Hey everybody, im new to this site and would appreciate a little help. I am working on a nuclear densomiter installation and am installing 10 level transmitters on a vertical tree around a vessel. I have two conduit runs going up the tree, one run will carry the AC wires and the other run will carry the discrete and analog wires. The 10 devices will be connected to the rigid conduit via liquid tight flex. I ran my continuous bonding conductor in the AC run, it is connected to the bonding screw in each device, and the other end is connected to the bonding bar in the junction box. I didn't run a ground in the control conduit but now i am being told i have to because the conduit is connected to the devices via flex. I don't really see the need to run a piece of ground through just because it is flex, the ground would essentially be connected to the same screw as the ground from the AC run. I also bonded the control conduit at the junction box. Is this correct?
