I mocked up some cable runs and was hoping someone could confirm that they don’t break any NEC2017/2020 rules. The wires are run along the rim joists on the upper edge of the wall right under the basement ceiling joists. The staples will be used every 3 ft. The wall itself sticks out perhaps 1” inch past the rim joist wood. This is the main reason I am looking for guidance.
On the very top I have a 6/3 and an 8/3 wire going supported by appropriate size staples to the ceiling joists. I believe these are OK to run without any support boards due to their size.
Question 1: In the middle I will have 8 NM cables run the same way the sample one is, filling every slot of the staple (the staple is rated for 8 12/2 cables). As you can see, part of the staple is sticking out past the wall by about 1 inch. It doesn’t touch the nearby heating pipe, but overall, is it OK to stick out like that or will that fall into “physical damage” category of the code?
Question 2: On the bottom you see two BX cables which are secured by special stack-able staples. The staples are rated to be stacked, however the outer staple also sticking out past the wall by 0.5-3/4” inches. Same concern – is that OK as far as the “prone to physical damage” NEC portion is concerned?
Many thanks in advance.
