I’ve received a message from the manufacturer of this “brand/type” of quadplex. It is 3x 4/0 insulated conductors and 1x 4/0 uninsulated messenger that can be used as a bare conductor. My question to them was is your cable assembly rated for use in conduit for a service drop to and from an ATS. Since we are a private park, the utility company does not and has not ever wanted to do any work inside the park other than where their first utility pole terminates to the cutouts, so any and all overhead inside the park is on us. With all of that being said, and the manufacturer telling me their cable is allowed in conduit, can anyone point out where in the NEC that it states uses permitted or not permitted for triplex wire, type XLPE?
I also have a copy of the lineman handbook on order so I will look in there if it ever arrives.

Please ask me questions or share your concerns before berating me with opinions about this thread or how we work here. I am open to learning but do not like it when I'm told you can or can't do something. Site your code articles not the hear-say, I've already got one stubborn boss man. Lol

For a NEC installation the conductor in the riser has to be one identified in 310.104. XLPE is simply a type of insulation and is not listed. IF the conductors are also marked with as an acceptable type such as RHW the they could be used.

The way around it, is converting to a listed wire via weatherhead into the building. I do that with underground wire I buy from the poco. Much cheaper, but cannot be used inside the premises. I bring it into a disconnect, then use thhn or rhw into the building from that point.
