Sure they do, in fact electrical faults can create some of the most intense blues/greens/purples and other spectrums of light you'll ever wanna see, especially if you see them up close and personal .... and God forbid you're in an enclosed space with it when it happens, intense it is.

Used to do hi voltage work, when testing last thing I would do is remove safety grounds. If any new guys or others inexperienced with electricity were near I'd ask them what color they thought electricity was. Then I'd have them observe closely as I pulled my ground (always remove it from the equipment end first) and slowly draw an arc out a couple inches from the lead, letting it arc and sizzle a moment so they could see the beautiful blueish/greenish/purpleish magic show. Static electricity, in many cases static would grow to thousands of volts in hi voltage subs.

Depending on how quickly the arcing extinguishes and what metals are involved you get some damn pretty blue/green/purples. So intense you cannot look, it is as lightning.

Some hilights of the link... 'Each and every day in North America, between five and 10 electrical explosions occur in commercial, industrial and institutional electrical equipment and machinery. '

Electric arc temperatures are considered to be approximately 4 times hotter than the sun’s surface. Temperature at arc terminals can reach 35,000°F (for reference, the surface temperature of the sun is ~9,000°F, and the temperature of a wood fire is ~900°F)

Heat radiation exposure is a function of:
Distance to arc
Available fault current
Fault clearing time
Equipment type
Gap between conductors (determined by equipment)
Vaporizes metals
Ignites clothing
200 degrees F - skin not curable (the point at which cell death occurs)
Possible to become fatally burned or seriously injured when working at a distance of 10 feet or more from an electrical explosion.

Electrical blast (or explosion) is the result of the rapid expansion of air caused by an electric arc.

Peaks in the first ½ cycle of fault (~ 9msec)
Pressure levels of 2,160 pounds per square foot (psf) in the immediate vicinity of the Electrical Explosion have been detected
Caused by superheating of air and vaporizing of conductors (air expands to roughly 1670 times and copper expands to roughly 67,000 times its volume – i.e. 1 in3 becomes 1.4 yd3)
Function of arc fault gap and available fault current

Made a lot of money over the years building and servicing such equipment, can confirm fault light-shows.

Really dumb fuck? What color does copper burn? Fucking pull your head out of your ass and think for yourself. Holly fuck

no he said protect not prevent

Wrong, how?
