Podcast #10 : Arc Flash Safety

Identifying Design Solutions for Optimum Arc Flash Safety

Podcasts are Q&A with Schneider Electric engineers and experts.

In This podcast are questions asked during the “Identifying Design Solutions for Optimum Arc Flash Safety” webinar hosted by Schneider Electric.

Questions answered in this Podcast are:

1. How does one determine incident energy without all short circuit information?
2. What are the differences in arc flash studies with the door open versus doors closed?
3. What about small 240 volt systems? Does the 125 kVA transformer size apply to them, or just to 208 volt systems?
4. What is your recommendation for maintaining batteries in a UPS with a DC incident energy level well above 100 cal/cm2, when batteries by nature can’t be shut down?
