We do a lot of Block wall work for schools, jails and other projects. A typical rough in for devices on these walls would consist of PVC conduit with a device box with a PVC 90 turned out at the top for the stub out. I have seen many different methods on the stub out of the PVC at the top of the stub. Some electricians cut the PVC off even with the wall and put the box knock out over that pipe. Some electricians leave a very short PVC extension of the 90 out of the wall and then mount the box over the extension. Some turn the entire 90 out and use the male adapter and secure the box to the wall with a short conduit stub behind the box and tap-con. We have not ran into any issues with the local inspectors with cutting the PVC off and not using the Male Adapter. This may be that they are being lenient towards us, or don't know if its a violation , or if the NEC has made provisions for this. Obviously it is of great benefit to sheer the pipe off even with the block and keep rolling as it is a labor saver. However, I realize that if this is not the correct method we need to address it now to stay out of problem areas ahead. Thanks for your replies..
