Full Answer

A wire that has a sheathed or armored thermoplastic outer coating is able to conduct a greater load than one without. Cables composed of a greater number of wires can carry multiple phases of power safely. The power source needs to be considered when determining if the cable is able to handle the current safely. Use a multimeter to determine if proper voltage is reaching the load.
