Re: Tunnel
I would say ?yes.? Any air that is in the tunnel (and we can all hope there will be air) will have some percentage of humidity. Changes in temperature of the surrounding dirt, however slow those changes take place, can and will force some of the moisture out of the air, and deposit the moisture on the walls and on the cables. I would call it a ?damp location,? but not a ?wet location.?

Re: Tunnel
thanks Charlie for the response
this particular tunnel is extremely dry ,air flow is continuous through the tunnel and the temp ,as far as I can tell is consistent. I agree with you and I have installed the electrical as a damp location should be installed. I was only wanting another opinion.
Thanks again,
Craig
