    I can't help you with the pd-k or pd-x.
    Obviously the 12/2 w /g NM is the standard designations we are used to seeing.
    12 gauge, 2 conductors with ground.

    Thanks Jim, already knew that, and was wondering what the other meant.

    I'm sure you already tried searching but all the pages that I tried to go to come back as not found or broken links.

    Phelps Dodge was originally a very large mining company which mined copper (mainly copper) and began manufacturing copper wire.

    As I recall, Phelps Dodge wire manufacturing was bought by or combined into General Cable which is now owned by Southwire. Southwire is now the manufacturer of Romex(R).

    PD-X

    The PD stands for Phelps Dodge, the X is the type of NM cable, similar to the designation NM-B.

    Starting with the above information I found the following link:

    From the link in my previous post:
    - PDX TYPE NM WIRES - - Application
    - - - Non-metallic sheathed cable for exposed or concealed installation not exposed to excessive moisture or dampness
    - - Specifications
    - - - UL 719
    - - - PNS 35-2

    UL 719: http://ulstandards.ul.com/standard/?id=719

    The referenced UL 719 is the UL standard for NM cable.

    The link also included a link to a download document - that link is old and no longer goes to the document. I tried searching for the document itself but did not find the document.
