Would a roofed, 3/4 closed in deck area be considered a damp or wet location? Does the normal MC you buy work in this location, this Mc im talking about does have the plastic sheth under the metal shething.:happyno:
At a risk of sounding unoriginal, I have to say that it's the AHJ's call whether to consider this a wet or a damp location.
You have to look at the cable's rating to determine if it's listed a particular location - wet or damp. The presence of polyethylene wrap under the cable's armor does determine its rating; You have to check its specs.
Sourthwire's and Cerrowire's MC and MC Lite that i've seen and worked with, both have plastic wrap underneath the armor, and they are rated as damp, not wet location cables.
