NEC Table 9 Design Criteria Question
NEC Table 9 Design Criteria Question
(OP)
I have one more question, it may sound stupid to others, but I will give it a try for my understanding. The NEC Table 9 is entitles as "Alternating Current Resistance and Reactance for 600V cables, 3Phase, 60Hz, 75 Deg C, Three Single Conductors in Conduit"
Are these installation and temperature conditions to be statisfied in order to use the Ohms to neutral impedances in our V drop calculations?
If I have more than three current carrying conductors in the raceway, or say I chose a 60 Deg C or 90 Deg C conductor temperature, will these impedances still going to be valid?
Thanks
