When all nonmetallic sheathed cables are bunched together for distances longer than 24 in what happens to their current carrying ability?
Where insulated conductors are deflected within a wireway, either at the ends or where conduits, fittings, or other raceways or cables enter or leave the wireway, or where the direction of the wireway is deflected greater than ____, dimensions corresponding to one wire per terminal in Table 312.6(A) shall apply.
A- Discuss the following claimed arguments:
1- Guard rings are recommended in low voltage as well as high voltage transmission lines.
2- Although using bundled conductors is costly, it has many positive effects on the transmission of high powers at high voltage transmission lines.
