Can you use a stranded wire for a thermostat?
You can use pretty much any wire you like for a thermostat as long as it is thick enough. Many newer thermostats will only accept at the thickest, 16 gauge so the ends may need to be trimmed to fit in the socket. Solid or stranded doesn't matter. Besides, what kind of wire do you use for a thermostat?
Can I splice a thermostat wire?
You can splice low voltage wires with solder and electrical tape or with various connectors or splicing kits. Shrink tubing gives a neater and more long-lasting result than electrical tape. Low voltage, underground wiring requires special treatment as does high current wiring. Secondly, can you run thermostat wire in conduit?
Can telephone wire be used for theromostat wire?
Phone wire would probably work fine in most millivolt situations, but some thermostat wire has decent current going through it (like 24V control loops), so - as always - why not use the right stuff. It might leak more current and not complete the circuit in long runs.the lighter wire, that is. Click to see full answer.
Is it OK to splice thermocouple wire?
When splicing thermocouples into an existing application, keep in mind that: Make sure that you are replacing one thermocouple with a similar Type (example: a Type K for Type K ). Make sure that the polarity is maintained (negative wire is red for ANSI/ASTM or White for IEC). Non-thermocouple splices are acceptable and will not result in an ...
Can you extend thermostat cable?
Yes, although the cross sectional area of the cable must not be less than the original sensor cable and not so long as to affect the NTC resistance. Sensor cables must be run away from mains cables to avoid interference.
Are thermostat wires live?
Wired thermostats are connected with fixed wiring from the heating circuit and typically the supply will be 3 core and earth cable. The live and neutral provide the power, and the switched live output allows the thermostat to switch the power on and off as it reads the ambient temperature.
Can you splice 2 wires together?
Simply strip the middle of your wire, remove the insulation using a hobby knife/soldering iron, wrap a separate wire/terminal to the exposed wire, and solder. When finished, add some heat shrink or hot glue for insulation. The image below shows a resistor and wire being added to the middle of two wires.
Can low voltage wire be spliced?
You can splice low voltage wires with solder and electrical tape or with various connectors or splicing kits. Choose your connecting method depending on the type of cable, the voltage and the current.
Can a thermostat wire shock you?
Virtually all room thermostats operate on low voltage that carries little risk of harmful electric shock. However, it is always wise to shut off power to a thermostat at the service panel before examining or working on it.
What happens if you wire a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Is it safe to splice electrical wire?
As the current travels through the splice, it can overheat and create a fire risk. When splicing wires, always use a junction box to place all the spliced wires. Junction boxes protect from electrocution and fires by containing any sparks that occur during a short circuit.

What is the best way to splice wires?
Using electrician's pliers, twist together the stripped ends of the corresponding wires from each strand of 12/2 Romex, white wire to white and black to black. Twist them until they are tightly joined, and secure each joint with a threaded wire cap/nut. Fold both sets of wires neatly into the junction box.

What is difference between Thhn and THWN?
THHN stands for Thermoplastic High Heat-resistant Nylon-coated. THWN wire is the same, but the "W" stands for water-resistant. The main difference between these two standards is their maximum temperature in wet locations.
Do thermostat wires have power?
While some people think the C wire is what powers the thermostat, this isn't entirely true. Typically, the "hot" wires, or the wires that provide power to the unit, are the heating and cooling wires, labeled Rc and Rh respectively. They provide the source of 24V power that comes into the main HVAC control board itself.
Can you install thermostat without turning off power?
The short answer is no, it's not OK - you increased your risk of electrocution and that's never a good thing specially for a DIYer.
Do I need to cut power to install thermostat?
The first step in how to install a thermostat is making sure the power is turned off to your existing thermostat. Turn off the power for your heating and air conditioning system at the main service panel. Its circuit breaker should be clearly labeled.
Can thermostat wires cause fire?
The safety commission reports that contact between the thermostat wires and household line voltage can damage the thermostat and cause a fire.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
Can you use a butt splice connector on thermostat?
A butt splice connector, or twist-on wire connector would be fine. Just make sure you use connectors that are designed for the size, and number of wires being connected. Technically, you should probably either pull all new wiring, so that it's continuous from HVAC to thermostat.
Where is Ideal connector made?
BETTER CHOICE for the DIY person is a new connector from Ideal which is approved by UL, made in USA, and available at Home Depot and Amazon ... Spliceline. More expensive than soldering and heatshrink, but easier and faster for sure; although a little bulkier.
Can you use a crimp connector on solid wire?
DO NOT use a crimp connector on solid conductors. NASA approves crimp connectors only on stranded wire, and specifically prohibits the use of crimp connectors on solid wire (see 4.3.4 on page 23 of the link below).
Can a furnace be shorted?
There is no issues with shorting. If the wires short your furnace will turn on. Thats all the thermostat does anyway.
Can you splice wires?
You can splice the wires. But if it's really no more work, I'd run a new intact one. Most electrical wiring failures occur at splices and terminations.
Can you use crimp connectors on a boat bilge?
If a dampish location like a dirt floor crawl space - I like to use the closed end crimp connectors (look similar to a wire nut, but crimp on). Twist wires together, crimp on the connector then fill the connector cavity / opening with GE Silicone II - corrosion ceases to be an issue even in a boat bilge. USCG approved for Inspected Small Passenger Vessels.
How much tension should be exerted on the splice to prove it was done right?
When complete, considerable tension should be exerted on the splice to prove it was done right. I would guess about 10 pounds would do the trick for t-stat wire. If nothing moves and a visible inspection shows no insulation was pushed into the metal portion of the crimp, then you are going to have one trusty reliable connection.
What class is thermostat wire?
I believe most thermostat wire is Class 2 and so article 725 prevails.
What to do if you don't have experience with crimps?
If you don't have experience with crimps, I would get a few and practice making them, then destroy them with tension, to get familiar with what you are working with.
Can you use splices in an unaccessible location?
I would avoid using splices in an unaccessible location if possible.

Can you bury a splice if it is not protected?
That said, burying any splice could be an issue if not protected so it doesn't separate! However, with low-voltage, that is a pretty rare!!
Do thermostats need to be in a box?
