DuPont Arc Flash Study

(OP)
thread238-386143: NFPA 70E Tables Maximum Clearing Time

WBD, there was an arc flash study you referenced saying that:

"Therefore using the tables is a compromise at best. There was a study done by DuPont on arc flash events at their facilities and they concluded:

having no PPE resulted in injuries 100% of the time
using the NFPA 70E tables resulted in less than adequate PPE resulting in injuries 50% of the time
performing a study to determine actual incident energy levels resulted in proper PPE and no injuries"

Where can I find that study? I'd like to reference it for training and to emphasize the need for an arc flash study.

Thanks,
Keith

Do a search on Ralph Lee and arc flash and you'll probably find some references. His work was in the early 1980's.
