Profile: Kaf-Tech is a provider of electrical cable and conduit. We manufacture a variety of type MC and AC cables. The uses permitted for MC cable are governed by NEC® article 330 and any applicable local codes. Our 600 volt MC cable consists of copper circuit and grounding conductors covered with thermoplastic insulation, an overall polypropylene cable assembly tape, and an outer galvanized steel or aluminum interlocked armor. Our AC cable consists of 2 to 4 copper conductors in sizes 14 gauge to 1 AWG inside an interlocked metal armor of steel or aluminum construction. A 16 AWG aluminum bonding wire is inside of, and in physical contact with, the metal armor providing a low-impedance fault-return path required for the operation of over-current protection devices.
