    I have one 'remote' irrigation valve I need to add and wire to the sprinkler controller. If I ran this cable inside 1/2" PVC electrical conduit, would this protect the cable sufficiently for outdoor use ?

      Product worked well for me

      By|Jun 3, 2020

        This wire is being used in the building of a model train layout. I bought this wire to connect the remote switches to the activation switches. The 3 conductor setup is perfect for the application...

        By|Aug 25, 2020

          I'm not an electrician but for me the flexibility of the 3 conductors inside the brown outer coating allows those conductors to move around easily. If the brown outer coating had been packed with insulation the bundled wire would be much stiffer and heavier and the insulation could impede the movement of the individual conductors in a bad way.

            I'm installing an automatic gate opener and it specifies 18/3 electrical wire. Is this the correct wire for that application?

            Should be fine for gate opener

            By|Jun 3, 2020

              Most likely not. This cable is not rated for outdoor use.

              By|May 5, 2023

                I would use it

                By|May 5, 2023

                  This wire is suitable for that application.

                  By|May 4, 2023

                    This is not outdoor wire.

                                The approximate overall cable diameter of 18/3 Thermostat Wire is 140 mils. Therefore the area of this cable is 19,610 cmils (0.01539 sq. in.).

                                    Thermostat wire is used for all of your thermostat wiring needs. Home Depot carries our shielded and unshielded security cable for these types of installations. You would need to check with the manufacturer of that particular security sytem to see if the thermostat wire was sufficient for that application.
