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.
What gauge is phone wire?
Telephone wire comes in two gauges, 22 gauge and 24 gauge; 24 gauge is today’s standard. There are two types of common modular plugs; the RJ-11 and RJ-14. The most common is the RJ-11, which uses only two of the telephone wires in a four (or more) strand wire.
What type of wire is thermostat wire?
The most common thermostat cabling is 18/5 (18 gauge, 5 conductor), because 5 conductors typically offer enough functions for a modern thermostat/low voltage device.
Is thermostat wire the same as speaker wire?
It is rated CL2 (same as most in-wall speaker cables) which means it is adequate for class 2 circuits, which most speaker cables are. The only noticeable difference may be it is solid wire. Speaker cable is usually stranded. But it really makes no difference for in-wall wire.How many amps can thermostat wire handle?
The thermostat wire is sized for mechanical durability, not for current carrying capacity. Codes may require the circuit to be Class 2, 30 volts and 100 VA maximum, usually 24 volts and no more than 4 amps. It could be much less than 4 amps and most of the capacity may be required for the relays in the HVAC unit.
Can telephone wire handle 12 volts?
Telephone cable is designed for low voltage use, typically 48Vdc with 90Vac ringing signal. It is not rated for use as a power conductor either from a voltage or amperage standpoint. Normal power cable used in homes (in the USA) is rated 300 or 600 volts and is 14 or 12 gage AWG (15 or 20 Amp capacity.)
Is telephone wire 22 gauge?
Direct Burial Telephone Wire, 22 AWG, 2 Pair, Copper, Solid, Black.
Can regular wire be used as speaker wire?
The most basic answer is “yes, if you use regular electrical wire a speaker could work” — as long as you have two same-size conductors for positive and negative, you’ll get sound. There are differences in the metal used and in shielding (for some speaker wire, but not all).Can I use telephone wire for speakers?
Using existing telephone wire and powered speakers, it’s fairly simple to connect speakers throughout the house via existing phone lines. This will work only if the lines have 3 extra wires, such as when no land line is in use, or if the house has 6 (very common) or 8 strand telephone wire.
Can I use any wire for speaker wire?If you live in the USA or Europe, any old electrical wire will work. You can find electrical wire anywhere.
Article first time published onCan I use stranded wire for thermostat?
Nest thermostats don’t support stranded wires, they require solid-core copper wires.
How many wires does a thermostat wire have?
The most basic thermostat has 2 wires; usually a red and a white wire. Two wire thermostat wiring is used for furnaces only and usually doesn’t need a “C” or “Common” wire.
Can I use speaker wire for thermostat?
Aside from use as a power cord, you might consider running speaker wire through your walls in low-voltage applications, such as thermostats, sensors and hard-wired smart-home devices. … If you want to run the wire through a heat duct, you’ll need wire with the CL2P or CL3P rating.
How many watts can a thermostat handle?

How much power does a thermostat use?
Most thermostats that control central heating equipment, including furnaces, boilers, and heat pumps, are low-voltage thermostats that typically use 24 volts of electricity.
What is thermostat wire rated for?
A Class 2 power-limited cable for use in thermostat controls applications, bell and alarm systems, not to exceed 150 volts when installed as specified by the National Electrical Code® (NEC) and other applicable standards. Thermostat wire is sunlight resistant.
What are the 4 wires in a phone line?
In a typical home, the telephone cables connecting your phones within you home contain four wires… red, green, yellow and black. They are used in pairs for each phone line you have. Repairmen in fact refer to the wires in terms of “pairs”, so technically a standard four wire telephone line has two pairs.
Can CAT6 wire be used for telephone?
There would be no advantage to using CAT6 with a phone. … Distance CAT5e and CAT6 both have a maximum length of 328 feet. It is recommended to keep the runs to 295 or less when using patch cords.
Are phone lines AC or DC?
These two wires provide: DC current to power the telephone electronics, AC current to ring the telephone bell or electronic ringer, full duplex balanced voice path. This is a closed loop, balanced system not referenced to earth ground. The POTS phone line, with all phones on-hook, should measure around 48 volts DC.
How many amps does a telephone line use?
An off-hook telephone typically draws about 15 to 20 milliamps of DC current to operate, at a DC resistance around 180 ohms. The remaining voltage drop occurs over the copper wire path and over the telephone company circuits.
Does thicker speaker wire make a difference?
The thicker a wire or the lower the gauge, the less resistance. It is therefore a combination between speaker impedance, length and gauge that affects the resistance.
Does Ethernet carry audio?
In audio and broadcast engineering, Audio over Ethernet (sometimes AoE—not to be confused with ATA over Ethernet) is the use of an Ethernet-based network to distribute real-time digital audio.
What do you do with old phone lines in your house?
You can simply leave the phone jack in place and cover it up with a wall hanging, mirror, or work of art. This is the easiest way to deal with phone jacks that are high up on a wall, although it doesn’t make sense for phone jacks in other places. For those, you can move a stool or furniture in front of them.
Can you use Romex for speaker wire?
Romex makes for great speaker wire. The only problem is it’s too thick to terminate to connectors. It will snap off banana jacks when pushed into the box.
Can you get shocked by speaker wire?
Speaker wires cannot shock you. The amount of current that passes through speaker wires is very low and not strong enough to cause an electric shock to humans beings.
Can I mix 12 gauge and 14 gauge wire?
Originally Answered: Can I mix 12 and 14 gauge wire? The 12 gauge can carry more current, therefore; you must not use 14 gauge in place of 12 gauge, but you can use 12 gauge in place of 14 gauge, but 12 gauge is larger. Certainly, but you shouldn’t exceed the current capacity of the smaller conductor.
Can I use cat5 for thermostat wire?
Ethernet cable should work fine since thermostats use low voltage and low current. For simplicity, it’s probably easier to use each pair as if it were a single wire.
What is the difference between stranded wire and solid wire?
What are the main differences between solid and stranded conductors? Solid conductors are constructed of one, single piece of metal. … Stranded conductors are made of multiple small strands, which group together to make up a single conductor. It is more flexible than a solid conductor, but less durable.
Can I use Bell wire for thermostat?
Bell wire is not rated for outdoor use, but can be used inside a structure, or run inside outdoor conduit. … Thermostat wire, bell wire, or phone cable can be used for any 12-16-24 volt doorbell system, but can never be used for 120-240 volt applications, despite being rated for ≤150 volt.
What happens if you wire 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.
What is the blue wire on a thermostat?
The Blue or C Wire C wires or varying colors apply to every thermostat, but blue C wires belong to thermostats attached to a heat pump. Blue wires are for heat pumps. This wire connects to terminal B on your thermostat.
