Securing cables to panelboards.
Securing cables to panelboards.
Quite often I will see cables, such as Romex (NM Cable) entering into a panel (panelboard) without a proper clamp or connector. This leaves this cable subject to damage and can be pulled on.
unsecured cable to panel
Cables such as Romex (NM) have to be secured to an enclosure, such as a panel, with fittings designed and listed for the cable. Those cable clamps or cable connectors may only be used with one cable unless listed for two.
2014 NEC 312.5(C).
Cable clamps or cable connectors must be used with only one cable, unless that clamp or fitting is identified for more than one cable. Some Type NM cable clamps are listed for two Type NM cables within a single fitting (UL White Book, product category PXJV).
312.5 Cabinets, Cutout Boxes, and Meter Socket Enclosures
(C) Cables.
Where cable is used, each cable shall be secured to the cabinet, cutout box, or meter socket enclosure.
See 300.12 and 300.15 for other requirements that may pertain to the cable.
