The wire ampacity calculator will quickly calculate the maximum allowable current through a conductor based on wire size awg or kcmil wire insulation conductor type and installation method. 2 ampacities based on 90 c conductor and 30 c ambient temperature based on table 310 17 amd table 400 5 b in the national electrical code for single conductor cables. Type w portable power cable is available in both single conductor and multi conductor constructions single conductor type w cable rhh rhw cable is excellent for portable power systems and other similar applications that may require permanent or temporary power. Or cable exceeds three or where single conductors or multi conductor cables are stacked or bundled longer than 24 inches without maintaining spacing and are not installed in raceways the allowable ampacity of each conductor shall be reduced as shown in the following table.
