MY IEC INSTRUCTOR ALSO HAD AN ENCOUNTER WITH AN I-LINE PNL(480-277V). HE SAID THE PANEL WAS OUTSIDE ABOUT 20'FT. FROM THE PAD MOUNTED XFMR, IT WAS MORNING WITH SOME DUE ON THE GROUND. HE HAD ALREADY TAKEN THE COVER OFF AND WAS ABOUT TO PUT A WRENCH TO THE FIRST BOLT HOLDING THE DEAD-FRONT, A FLASH OCCURED, GIVING HIM BURNS TO THE FACE AND HANDS. HIS WRATCHET-WRENCH WAS WELDED AT THE END FROM INNER ROTATING PART TO THE SOLID PART. HE HAD TO HAVE SKIN GRAFS ON ONE OF HIS HANDS, NOT TO MENTION LOOSING MOST OF HIS FACIAL HAIR.
THE EXPLENATION GIVEN TO HIM FOR THE FLASH WAS THAT THE AIR "IONIZED" CAUSING THE ACCIDENT.
JUST THOUGHT I'D RUN THIS BY YOU AND TO SEE WHO ALSO HAS A STORY ABOUT I-LINES.
