This #4 CCA (Copper Clad Aluminium) wire from Eric Jones (Perihelion) is thicker than #4 Tefzel copper wire. Thus I bored out this #4 terminal for a snug fit. The remaining thickness of material after boring is similar to other terminals. This terminal was purchased from Wicks and was thicker than many others. I think it may be an AMP connector.
