you trying to make me out racist now.!!!!!!!!!It may not be "Environmentally Friendly" ; however, as has been posted previously; Suppliers are tending to not keep stock of 2 core SWA. So what would YOU do? Put the job off until they CAN get you some; or buy the 3 core, and strip 1 out to use as a single??(make sure you remove the black one! Steptoe doesn`t like Black `uns) :^O
And, to address the Environment issue; if that is the cable we are being led toward by wholesale supply, that is the cable we have to use.
Deal with it!
