PTC thermistor alloy wires for Temperature Sensitive Resistance

PTC Alloy wire has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. It can automatically control temperature and adjust power by keeping constant current and limiting current.

Temp. Coeff. Of Resistance: TCR:0-100℃ ≥(3000-5000)X10^-6/℃

Resistivity: 0-100℃ 0.20-0.38μΩ.m

Q: I bought a mobile home and some of the wire's in the wall need to be replace but I don't know what gauge to buy.: 14 gauge wire 14-2

Q: For simplification, I am adding 3 20amp new outlets (OUTLET A, OUTLET B, OUTLET C)Anything below sound wrongAll Hot(Black wires) go on brass screws (Right Side of outlet)All Neutral(White wires) go on silver screws (Left Side of outlet)Romex Hot Neutral Path.Electric Panel to top screws on Outlet ABottom screws on Outlet A to top screws on Outlet BBottom screws on Outlet B to top screws on Outlet CBottom screws on Outlet C empty.Internal OutletsI am using blue pvc single gang boxes so for the ground add ground pigtails to the ground screw on the outlet and twist pigtail, incoming and outgling ground together with green twistcap.For Exterior Outlets I am using metal boxes. Should I pigtail the ground to the ground screw on the metal box or to the ground screw on the outlet?Any problems, suggestions, etc?thanks: It will work, but you are not really supposed to wire the receptacles that way. You are supposed to pigtail with wire nuts, but everybody does it your way.

Q: Why the birds standing on the wire ah what the line will not be electric shock?: The specific need to see how many of your home wiring drawings. But with the line to pay attention to, lighting needs more than 1.5 copper wire, socket 2.5 or more, air conditioning need at least 4 square above the line. 1.5 square feet of 50m, 2.5 square meters of 100 meters, 4 square meters of 50 meters. The specific depends on the line layout, it is best to let the electrician to see you, the material can buy their own. Let the electrician look at the actual needs. Water pipes, 40 to 50 meters is enough, pipe fittings need to calculate the appropriate parts, it is recommended to see the water utility.

Q: I saw a show about how it can affect the way you feel temperature, and light touches. There were a few cases in which the electrical wiring needed to be fixed, and that ultimately resolved the situation of the supposed paranormal. Anybody experienced this?: I have heard that when it rains or an electrical storm is in progress, that paranormal activity can happen easier. Bad wiring can play a big role in playing tricks on peoples heads, and funny scary feelings, it's to do with the EMF output it gives off. ~

Q: I have two outlets, and overhead light with a wall switch that are not functioning. The outlets when tested indicate a hot / grd reversed. The bulbs are new. The switch measures 120V at both leads when measured from the ground screw on the switch. 120V is seen at both wires if the switch is either on or off. No other outlets in the room are showing any problems.Also note this is not new wiring and everything was working fine until yesterday.What should I be looking for? What could be causing this problem?: What was done yesterday? That is where you start looking for the problem. The switch tells us one circuit is in the wrong place. Somewhere the light switch has 2 hot legs to it. The hot and neutral reversed in an outlet could be feeding the power to the switch through the light. This also could be caused by an open neutral someplace in the wiring. The most likely problem with all of these problems is not going to be easy to find without an on site inspection. Call a qualified professional electrician to do the work. When testing the system be certain everything is unplugged and you use an analog or solenoid type voltage tester on the switch. A digital meter will give a false voltage reading for power present in many instances.

Q: How can I run electrical wire 2700 ft without signifigant voltage drop only 110 volts: Use the largest gauge wire you can afford.

Q: I am replacing an existing electrical short wire (about 3 inches - can't tell what it is) from my circuit panel to my central air breaker box. I am also extending it 15 feet. My air conditioner panel box is rated for 30 amps, but my air conditioner has a max value of 22.6 Amps imprinted on the side. I bought some 12-2 wire, but should I go with the 10 gage instead?: You need to use # 10 AWG wire because the breaker is rated at 30 amps. Note that # 12 AWG is ok for up to 20 amps.

Q: That is now the new house has that position in the living room sofa wall mosaic of a small iron box, about 40 × 25 cm, which there are many wires called the box? Know friends say ~ thank you! More: The general aluminum processing enterprises can produce, Note: the use of extrusion production enterprises

Q: --A wire of resistance 10 ohms is bent to form a circle. Calculate the resistance between two points at the end of the diameter.--I can't understand this. Please show me the steps for finding the answer. I will appreciate your help.: I'm okorder

Q: I want to have my house re-wired, how much is involved? How much does it typically cost?Some more info: my house was built in the 1950's. I know the fuse box was updated, but my boyfriend and I are renovating it. Some outlets don't work and that scares me a lot. I'm on a budget, so please let me know what you think it will cost, as well as whats involved.Thanks in adavance:): It's a Big job. Get several estimates from electricians. Replace ALL wire, outlets (and add more), switches, etc. This may require holes in walls, etc but it will be worth it in the long run for convenience, safety, and resale value.
