What are the cable requirement that is going from a frequency driver to the motor according to NFPA70.
Compared to NFPA79 is there additional requirement.
So far I understand that a cord to the panel could be of the following types according to UL508A.
28.5.3 The cord shall comply with the Standard for Flexible Cords and Cables, UL 62, and be one of the
following types: S, SE, SEO, SEOO, SJ, SJE, SJEO, SJEOO, SJO, SJOO, SJT, SJTO, SJTOO, SO,
SOO, ST, STO, STOO, or portable power cable type G, PPE, or W power cable.
But I do not understand what is the requirement for the cable between driver ant the motor in NFPA70 and what is additional required if NFPA79 applies.
I have tried to read the NFPA70 and if I am thinking right those hard service cord cables could be used.
In NFPA79 is it forced that it must be a conduit where the cables goes within or is it any cable that is strong enough to not be placed in an conduit according to clause?
