Amp connectors used to join NM cables in manufactured homes ( to join sections together) are allowed to be installed in walls etc.
They need no junction boxes.
My question is if they need to be accessable, i.e. removable panel or crawl space or can they be plastered over ?
In a multi story modular building they are planning on putting them in the ceiling and plastering them over.
I think it is a bad design, finding one that fails becomes a major task, but may have to pass it because it isn't a Code violation.
