The interior of PVC-jacketed MC is immune to moisture thanks to a covering that runs the entire length of the conductor. In direct-burial applications, it also permits the conductor to be in direct contact with the ground.
RomexTM is rated to be affixed to the studs exactly as is; we don't pull it through conduit. If conduits for pipes are already in place, simply remove as many individual wires as required. It also requires considerably smaller piping.
0:57 5:59It doesn't state we can't use it inside of a conduit; that's all it says. Therefore, if we're in a garage,
Safety: Because of its metallic coating, MC cable is safer to install than Romex. This sheath lowers the possibility of unintentional wire exposure by guarding against shearing and puncture. Romex sheathing is less safe unless it is run through a protective conduit because it is readily pierced or sheared.
Type MC cable runs that are exposed must closely adhere to the running boards or building finish. Installed beneath floor or ceiling joists, type MC cable needs to be protected from physical damage and fastened at each joist [Sec. 330.15].
Type MC cable must be supported and fastened using staples, cable ties that are marked and labeled for support and security, straps, hangers, or comparable fittings, or other authorized devices that are installed and intended to avoid damaging the cable.
Installing Type MC cable through or parallel to furring strips or framing members requires protecting it from physical damage caused by nails or screws by leaving a 1¼-inch space between them, or by installing a suitable metal plate in compliance with Sec.
When correctly terminated at both ends, the insulated grounding conductor included in MC cable provides a dependable return channel for fault current, allowing the overcurrent device to carry out its protective function.
Every 6 feet of MC cable needs to be fastened at intervals of no more than 6 feet. All boxes, cabinets, fittings, and other cable terminations must have cables with conductors no bigger than No. 10 AWG fastened to them within 12 inches. Every six feet, an MC cable needs to be supported.
The DRS18100 staples are UL listed and in compliance with the National Electric Code. They are permitted for use with single or double-stacked NM sheathed wire, including Romex and MC (metal clad) cable (UL 406A). Additionally, low-voltage cables like coax, CAT3, and CAT5 can be used with them.
