volt inside the box.
Are junction boxes required for thermostat wiring? . Can't be assed to look up the code right now, but no. Typically we'll throw a low voltage frame in just to have something stronger than drywall to attach to. Reply reply mdxchaos • .
Now that you have edited in a picture of the incredibly awful excuse for a junction, without a junction box, probably not using weatherproof wirenuts, outside, on your thermostat wiring - um, yeah. Even low voltage should be done "in a neat and professional manner" and whether or not you technically need a junction box for code, you surely need .You don't need a box for low voltage thermostat wires, abandoning wires like this is usually fine as long as its not hooked up to something on the other end. . They may be tapped off another circuit, or in the same junction box as another circuit. Personally, I'd stick each one in a bit of connector strip, or their own wago connector. That .Low voltage thermostat wires. Never needed a box before. Reply reply proton-23 • Low voltage wiring does not need a junction box for connections. You should always strain relieve the connections though. Doesn’t have to be fancy, just make sure the connection isn’t under any pulling forces. Reply reply .
At this voltage level, there will be no issue with signal interference with 120v AC. I am uncertain about NEC requirements on putting a low voltage (less than 50v) signal wire in a common conduit with AC building power. Normally, thermostat wires are not in conduit (no requirement). wiring methods for which they are designed and listed. Where the wiring method is conduit, tubing, Type AC cable, Type MC cable, Type MI cable, nonmetallic-sheathed cable, or other cables, a box or conduit body shall be installed at each conductor splice point, outlet point, switch point, junction

In others it seems to say that although low and high voltage wiring should not be in the same box, it is ok to do so. . (24V coil, 110V load), a 24V transformer, thermostat wires, and wires for boiler control and thermal detectors. I plan on labelling both the wires and the conduit locations. . The problem is more with the line voltage and . The non-hazardous low voltage terminals are to be on the outside of the box. Now, if your basement is unfinished, there's likely to be one of these junction boxes somewhere, with handy circuits behind it your electrician can tap. . The key to this type is you let the thermostat wire do the traveling, you fit the transformer in a less finished . This allows for the 120 volt or 277 volt wiring to be spliced inside the j-box, as would be expected. This also leaves the 24 volt low voltage wiring on the outside of the j-box. Typically we have spliced "in free air", above the t-bar ceiling (not used as a plenum) and run the wiring to the actual motion detector device. If the thermostat and the relay in the condensing unit are both OK to be driven from a Class 1 instead of Class 2 power source, then you can reclassify the thermostat circuit as Class 1, run it using ONLY Chapter 3 wiring methods (suitable for the power voltage) from end to end, and put that Chapter 3 wiring in the same conduit as the power wires.
I'm planning to wire electrical and networking cable in a new home, how far apart should the two types of wiring be from each other? I've heard many different rules of thumb, such as: the two types of wiring bundles should be anywhere form 12-24 inches away from each other, and also that if you need to cross a power line with a network line, do so at a perpendicular angle.Both a thermostat and a wired doorbell run on low voltage wiring from a transformer. The thermostat “should” be wired to your furnace transformer (I personally have a boiler that has the transformer bolted to it). This transformer .

What Does The Code Say About Installing Doorbell Transformer In Junction Box? The National Electric Code prohibits contractors from installing low-voltage wiring in a panel, conduit, or box that houses high-voltage circuits. Therefore, placing . at a job power went out in the living room so I thought maybe a breaker tripped. breaker was fine, I pulled all outlets in room out the wall, wiring was fine. I traced circuit to a junction box. Wires were burned and came apart. Why breaker didnt trip. and what causes a wire to melt that way.I want to run wires for LED strips under each stair. That means I plan to have a splice for each step. I got some wire nuts for this, but I also want to bury the wires in the wall. Of course, I would use a normal junction box if it was 120v, but it feels like overkill for 12v. On the other hand, I feel bad about just burying a junction. There's no NEC requirement that the end of an abandoned cable, energized or not, be inside a junction box. You can tape or wire nut it off and stuff it inside the wall, if you want to, and that's legal. One reason not to give DIY advice: Catch a man a fish and you can sell it to him.

When it comes to electrical installations, the choice between a metal or plastic junction box depends on the unique requirements of your project. Plastic boxes are cost-effective and lightweight. They are widely used for standard residential and low-voltage applications. Metal boxes are durable, fire-resistant, and good for grounding. They are used in demanding .That thermostat cable is not UV rated, should be ran in seal tight just like the high voltage, after a few years of exposure it’s likely it will start flaking and possibly cause a low voltage short. Edit: The brown coat might say it’s UV rated, but I’ve seen countless times where it gets hard and breaks apart when exposed to weather. HVAC thermostats are low-voltage thermostats that operate on 24 volts (a very low voltage), just enough to power the thermostat’s functions and controls - meaning there’s very little risk of electric shocks. However, a line voltage thermostat can use 120-240 volts.
Thanks for all of the replies. Dennis I have an Ideal 0 underground locator and will try it. Hillbilly this box was purposefully recessed and buried above the ceiling but I will still use my level to check for bevels. When installed on the wall, the Nest Thermostat should be 1.2-1.5 m above the floor. Connect the wires Connect the wires coming through the wall to Nest’s T1 and T2 terminals. It doesn’t matter which wire goes into which connector. Install the Nest Stand Attach the thermostat base to the stand according to the instructions that came with it.Should have a cover plate with a 1/2” hole that the 120v wires pass through into the box and free air the low voltage wires to the terminal screws on the low voltage side. You could also just buy a steel 2 gang blank finish cover and drill your own 1/2” hole. All that metal inside the box increases your odds of something shorting out also. The junction box is where the electrical wires come from. The junction box is where you will connect the wires to the cord set. How much does it cost to install a ceiling light fixture without existing? . Do low voltage wires need to be capped? The original answer was based on the voltage of the Maims. If it’s low voltage like a doorbell .
