This is what I have. We have an overhead cable tray. The MCC panel is directly below it, in a seperate room. I have numerous pipes, ranging in size from 4" to 1-1/4" that will be stubbed, straight up no bends, through the ceiling to within 30" of the tray. These are GRC.
My question is does anybody know of a sealing fitting, that will screw onto the rigid, with an integral ground lug or grounding bushing. I've looked and can't find any. Suppliers don't have a clue what I'm talking about.
The reason it needs to be sealed is because, there is a floor above that is made of grating and I don't want something to fall into the pipes and into the MCC.
Rather not use ductseal.
Any help would be greatly appreciated. Sorry if in the wrong thread.
