Q:I am building a residential house in Ghana and the voltage we use is 220-240 volts. Can I use these wires to wire my house? In Ghana we use guages like 1.5 mm 2.5 mm 4.0 mm 8.0 mm and 16.0 mm to connect to the high Tenssion cables .

Answer This Question

A:  12 awg wire is equivalent to 2mm. US codes generally allow 20 amps for 12 awg wire regardless of voltage (though there are exceptions) and this stranded wire needs to be in an appropriately sized conduit. I have no idea how the local codes in Ghana may differ.

    A:  This wire is rated to 20 AMPs up to 600 volts but should be installed in some type of metal or plastic conduit with a ground wire in the conduit this would be equal to 2.0 mm

      Answer This Question

      A:  It’s wet location rated cable I wouldn’t use anything else for an outdoor pool pump than this stuff. You need to run it in gray electrical conduit of course installed properly. The jacket of the cable says THHN or THWN.

          Q:Can i use this for a welding rod holder extension?

          Answer This Question

          A:  No way, it would melt

          by|May 4, 2022

            A:  No. It can't be due to fact this wire is only rated for 120V at 20 amps. Welding machines take a bit more amperage and depending on what model of machine that you have as well. You can look at at the name plate and look at what is the recommended for that that model. Hope this helps.

            by|May 5, 2022

              A:  No, it’s far too thin and only carries 20amps.

                Answer This Question

                A:  This is not speaker wire. This is for electricity.

                by|Jun 9, 2021

                  A:  No. You would need actual speaker wire for speakers (i.e. don't use regular wire like this). Home Depot sells speaker wire and it's a lot less expensive than regular wire.

                  I was easy to use as long as I put white tape on each end of one of the lengths for the neutral wire. Had to make a connection for my space heater. It's gonna get chilly.

                  It’s wire. It’s not rocket science. If It conducts electricity, it gets five stars. If it doesn’t, you send it back.
