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.

Q:I am installing an electrical socket on the backside of a wall that already has an electrical socket. Does the electric wiring have a minimum length that I can cut it to or can I go as short as 3 feet?: No minimum. I just got done removing a bunch of electrical outlets that had been installed atop cubicle walls in back-to-back siamesed electrical boxes. There were wires coming off one outlet, through the back of the box, into another outlet. Total distance traveled, about three inches (through about 12 inches of wire). It passed inspection then, it would pass inspection now.

Q:A) Faulted electrical wiring can lead toB) Faulty electrical wiring can lead to: B is correct faulty is an adjective to describe a noun (electrical wiring) faulted is a verb.

Q:I had work in electrical business for about 10 years! I had my company overseas and I had a lot of projects done as well as building electric of a Mall! My question is what paperwork do I need, how long the procedure takes to obtain all the certificates and register company, how much would I need to invest and are there any big electric company that can offer me work and support as subcontractor in NJ or NY state!Thank you very much for your time!: Contact the website below to get an answer to what training and testing you will need for each category of electrician in New York.

Q:I have a ceiling fan with a light fixture attached and I accidentally cut the wires that go from the light fixture to the ceiling fan. Now the light is completely off but the fan is fine. However, there are wires hanging from the fan that spark when the fan comes on. Can I just buy some wire caps and be done with it?? Thank you!: call electrician before you burn down youre house

Q:can i use speaker wire to replace a section of wire that runs 2 12volt led lights in my car without it causing a fire?: Yes all your doing is getting power from one point to the next.

Q:HiI had a new electrical service put in, they connected the new wires to the old wire from the pole, My question is can you touch one wire at a time without getting zapped, (100 amp) the service wires coming from the poles to the meter.Because when they changed my service he striped the old wires and connected the new wires to the old wires.thank you: A qualified professional electrician can but for an untrained person it is very dangerous. Using the old power drops from the transformer to the weather head is the common practice and the power company is the one to make the change from the transformer to the weather head. Your electrician did the work as it should be done.

Q:I have a light switch that controls an outlet. Plugged into the outlet is a light for the room. I'm going to to install a wall light that will only work off the switch. So how do I make the switch only work the light and have the outlet work all the time? How can I wire this correctly?: source.

Q:I had a home inspection and the inspector pointed out a couple of instances where electrical wiring is in contact with some gas pipes and should be corrected. Why is this a problem?: Gas and electricity make a big boom when they mix. Wire and pipes move a little bit all the time this causes the pipe to wear through the insulation when that happens it go boom.

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:Describe how the electrical resistance of a wire changes as the wire becomes longer. How does the resistance change as the wires becomes thicker?: The resistance of a perfect resistor is R pAl where p is a resistivity constant (unchanged for a specific kind of wire), A is the cross sectional area (related to the thickness) and l is the length. If you increase l, can you see what happens to R?
