aluminum wire expands and contracts with heat. copper is more stable. unfortunately you have aluminum. in a device connection, its not an issue. just make sure that your connection is secure, by pulling on the individual wires of the connection to be sure the wire doesn't pull apart. what you should check is the screws that hold your aluminum wire at the source, make sure those connections are tight. a loose connection will generate excessive heat.heat will melt metal, plastic, and cook body parts.make sure you are not grounded when you touch the source. I know of no electrician who would use aluminum wire in any application except a service entrance. I used copper on my own houses. Yes. You need special Al or AlCu devices for aluminum. Remeber aluminum reacts with copper so you can't connect aluminum to copper. Idontreallycare - Aluminum wiring was used in houses built in the 60s when there was a shortage of copper due to the Vietnam War. It is no longer used in new construction, but still exists in old houses

Is it legal to use aluminum wire for a stove or dryer in Florida?
aluminum wire violates code for any use anywhere in US. If this is true, why would aluminum wire be sold? I know it is used for service entrance.
What kind of circuit breaker should you use with aluminum wire?
Almost all circuit breakers are rated for copper (cu) or aluminum (al), there is a label on every breaker made, as long as it has the (al) marking it is suitable for use with aluminum wire
Can you use an aluminium wire instead of copper for a simple electrical circuit?
Yes, you can use an aluminum wire. Aluminum does conduct electricity. However, there is a well-known problem with aluminum wire. When exposed to air, the outer layer of aluminum forms a non-conductive oxide. There is resistance to the flow of electricity as it attempts to get through the aluminum oxide coating to the conductive aluminum below. When aluminum wire is used to reduce weight, it is usually welded to another metal that makes a better contact, such as copper. The contact metal is then what is connected.
What do you do when the ground wire from the wall is too short to reach the grounding screw on the new fixture plate?
Splice a new green wire to extend it, using the same size gauge of wire. Do not use wire nuts, use a proper electrical connector with grub-screws which can be securely tightened-up. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What to do with ground wire in wall when wiring metal light fixture without ground wire into plastic outlet box with ground wire Basically wall has 3 wires fixture has 2 and no place to ground to?
Don't worry about it some fixtures have no ground terminals. just shove the groung wire to the back of the box. Correction, if the fixture is metal and it shorts out, the metal surrounding the fixture could become electrified. That's why fixtures today are normally grounded to their mounting plates and then the lead is attached to the incoming romex. In the past, attaching these plates to metal boxes (either grounded by an incoming wire or grounded to the BX cable) eliminated the need for a ground wire. If the hot wire hit or shorted to the fixture, it would blow a fuse or circuit breaker. Many electrocutions and fires later, the folks at Underwriters realized that even that method of grounding wasn't sufficent (the old aluminum boxes and bx cables were crappy conductors. Solution; (and I practice what I preach because I remodel many old homes) get a little creative and spend the extra time to wrap a little ground wire to a mounting screw, or piece of metal, on the mounting plate of the fixture and then attach it to your incoming romex ground. On an old fixture, it could mean the difference between a fire and a tripped circuit breaker. If you have any metal boxes, old or new, ground to those too. <><><> Connect a pigtail to the metal canopy, and use a wire nut to connect the safety ground to it.

What metal are use to make electric wire and why?
copper plated aluminum wire
What size amp circuit breaker should be used in a kitchen with aluminum wire?
Don't use aluminum wire inside the house.
What type of conductors shall be used for wiring on fixture chains?
The type of wire you are looking for is called lamp cord. It comes in different colours usually to match the fixture. Fixtures hanging from chains use a clear insulation so as to blend in with the fixture chain colour. Remember that the smooth wire of the lamp cord connects to the hot wire and the ribbed wire on the lamp cord connects to the neutral wire in the ceiling junction box.

How do you ground a fixture if there is no ground wire from the wall and is it absolutely necessary to use the ground wire from the fixture or can you just cover it?
If you don't have the wire then you just can't ground it. This should not be too much of a problem. Most light fixtures are not grounded and some don't even have ground wires.

Is it illegal to use aluminun wire on power box?
No. Most large services use aluminum wire to keep the overall costs of the installation down.
Do you have to use a special fixture for mercury-vapor bulbs?
Yes, contained within the fixture body is a transformer that boosts the voltage to the required value that is needed to ignite the lamp starter.
