NEC 314.23 (A) says "rigidly and securely fastened in place" ....
There is a metallic 4 sq. box with a twistlock receptacle being supported by one sheet metal screw (appears to be #12) and a 1/2" close nipple (could be a 3/4" nipple) , mounted on the side of a surface mounted panelboard. I would say that this box is not "rigidly and securely fastened in place". Is there a minimum size and quantity of screw or bolt to use or is this just left to the electrician's interpretation ?
Thanks.
