Does anyone know what the voltage means on electrical wire sheathing? Some 14AWG wires show 600V and others are 800V.I have a burnt wire that shows 1000V.They are all 14AWG, stranded, copper wire. I just don't know what the voltage rating means. Does the wire support up to that many volts or does the sheath resist heat better the higher the number is?
The voltage shown is the maximum that the insulation can handle. Different types and thicknesses can handle different voltages before failing. Wires are burnt by current, not voltage.
