Questions & Answers

Can this be used to provide a ground to ungrounded recepticals in an old house (residential) without conduit? I.e., run along the 12-2 house wiring from the box to each receptical?

    Would there be an issue with something that draws 1000 watts?
    ByDec 29, 2024
    1 Answer | 
    Answer This Question

    This 12-gauge THHN wire is rated for 30 amps at 600 volts. A device drawing 1000 watts at 120 volts would require approximately 8.3 amps (Watts / Volts = Amps). This is well within the wire's capacity, so there should be no issue. However, it's always recommended to consult a qualified electrician to ensure proper and safe installation for any electrical project.

    question for professionals- why would you buy this as opposed to 12/2 or 12/3? I cant find much information on 12/1 online. i get the amperage, but do i need to put multiple rolls of this together to wire anything?

    Answer This Question

    To run a typical 120 volt, 20 amp circuit, you would run three colors of this wire, usually black (for hot), white (for neutral) and green ( for ground) inside of EMT conduit. 12/2 is Romex which has the three wires encased in sheathing, no EMT needed.

      NM-B cable (Romex), the most common wire used in residences, is rated for dry locations only. This wire can be combined with additional single wires of varied colors – run within a conduit – for circuits located in either wet or dry locations.

        Is this wire rated for DC? Can I use this for a solar panel?

        I've been using it to connect my solar panels to the controller for almost a year and I haven't had any problems.

              Can this be used for wiring an O-27 or O-31 model train layout? Does it matter what wire is used for hot and which is ground wire (i.e: red vs. black)?
              ByNov 21, 2023
              1 Answer | 
              Answer This Question

              For wiring a train layout it seems a bit large but it's really OK. For DC trains, color doesn't matter. There is no grounding wire

                The best course would be to verify the application with a licensed electrical professional.

                  I like the way the outer layer can be stripped without having to constantly reposition the tool.
