What is a C wire?
A C-wire (Common wire) is the wire that is used to give a continuous supply of 24-volt power to a thermostat In simple terms. The ‘C’ means common. On most thermostat backplates it’s marked as ‘C.’. You should, however, note that it is not necessarily marked as ‘C.’.
What is the name of the wires that give the power supply?
Typically, the wires that give the power supply (usually termed as the ‘hot’ wires) are marked Rc (for cooling) and Rh (for heating). They give a 24-volt power supply from the HVAC system’s control panel. At times, they’re separate cables and need different attachments. Other times they may be the same cable.
What is an add a wire thermostat?
In circumstances where it’s too hard to install a new wire, the ‘Add-a-wire’ kit lets your thermostat use the current wires and still receive a constant supply of power without employing ‘power stealing.’
What to do if you see a port labeled C but it is empty?
If you happen to see a port labeled ‘C,’ but it is empty, check for any spare wires. At times, installers may run the common wire from the HVAC system’s control panel to the thermostat’s position, but fail to connect it.
What is the difference between current that is more than the threshold and current which is less than the threshold?
Current that is more than the threshold is ‘On,’ and current which is less than the threshold is ‘Off.’
Does a C wire provide power to a thermostat?
As you can see, the C-wire does not provide power to the thermostat. It gives a return path such that the thermostat is powered without disrupting the other cables. Which act as on/off switches for the appliances.
Do smart thermostats need a C wire?
Some thermostat manufacturers claim that their smart thermostats do not require a C-wire. This may not be the case for all. A C-wire is recommended to assist in improving the wireless network connectivity and prolong the battery life. Smart thermostats are meant to make life easier.
How many cuts to get through a single coil of wire?
Since it is not just a single strand of wire, it is difficult to cut and in the concertina configuration, you must make four cuts to get through a single coil of wire.
How many handles does concertina wire have?
At this point, you can start stringing out your lower two rolls of concertina wire. If you have standard military concertina, the coils will have two handles on each end. And if the rolls do not, you might want to fashion a couple handles out of baling wire for each end of the coils.
What happens to a tank when they try to breach concertina wire?
Tankers know what happens to a tank when they try to breach concertina wire. They know you can drive through single or even double strand if you are lucky, but that triple-strand barrier will mess up a tank’s suspension so badly, that it takes a crew hours to cut all of the wire out of the suspension and track by hand. I know this, because it happened to me when we sucked up a roll of single-strand concertina wire lining a road on an airfield. It took about three hours to cut it all out of the suspension. We were working with our sister platoon on another airfield in Iraq, and one of the tanks actually wound the wire between the road wheels and behind the wheels on the road wheel arms, pushing the center guide of the track out of its notch between the pairs of road wheels. When that tank commander rolled up to our tank line, you could hear the distinctive POP, POP, POP of a tank which is about to throw track. He had not wanted to open the tank skirts and cut it out in the field due to how vulnerable he and his crew would have been to potential sniper fire. Consequently though, he created a much nastier problem as described above. My soldiers and I had feelings ranging from disgust to a healthy respect of what concertina wire could do to a tank’s suspension, and I venture to say most tracked vehicle operators share those notions.
What wire do you need to tie a picket?
Along with your concertina wire, you will need barbed wire for triple the length of obstacle you wish to emplace and you will need a roll of baling wire to make your ties from the concertina wire to the pickets.
Can you break triple strand concertina wire?
The only way that the U.S. Army trains to breach triple-strand concertina wire obstacles is with explosives. You have to literally blow it up, because you cannot effectively cut a hole through the obstacle any other way. A quick word on why I would not recommend just single or double-strand concertina wire obstacles.
Can a tank punch through a concertina wire barrier?
And since a tank is the most deadly threat possible, anything less doesn’t stand a chance. You would think that a tank could punch right through a triple-strand concertina wire barrier, and it can.

Do you need leather gloves for stringing wire?
You need a pair of wire gloves for each person stringing wire. Heavy-duty leather gloves will work, but since concertina wire has little nasty razors on it, it can cut up a pair of leather gloves pretty badly if you are not very careful.
Types of Stranding
If a cable with a stranded conductor seems to be the appropriate choice for your application, you then need to consider the type of stranding. Although most constructions are specified by regulatory agencies, it is helpful to know some basic information about each type.
Custom Stranding
Additionally, you may require custom stranding such as a combination of the above like a Bunch Strand – Rope Lay, or Equilay, which offers Strands similar to those in concentric stranding, but lay length is the same for each layer. If you need a custom Stranding just let us know.
