Is there a correct way to install plaster rings on a 4" sq box per the NEC? I seem to remember an electrical inspector requiring that all plaster rings to be installed so they would not fall off in the event the screws were not tightened. In more laymans terms they should not be installed upside down. Can anyone provide what part of the NEC requires this or was this just an overzealous inspectors personal pet peeve.
Thanks
