is romex wire copper or aluminum?

Despite the NM label, the individual electrical conductors within the cable are indeed metal—normally about 65-percent copper. NM cable comes in many wire gauges, but most household circuits will use 12-gauge or 14-gauge wire, with either two or three conductors inside (plus the bare copper ground wire).

i.e. Romex type wire stapled to studs and then traveling to light switch without benefit of conduit. I personally note in my reports exposed romex wiring in garage that is 7 ' or less and recommend that all electrical wiring is run inside of a conduit or behind wall to shield the wiring from accidental impact.

Characteristics: Copper is a reddish orange, soft metal that takes on a bright metallic luster. It is malleable, ductile, and an excellent conductor of heat and electricity – only silver has a higher electrical conductivity than copper. Copper surfaces exposed to air gradually tarnish to a dull, brownish color.

Knob and tube wiring is often #12 gage copper wire and can handle 20 amps. Note: Even though some knob and tube wiring is capable of handling 20 amps, we suggest that it be protected by 15 amp fuses because, in all likelihood, some modern #14 gage wire may be connected to the older #12 gage wiring.

Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity. These metals are both ductile and relatively resistant to corrosion, but they also have different properties which make them useful for various applications.

Electrical conductors are made up of metals such as, copper, aluminum, etc. These metals are used to make wires. Most wires are made out of copper because it conducts electricity with high flexibility and very little resistance. The first stage in the manufacturing process of a conductor is the wire-drawing.

To be classified as #1, the copper should be comprised of bus bars, clippings, commutator segments and wire of at least 1/16th of an inch in diameter. ... The most valuable type of copper pipe – clean copper tubing – may qualify as #1 copper as long as it is free of fittings, insulation, paint, solder and other materials.

Pigtailing aluminum wiring entails splicing a short length of copper wire to aluminum wire and then connect the copper wire to the electrical device approved for copper connection. The proper connectors must be used – approved for copper to aluminum connections – and antioxidant compounds.

Copper is the most commonly used material for making the connecting wire because of it's capacity as the good conductor of electricity and soldering property . Also it is the cheaper one.

Brass olives on copper, especially on hot water systems where their expansion properties are better than copper olives. Copper olives on plastic as per manfacturers regs. Copper on chrome pipe as they bite into the chrome better. I personally much prefer soldered fittings as they are much more secure.

RTD's require 3 wire configuration for better accuracy in measurements. So, any copper conductor( High Purity ) shall be used for this. Shielding of the cable is recommended for RFI/EMI immunity to the signals.

Watch out: tin-plated copper wire is a completely different product that, because its conductors sport a thin plated silver colored surface, might be mistaken for unsafe aluminum wire. It is not aluminum and it is safe unless, as with any electrical wiring, it has been damaged in some manner.

Copper wire is heavier, and aluminum is lighter and silver grey. The other main difference between copper and aluminum wires is the resistance of the material. ... Copper not only has a higher conductivity than aluminum, but is more ductile, with relatively high tensile strength, and can be soldered.
