Gets more interesting. There are 13.8 ,4160,and 480 cables(all single conductors in this ductbank. The 480 I know 75% for terms , the 4160 and 13.8 I;d say 90% unless terms rated for 105% which i'm sure there not. They also had a 100 pair phone cable in this bank passing thru the manholes. I feel per 800.11 A this cannot be in there. (cables pass thru several manholes)This is all customer owned.
Also since theses are all feeders a Ground wire sized per overcurrent device in all conduits required. just would like to have others opinons . Thank you in advance for your imput
