Are the conductors within a cable in a LINKOSITY™ power system derated?
A. The connecting components are derated. When they are applied as Type TC/ER or MTW cable the four current carrying conductors of each three phase multi-wire branch circuit are derated from the 90 degree column of NEC® Tables 31015(B)(2)(a) and 310.16 to 80% of identified capacity. When they are applied as “cord” the ampacity is determined per NEC® Tables 400.5 and 400.5A to 80% of identified capacity. In both cases a 20 amp branch circuit is loaded to no more than 80% of capacity, or 16 amps – which is within the allowable derated range of operation for the 12 and 10 AWG conductors.
