exposed ground conductor riser

[cvirgil467]

We are installing ground bars in electrical and telecom closets. There is a dedictaed ground riser connecvting these ground bars back to the main service ground.

Does the ground riser condcutor need to be installed in a raceway. I read 250 and canlt find anything that says it need to be installe in a raceway.

I can't find anything either.

In fact, it may be better not to install this bonding conductor in a raceway.

Don't need to, but if you do install in a raceway, I suggest PVC.

Good find. Now the question is, what does "subject to physical damage" mean?
