I had a quick look around and couldnt find a proper definition of what made a junction box 'maintenance free' and what I did find seemed to be almost implying that the manufacturers defined it as maintenance free rather than a specific standard.
I dont have access to all the relevant standards but I'm curious about what actually constitutes a maintenance free junction box?
