The commissioning agent on a BSL3 lab we designed and which is under construction is recommending that we use "wet application" junction boxes for all wiring devices. Perhaps in place of all J-Boxes - I'm not clear on that yet. I confess to never having heard of these. He indicated that these were a best practice for the application. These have threaded conduit inputs so we'd have to convert to IMC and he mentioned something about caulking ahead of these boxes which I'm assuming implies a seal similar to explosion proof type. My confession here, is ignorance as to whether or not this really is a better way to go than ordinary J-Boxes. How critical is it (it would be a change order) and do we in fact need to apply a seal ahead of the J-box.
Thanks,
