DrDSL Posted March 3, 2006 Share Posted March 3, 2006 We just received our first batch of the MTS plastic wallboxes (AC-NWB3.8G). I was quite concerned re. item 7 of the install guide where they are discussing the MTS overhang width and in 7e .........."carefully enlarge with a file" etc. My experience with the guys who hang the sheetrock in new construction tells me that this sort of procedure will NEVER happen. It's strictly Roto-Zip rock & roll!I'm really concerned and interested in the experiences of others here.Thanks Link to comment Share on other sites More sharing options...
rsmout Posted March 3, 2006 Share Posted March 3, 2006 I had six boxes and didn't have any problems with their roto-zipping around the boxes. None of them were damaged. They completely covered one but found it thanks to the pictures I had taken before they got there. Link to comment Share on other sites More sharing options...
AS2 Posted March 3, 2006 Share Posted March 3, 2006 I've never used them, but isn't the METAL backbox better for that sort of construction? Does anyone know the difference and how they are supposed to be used? Link to comment Share on other sites More sharing options...
ES_Dave Posted March 5, 2006 Share Posted March 5, 2006 The metal boxes are if you are running electric in the box, such as on a LCD keypad. Those are Zigbee wireless and need power since you can't do POE. Link to comment Share on other sites More sharing options...
All Wired Up! Posted March 5, 2006 Share Posted March 5, 2006 It's a pre and post construction issue. Pre should be no problem as you are attaching the box to the stud. For post construction you need to exercise care as the outer lip that holds the box on the outside of the drywall is narrow. Link to comment Share on other sites More sharing options...
DawnGordon Posted March 5, 2006 Share Posted March 5, 2006 Dave,I hope I'm not in trouble here. I installed plastic retro boxes for the Wireless Mini Touchscreens, which are powered via AC. Do I need to pull them and install the metal boxes?Thanks,Dawn Link to comment Share on other sites More sharing options...
junebug Posted March 5, 2006 Share Posted March 5, 2006 Dawn,The only way to know for sure is to contact your local code enforcement agency. But, here's how I look at it; if there are plastic 120v boxes used in your area, then you are most likley ok. Link to comment Share on other sites More sharing options...
TrikinCurt Posted March 6, 2006 Share Posted March 6, 2006 Platic isn't against NEC, just a lot of local. We can use them here in Minnestoa/Wisconsin. Like unebug said though, check the building codes, it would be an embarassing way to fail inspection!Curt Link to comment Share on other sites More sharing options...
DawnGordon Posted March 6, 2006 Share Posted March 6, 2006 Thanks guys, it was for my showroom, so I'm not worried about inspections. Just wanted to make sure I wasn't causing any electrical problems.Dawn Link to comment Share on other sites More sharing options...
bwells Posted March 6, 2006 Share Posted March 6, 2006 I think you might find that in areas where they run conduit or BX (flexible metal sheathed) the ground is the metal conduit, which needs a conductive (metal) box to maintain conductivity. Romex cable has the bare wire that should link through the boxes and connect to devices to provide the ground. This should not be confused with the white nuetral. Make friends with a local electrician or talk to an inspector about what they require. Link to comment Share on other sites More sharing options...
