This happened last month and we (guys at work and myself) have varied opinions:
Our new guy was installing a generic spot light/motion unit over his neighbors garage. The unit came with the floods, motion unit, backing plate and a round FS box (a DIY store generic package deal with UL stamp). The box had a threaded "boss" in the center of the back to thread in a connector. He ran the wire thru the attic, drilled a 1/2" hole thru the fascia and put the NM-B thru the hole and into the box. To avoid drilling a 1 1/4" hole (big enough to swallow the connector) in the fascia he pushed the wire in the box, put a connector on the wire inside the box, tightened the 'pinch' clamp, spun the box on the connector to make it tight, then mounted the unit. Now we're all scratching our heads. We all said this is a violation but since we've been talking about it, nobody can come up with a section. Now we're wondering if this is a violation or just something we've always done a certain way.
We have looked at this as follows:
1) Violation of 'install as per instructions from the mfg'. Prob is, there are no instructions, not even any pictures (Arlington industries made this connector). We looked on the box, in the catalog and went online and can't find anything from the mfg that tells which way the wire goes in the connector or the connector in the box.
2) Box fill violation: no, there's nothing but a single 12-2 in an 18" box.
3) Inability to adjust the pressure after installation. Actually it's more accessible than if it were outside the box, we just need an offset screwdriver.
Your opinion? What are we overlooking? (or did our rookie come up with a shortcut we all should have thought of years ago?)
