This product does not meet the advertised specifications. It is advertised for 8 AWG wire but is actually rated for 10-12 AWG. Fitting shown with red insulator which is the industry standard for 8 AWG. The product shipped has a yellow insulator which is the industry standard for 10-12 AWG fittings. An 8 AWG wire will not fit into this fitting without cutting a few strands of wire, which is unacceptable. I returned the first order for the above reasons because I accidentally sent the wrong item and received the same item as a replacement.
