ETAP 6.0 ARC Flash

See if this helps http://www.klinglerelectricalsafety.com/images/articles/Arc-FlashProtection.pdf

I do not have much info about the whole idea of arc flash and PPE.

I will subscribe to this line of inquiry to learn as much as I can about this "new" hazard that I am exposed to almost daily!

With the machine that we used to build before the "economic turmoil" the higher voltage (480-600V) was separated from the control voltage. I would now consider the control voltage to be set at 24v dc just to minimize the problems with "ARC FLASH"

Sir,

The reply by Wareagle, with the reference should have helped you a lot. If I understand your data correctly, the software is stating that you have exceeded the 1.1 cal/cm² minimum energy level at a distance of 5.75 ft. This means that at any distance closer than 5.75 ft you must be wearing appropriate PPE of flame-retardant construction. Since energy is inversely proportional to the square of the distance, you can rather quickly approximate the energy at shorter distances. For example, at 3.0 ft it is (5.75/3.0)² x 1.1 ≈ 4.1 cal/cm² (approximately).

I am surprised that the documentation with the ETAP software did not provide this guidance.
