Fe-CuNi thermocouple (type J) is also named Fe- Constantan thermocouple. The positive leg Fe(JP) is made by pure Iron, and the main chemical composition of negative leg Constantan (JN) is Cu: Ni≈ 55%: 45%. Although they are all called Constantan, JN does not give the same EMF output curve as EN and TN, it cannot be instead by other Constantan.

The operating temperature range of type J thermocouple is -210~1200℃, but it is usually used in the temperature range 0~750℃ due to embrittlement of Iron.

Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with good temperature accuracy, sensitivity and stability. It is recommended for vacuum, oxidizing, reducing or inert atmospheres, but it can not be used in sulphurous atmosphere above 500℃.

Q:Can I run the single power from 3-wire 220 cord to both power receptacles in a hot tub panel made for 4-wire?: You should call a qualified professional electrician who has done hot tubs and spas. This is not a DIY project. There are several very fine points about a hot tub installation that if done wrong or not 100% correct can prove dangerous or fatal to any users of the hot tub. There is just too many chances for one little mistake to cause a very serious injury. it is not worth the risk.

Q:I have NO way to hook up electric to a whirlpool bath in 2nd floor (electric panel is in basement in opposite side of house) was planning to go out through attic then run line outside.to then come back into panel. What is the best way to protect wiring?. alsois it best to bury this line or make it so it can be clearly seen?: Joists are not wall studs. They bear weight and load differently. Drill a 1/2 to 3/4 inch hole through the joist at least 2inches up from the bottom, or dry wall side. Any lower and you can serious damage and weaken the joist in your ceiling. Good Luck

Q:i bought a duct fan that says to connect the wires (black, white, green) into the wires in the walls. can i wire the fan to an extension cord and then plug that into the wall instead of connecting to wires in the wall?: NO! Very unsafe. Sounds like you need an electrician.

Q:Will the cable voltage tolerance, such as 450V / 750V, whether it is 450V RMS, 750 peak? Thank you!: Simply can be tied with a rubber band on the line.

Q:I have a crap signal coming downstairs from my wireless modem upstairs. I was looking at buying a better wireless modem when the guy redirected me to this thing that you plug into your electrical outlet, and then there's a receiver to plug into an outlet near the second computer. He claims that it sends a far better signal than wireless because it sends the signal through your houses electrical wires.Anyone have any experience with it? Is it good? Also what's it called because I'm having a heck of a time looking it up online lmao.: Ethernet over power line adapters They are better than wireless, when they work. You have to use the outlets directly, you cannot use power bars or extension cords with them. Some have issues when on different sides of the power lines (each half of the 240V). Just try different outlets if having issues.

Q:I was in a room upstairs a few years ago (the one I'm in now) when i was about nine. I was hooking up N-64 or something and the wires started shaking. It wasn't a gentle shake though, it was a very violent shake. It seemed like there must have been someone back there shaking them, but of course there wasn't. Since then, I've been afraid of this room, especially at night when I have to turn the lights and computer off before I go to bed. I constantly feel like there's someone watching me. Does anyone have a reason why those wires were shaking that day? Do you think it could have been some type of paranormal activity, or just an electrical problem?: you may have experienced a seizure.

Q:I need to know if tackling a electrical light project by myself is doable, I have a fundamental understanding of electronics (no electrical background though): Well it really depends a lot on what power is available. If you have a plug below each area, run a wire up to a hole you cut out for a switch box, then run a wire from there to each of your lights. That's a basic set up. I hope that helps.

Q:Why is the wire hot when a short circuit occurs?: Who provided the more to the sub-gave to whom, thank you for helping

Q:ground electrical switch that doesnt have ground wire: Adding ground wire would be a simple fix. Chances are, if your switch does not have a ground, niether does your outlets and lighting fixtures. Simple fix, and safer.

Q:I want install 4 outlets 120/20A next each other in separate circuit breakers.The distance between panel and outlets around 150 feet. and run conduit 3/4. To save cost. How many or a minimum #12 wires can I use. I have 4 hot wires dedicated for each circuit breakers. And for neutral wires can i use 1or 2 white to all outlets and one green for all 4 outlets or I have to use sepreate neutral/w to each outlet from the panel.: With all due respect ,it sounds like you are not familiar with basic electrical wiring. You have left out many details in your question. What are the outlets being used for? Are they going to be used for outdoor use? Is the conduit going to be buried? If so ,it has to be buried to the right depth. You may not even need conduit if it is for receptacles indoors. Sometimes pvc needs expansion joints.There are more things to consider before doing this work. Two 110 volt circuits can share the same neutral as long as the 2 breakers are on different legs in your panel box. This is very important because if they are on the same leg you will overload the neutral wire.Sometimes it is better to put the two circuits on a 2 pole breaker so the circuits don't get separated. Many things to take into consideration. Once again, with all due respect,you should definitely get a licensed electrician involved in the project. If you are trying to save money, perhaps you can work out a deal with an electrician where you do alot of the work and the electrician comes in to make the hook ups and examines your work. Sometimes this does not work out if you do it wrong because then the electrician will have to change your work if it is not done properly and to code. Hope this helps. Good luck
