Lessons Learned - 480 Volt Power Cable Connectors and Mating Tool; Emergency Cut Off Device for the 480 Volt Power Cables
Year: 1992
Abstract: Description of Driving Event:
During routine operation of the portable purge unit (PPU), the 480 volt power cable connectors exploded and melted, causing the unit to shut down. The explosion was caused when the connectors' overheated multi-point contact band caused the solder to melt, destroying the connectors' Integrity. It is confirmed that the force of the explosion could seriously injure or kill personnel within a 50' radius.
