- bare copper wire is copper orange color.
- tinned copper wire is silvery color.
- enamel coated copper magnet wire can come in any color, depending on enamel.
- plastic coated copper hookup wire can come in any color, depending on plastic.
copper wire for household wiring is color coded using plastic coating:
- black - hot 120 VAC
- white - neutral 0 V current return
- green - ground 0 V safety return (no current normally)
- red - hot 120 VAC, opposite phase from black for use in 240 VAC hookups
- etc.
copper wiring for industrial 3-phase power has additional colors, which I won't visit here.
copper wire for electronic use follows an entirely different color code:
- red - positive DC power
- black - DC return
- green - negative DC power, or signal if no negative power
- other colors - signals
don't confuse color codes!

What size cold water ground for a 200 amp residential service?
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
What is a Grounded conductor?
The grounded conductor (Neutral) can be white or gray. The grounding conductor can be solid green, Green with a yellow tracer or bare copper.
What is the electrical resistance of 18 awg copper wire?
18 AWG copper wire is equivalent to 0.75mm2 nominal. The resistance of a particular copper wire depends on a number of factors like ambient temperature, the type and number of strands of conductor, when plated, the type of plating metal (e.g. tin, silver), etc.A good value to use for solid #18 AWG copper is 21.8 ohms/km.Please see the useful Related Link link below.
What is the advantage of stranded wires?
Flexibility is the main advantage of stranded wires; however for high frequency AC (i.e. radio frequencies), stranded wires increase the surface area, minimizing the skin effect (i.e. high frequency current avoiding the core of a wire, increasing its resistance at that frequency). This is not an issue at typical power frequencies (e.g. 60Hz) as the skin effect is still insignificant at those frequencies.
Composition of copper wire in generators?
how much copper is in copper wire
What is the colour of CuI copper iodide?
Is it a white solid? I'm not sure.
What distinguishes a compound like copper sulfate from an ordinary mixture of copper powder sulfur?
There are two copper oxides. Copper I oxide (Cu2O) and copper II oxide (CuO) both contain copper and oxygen. Copper II oxide is a reddish solid and Copper II oxide is a black solid. Both are insoluble in water. Copper sulfate (CuSO4) contains copper, sulfur, and oxygen. It is most often found in its hydrated form as a blue solid, but allso occurs in its anhydrous form as a white solid. It is soluble in water.
What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
Copper is which type of solid?
Copper is a metal & solid
Solid copper reacts with solid sulfur to form solid copper I sulfide?
Solid copper reacts with solid sulfur to form Copper(I) sulfide. 2Cu(s)+S(s) -> Cu2S(s)
Is Copper II hydroxide a solid liquid or gas?
Copper Sulphate is a blue crystalline solid.
What is solid copper sulfate?
Copper sulfate in the solid form are crystals
What is the state of matter of Copper 2 Sulfate at room temperature?
Copper Sulphate is a powder at room temperature, therefore it is a solid.
Is copper carbonate a solid liguid or gas?
copper (II) carbonate is a solid
Is copper oxide a solid?
Yes, copper(II) oxide is a solid at standard and room temperature. Copper(I) oxide is also a solid in these conditions as well.
Is copper a gas?
No, copper is a solid metal.
Solid copper reacts with solid sulfur to form solid copper you sulfide?
