All cables produced to this specification are recognized by the NEC as 600 Volt Type MC-HL and are suitable for use as described in the code. The conductor temperatures are rated for continuous operation of 90 degC, for emergency overload of 130 degC and for short circuit of 250 degC. The cables meet the requirements for application in NEC Class I, Class II and Class III, Div 1 and 2, Hazardous Locations covered under NEC Articles 501, 502 and 503. The cables are intended for use in industrial applications where aluminum armor protection is necessary. The continuously welded sheath serves to provide a completely moisture impervious barrier for the core as well as providing superior electro static shielding characteristics. The cables may be used in wet or dry applications, installed in racks, trays or aerially.
These cables have an overall jacket and can be direct buried in earth and buried in concrete.
Three conductor cables are manufactured in accordance with industry accepted practice of using three symmetrically placed grounds making them advantageous for use in pulse-width modulated cables and variable frequency drive applications.
