1. Introduction
The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of round wire, flat and sheet materials.

2.Marking
Each spool/package of alloy is supplied with a label or tag showing alloy type, nominal size, tare and net weight, resistance W/m (W/ft), charge number and a reference number.

3.size
wires:0.018-10mm                   Ribbons:0.05*0.2-2.0*6.0mm

Q: What is the difference between observing field wires, winter and summer? why? What should you watch if you set up a wire in the summer?: I am a water utility, I think less trunking, or do a good tube!

Q: I have taken out the rotating speaker from an old organ that I wish to externalize to another organ.It has its own transformer (I thinklittle metal-layered box with a wire core in the middle) labeled 115v 60hz. i cut the wires from it that went to the main power supply for the organ. What I am wondering is, can I just solder a plug onto the ends of the power wires and plug it in? Eventually I would install a switch of some sort. Anyhow, because it has the little 115V thingy, how can I plug this thing in?: Transformers can have extra Output terminals for different voltages. Re-wire yours as per the 1st set-up. You'll need a pwr. switch, altho it can be left energized, as in many devices' pwr. adaptors (which are just glorified transformers, eh? Your plan should work ok (house current is 110v, not 120 or 115, but hey). Hope somebody else can give you better specifics.

Q: The name of the plastic rope of the wire when the computer is installed: Sce did not understand your meaning, do not know what you want to ask.

Q: How much per square bus load, how many watts: . in fact, very simple, first in the top of the distribution box with a bridge section of the size of the square hole . the bridge will be extended to the distribution box above the square hole on the line . is not very simple, if still Did not learn, you can continue to ask me

Q: I installed a ceiling fan/light combo in my room. because of the location of the switches, the switch that controls the light is on one side of the room on circuit 1, and the switch that controls the fan is on the opposite side of the room on circuit 2. What is happening is that there is only 1 common (white) wire coming from the fan/light combo. My circuit breaker keeps tripping if the commons from circuit 1 and 2 are tied together on the one common from the fan/light. Is there a problem with my fan? Is there a problem with tying 2 commons together from 2 different circuits? Is it my fancy CB? (it's one of those new ones required in bedrooms can't remember the name right now). Thought about hooking up a normal CB tomorrow to see if that makes a difference. Any other suggestions?: If you trip the breaker, test to see if there is power in what you think is circuit 2. If you do indeed have power still in circuit 2 then you are on two different circuits(duh, I know) But I agree this sounds more like a three way circuit where your previous light was controlled from two different switches. I think it is unlikely that your fan has a problem. I think it is more likely that if you have two circuits, one of them is feeding current back into the neutral bus. Edit: OKso you have a 3 way circuit. Now the question is did the electrician who wired the unit do the 3-way partially in 14/2 which he would then use a white as a hot? This is very common though very much frowned upon. Keep a close eye on this and if you find there is funny things happening then check the commons as they enter the box and see if any is hot when you turn on a switch. Code states that circuit neutrals have to be isolated to the neutral bar. No combining circuits.

Q: i have a main service panel that was probably installed in the 70s or 80s. there is a bus bar on the right side that all of the white neutral wires terminate into. (there is also a bus bar on the left side, that is totally empty.) there are no bare copper ground wires visible anywhere in the box. the circuits all run from under the crawl space into exterior junction boxes on the siding, then up through metal conduit into the panel. i know some of the circuits are older, but some were added just in the last couple of years, and were done with permits. so how and where might the circuits be grounded?: It is possible the the copper wires were all stripped from the NM coating and attached to a copper rod or water pipe under the house, but it certainly isn't code to do that. Code requires the copper, white and black to all be attached to the appropriate bus in the circuit box, and then a bare copper wire running from the box to a copper rod driven six feet into the ground. The reason for the grounds to be in the box is because plumbing methods have improved and a simple plumbing repair with modern plastic pipe between the earth and the wires can result in no ground and someone touching a faucet getting electrocuted. Just so your home insurance will pay off in the event of a fire or an accident, you might want to check with the code dept. in your area and then have it changed to the box if required.

Q: Cable cable price (how much money a roll)? Own decoration with, and what brand of pipe how much money? More: See what you use the line of aluminum or copper wire tube with a good tube of gold

Q: I see military shoes, painted and then thrown on a telephone or electrical wire when people leave the Army, just wondering if other posts or military instalations around the US see this. I won't say were I am at, I don't want a MySpace thing happening to me, lets just say I am in the south. Does this happen anywhere elseanyone?: i've seen it at fort bliss alot

Q: I know that the color codes tell you whether its neutral and other purposes, but do i need to find the same colored wire to extend one, or do i need the same one? And are they just for safety purposes?: In the UK, it is a common misunderstanding that red is always live, and black or blue is neutral. While it is rare for a red wire to be used as a neutral, it is possible. And because twin and earth cables are so cheap, they are often used between ceiling roses and switches, so that the black or blue is live when the switch is in the ON position. It is good practice to mark this wire with a red sleeve to warn that it is NOT a neutral, but this doesn't always happen. It isn't a legal requirement for an extension to be the same colour but the wire should be the same current rating. In the UK, the modern system was designed to avoid cable joins in inaccessible places, like connection boxes between floor and ceiling, where a bad connection was more likely to start a fire.

Q: i dont know if this is to confusing to understand but i was jw if i could make heat using electricity and electrical wiring that can stay warm and can heat things up and that is rechargable that i can put in a coat or anything fabric or shirts or shoes can anyone help me out with this?: Current through a wire does cause heat. Look at the standard light bulb or electrical heaters. What you are proposing can be done but be sure you know what you're doing - we don't want you setting yourself ablaze.
