The only things supporting that “floating” outlet/junction box is the electrical metallic tubing (EMT) connected on the right side of it and the metal cable connected on the left side of it. Neither of these wiring methods is permitted to be used as a supporting means for boxes. Section 314.23(A)-(H) provides a multitude of permitted options for securing and supporting boxes. None of those permitted options includes using EMT or metal cable. Permitted supporting means include nails, screws, braces, brackets, support wires used for supporting suspended ceilings, threaded RMC with restrictions, threaded IMC with restrictions, and flexible cord pendants. Section 358.12(2) prohibits using EMT for supporting boxes. Section 300.11(A) requires boxes to be securely fastened in place. This box is simply “floating” on air.
