I may be hijacking...
I am installing pvc conduit in block walls. All voids are filled with grout. I have receptacles, lighting and fire alarm outlets and pvc links to deep 4x4 boxes with extension ring above the grid ceiling at different elevations- the extension ring limit is not a factor here. Later on, extension rings will be installed to run surface conduit to load centers or another box above the grid ceiling but further away.
I have to hear it from the brick layers who don't want to cut block to accomodate my boxes above, they argue a simple pvc elbow high up should suffice. I have seen this before, where you have the elbow stick out, then you install a 4x4 box over it thru a back KO, elbow is cut a bit into the box so to not abrade the wire around the KO during wire pulls.
I mean I could do that or add a male connector but now my box sticks out and I have to engineer a way to support it. I can also chip around the block and deep set my connector but it is technically a solid block wall.
Or I can stick to my original plan and feed the bricklayers pizza on fridays. Thanks for any insight.
