2017 NEC 250.184(A)(1)
(OP)
Hello I have a question:
Assume solidly grounded neutral system. Code is 2017 NEC 250.184(A)(1). Assume feeder to downstream equipment requires a neutral and a ground.
Exception number 1 states that bare conductor can be used for the neutral for direct-buried portions of feeders. But would this not create a bad situation if the equipment ground wire was bare - and the bare neutral and bare equipment ground wire were to accidentally make contact with each other in the trench?
Could this not impose some undesired current on the equipment grounding conductor and quite possibly - on a person touching the equipment?
Am I off base on this?

Important to remember that the NEC is not a design guide. If you've got a specific application question, you'll get better answers than mine if you post more details.
Cheers,
