I work for a foreign chemical manufacturer as an operations consultant. I have no electircal background. But, as a chemical operator in the USA, I worked with the Killark hazard duty explosion proof recepticals, the kind with the "sleeve" that the plug is inserted into and turned 45 deg. to energize the plug. It is my understanding that the sleeve is for more than just keeping the receptical dry and dust free. Am I wrong? I was under the impression that it is also to support the plug with the cams on the plug secured into the sleeve. Also an old timer a long time ago said something about it being a flash suppressor in case of a spark.
The reason for my question is: The locals here use the Killark receptical and Appleton plugs resulting in a not to good of fit. They don't seem to be totally compatable with each other. So after struggling with the plugs the plant operators just take the sleeves off and plug in the power. Today I found a power plug body (casting) was cracked and the wiring was visible in the gap of the crack. Now I have to explain to these people why it is important not to tamper with the recepticles. The plug body appeared to have been bumped. It was not very stable in the recepticle so I think the sleeve is for support and protection as much as anything.
Can anybody on this planet answer this for me before these guys blow my old hide away?
Thanks,
