        It's copper as the CU designates. If it was pure aluminum, the deALsignator would be AL Copper-Clad wire is CCAW(Copper-Clad Aluminum Wire) or CCA (Copper-Clad Aluminum)

              Can this wire be used for a lamp?

              Answer This Question

              I wouldn't recommend this for a lamp. It would be better to use 16/2 or 14/2.

                  Connecting to sound speaker with one black and one red connecting port... How do I identify which port to connect on you wire?

                  Red is positive & black is negative. Connect copper colored speaker wire to the red terminal & silver colored wire to the black terminal. Maintaining this consistancy will keep your speakers in phase.

                      Was perfect for my needs. It came zipped and unzipped very easily. The individual strands having their own color signature was very helpful as well. Easy to work with when measuring out lengths and the overall length of the spool is just right. Because the price it good and the it works so well, there is consideration of purchasing another simply to have on hand.

                      It met my needs for hooking up a set of speakers for my grandson. The best part about this wire was how the two wires were actually two different colors so they were easy to use throughout the process.
