Metal sheathed cable with jacketed, cabled conductor subassembly
A Metal-Clad (MC) cable assembly includes a core having a plurality of power conductors cabled with a subassembly, each of the plurality of power conductors and the subassembly including an electrical conductor, a layer of insulation, and a jacket layer. The MC cable assembly further includes an assembly jacket layer disposed over the subassembly, and a metal sheath disposed over the core. In one approach, the subassembly is a cabled set of conductors (e.g., twisted pair) operating as class 2 or class 3 circuit conductors in accordance with Article 725 of the National Electrical Code®. In another approach, the MC cable assembly includes a protective layer disposed around the jacket layer of one or more of the plurality of power conductors and the subassembly. In yet another approach, a bonding/grounding conductor is cabled with the plurality of power conductors and the subassembly.
1. A metal clad cable assembly, comprising:
a plurality of power conductors adjacent a subassembly, wherein the subassembly includes a set of conductors, and wherein each of the plurality of power conductors and the subassembly includes an electrical conductor, a layer of insulation disposed directly over the electrical conductor, and a jacket layer disposed directly over the layer of insulation, wherein the layer of insulation and the jacket layer are different materials from one another;
an assembly jacket layer positioned between the subassembly and the plurality of power conductors, wherein the assembly jacket layer is disposed between the subassembly and one or more of the plurality of power conductors, wherein the jacket layer of at least one conductor of the subassembly is provided directly adjacent the assembly jacket layer such that no element is present between the assembly jacket layer and the jacket layer of the subassembly, and wherein the jacket layer of each of the plurality of power conductors is provided directly adjacent the assembly jacket layer; and
a metal sheath disposed over the core.
2. The metal clad cable assembly of claim 1 , wherein each of the cabled set of conductors is configured to conduct a voltage between zero (0) and approximately 300 Volts.
3. The metal clad cable assembly of claim 1 , further comprising a layer of tape disposed around the plurality of power conductors.
4. The metal clad cable of claim 1 , further comprising a bonding/grounding conductor within the core.
5. The metal clad cable of claim 1 , wherein the plurality of power conductors and the subassembly are cabled together.
6. The metal clad cable of claim 1 , further comprising a layer of tape disposed around the plurality of power conductors.
