Electrical cable capacity chart
WebThe new version of the National Electrical Code ® (NEC ) 2024 includes Article 311 regarding Medium Voltage Conductors and Cable. This Article was added to improve overall usability of the NEC®; in the previous versions the ampacity tables for medium voltage cables were in Article 310 while the installation requirements were in Article 328. WebThis app assumes installation in conduit or direct burial when individual insulated wire types are chosen. The app limits the final ampacity of the wire to the most conservative of: the corrected and adjusted ampacity; the equipment temperature limitation default values as described in NEC® 110.14(C)(1); or the cable type temperature limitation.
