The lay-in lugs are not listed for use outdoors and will weld up with rust in little time.
Best bet is to replace the lug only with one of the several available that are listed for direct burial and have been used to bond modules in years past. It is a compromise as the bushing itself is not listed for use outdoors either, but I think it is the lay-in lug that is the big problem. I believe this has been discussed here in the past. BTW, it is not being used as a strain relief, just a conduit end protector (there is no gripping of conductors) and a conduit bonding point. -Glenn From: RE-wrenches [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of AE Solar Sent: Tuesday, February 16, 2016 5:51 PM To: RE-wrenches Subject: [RE-wrenches] MIGB's Wrenchers, What are you all using as strain reliefs on the ends of conduit runs that run between arrays on roof mounts? We have arrays on two roof sections with a piece of rigid conduit connecting the two, and galvanized MIGB's (ground bushings maybe some people call them?) on each end of the pipe. It was just cited on an inspection that this was improper use of equipment because the galv MIGB's are not rated for outdoor use? Anyone have anything to back up the use of this method or have a preferred method for strain relief and bonding for this application? Thanks for any thoughts.
