Niko: I have written quite a few red stickers for non-conformance; as I said above...two choices, receptacle or breaker lock-out.
A few guys can't seem to understand that the CB lock-out is NOT the clip type to prevent inadvertent shut down of select circuits. Nor is it a LOTO device, it has to remain on the CB, not removable. A recent final on a McMansion took three (3) trys 'till the right item was installed.
