    So are you telling us this raceway that is installed on the outside wall of the building is not in a wet location?

      Really does not matter NM not allowed.

      The hanbook says that there is a 410.4(A). 410.4(A) is not in the handbook.
      I am definitely lost in what you are saying.

      If the raceway is installed a wet location the inside of the raceway is also a wet locations, there is no gray area since the addition of 300.9

        Are the coductors themselves of the type that normally would be permitted.

        Just curious.
        What does the marking on the conductors inside an NM sheath say? Answer, nothing. It is not marked, so we do not know where they can be installed. Look at 310.8(C). These are the types of wires that must be used in wet locations. Do you know what type of insdulation is on the conductors in type NM. UF comes under (C)(3) in that the assembly is listed for use in wet locations.

          I think this was debated elsewere about the wire in a NM cable. Looking at southwire specs it is:

            Yes that is what I am saying.

            I think that damp location fits it better. It does not meet the definition of wet location.

            Bob it is installed in a damp location.

            Either way no NM.

              I wish they'd change one of them! :mad: The 8 and 6 digits are hard enough to tell apart before they get rubbed off.

              The nex thing we will be told is that we cannot use NM to wire a outdoor wall sconce even if the box opening is flush with the wall.

                  There was nothing in the post to indicate that the raceway was installed under some type of cover like a porch. The post indicated that the raceway was installed on an outside wall without any additional protection that would make the area a damp location. The raceway is clearly installed in an above wet location and per 300.9 the inside of that raceway is a wet location.
                  Location, Wet. Installations underground or in concrete slabs or masonry in direct contact with the earth; in locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather.

                    I just do not believe that the wall can be saturated (full of moisture : made thoroughly wet) or better yet the conduit.

                    NM is not allowed in wet or damp locations. So we just disagree on which one it is.

                      Mike you cannot disagree 300.9 does not allow that.

                        I agree with what 300.9 says.

                        It is not saying the raceway in the above case IS a wet location. It says IF it is a wet location then the interior of the raceway "shall be considered" wet.

                        300.9 is talking about the interior of the raceway.

                        The only difference is what wiring method you can use, per 310.8

                          NEC definitions clearly describes a wet location as an "unprotected location exposed to the weather". From earlier descriptions it would appear that the conduit is in an unprotected location exposed to the weather, as such 300.9 would make the inside of the conduit a wet location.

                            Read the part before your quote. "in locations subject to saturation with water or other liquids".

                            Will the conduit get wet? Yes. Saturated? I do not think so.

                            Now if coming out of the foundation it is contact with the ground I'd call it wet.

                            Still sticking with damp.

                              My house is in a wet location. Does that make the interior a wet location?

                              So I can not use NM inside of my home?

                                IMHO wet and damp are talking about where wiring, devices, or equiment are located. Not what protects them.
