Arc Flash Reduction Maintenance

[Pierre C Belarge]

Since Arc Flash seems to be at the forefront of so many conversations these days, I thought I would post this. I am not really sure how it would fit into the scheme of existing applications, but it is interesting to see how the manufacturers are spending big $$$ on the arc flash budgets.

It's worth noting on that last link that Schneider & Eaton worked together on that paper. Nice to see that they are willing to cooperate on safety like this. Very cool technology...

Excellent....I do alot of consulting for Eaton and they are always on the cutting edge. The idea will most certainly save lives and I also liked the fact they were the first to UP the standard AIC rating of their main breakers for residential panelboards to 35K versus 25K......

Luckily for folks like Eaton, with digital trip displays, they can set up multiple settings (alternate maintenance settings). As a side not, for manufacturers without digital trip displays on their big breakers, like Square D, they have zone interlock for the phase characteristics, to try and compete with arc flash reduction.
