What is Arc Flash?

[@lesleysmith6821]

Thank you I still don't fully get but it does make more sense. Basic rule of thumb don't go near electrical equipment if you don't know what you are doing ie me!

[@grendelum]

Lesley Smith - when I was an electronics repair apprentice (back when electronics were repaired and not just replaced) that was the first thing I was taught... _”...if you don’t know if it can hurt you or not, don’t touch it !!”_ Of course, I still got shocked a billion times from short circuits, but these were nothing relative to the dangers they’re talking about here !!

i am doing arc flash analysis on ETAP, May you guide me to do it in fair means?

[@bobcocampo]

Do you have cal/cm2 for Metal Sheet based on material and thickness?

[@roentgen226]

An arc inside a light bulb? Don't you mean a tungsten wire heating up to red hot?

[@Sparky-ww5re]

Maybe he means not your typical incandescent bulb, some bulb types , like metal halide, high pressure sodium used for street lighting, as well as the old school mercury vapor yard lamps now mostly replaced with LED, are classified as High Intensity Discharge lamps, and use an electric arc through a mixture of gasses and metals, same with fluorescent and neon lights used in decorative signs

[@roentgen226]

@@Sparky-ww5re yeah. Maybe

Hi Gale, thanks for reaching out. We have a chart, based on the Arc Flash Hazard PPE Categories under NFPA 70E - 2015 on our website, it can be viewed here: goo.gl/21cuaz

Gary Vale Nylon fabric is the worst. Arc flash coat is the best.

Most light bulbs are not arc lights.

[@uranium2327]

it's weird seeing corporate style nice graphics explaining one of the most horrifying ways to die. Arc flash = plasma grenade I dread to live long enough to see energy weapons be widely used

[@HoorGuvLabs]

no, arc flashes are only hotter than the surface of the sun. not the sun itself
