RE: Viborg spade warning

Not upset at all. As I mentioned before, the set screws and the female threads are conductive, so the wire will be electrically connected to the body of the spade. The fork, though, is not. The torque will probably break the non-conductive surface depending on exactly what type of binding post someone has, but it's still not a good idea to have a non-conductive surface at that location. It's pretty thin/weak coating.

I will be removing it from both of the fork surfaces and the barrel. I did some more probing and it seems like the barrel is conductive, but I will resurface it anyway. If the coating was sprayed on, they probably just missed the barrel and there is likely a residual amount of coating in there (overspray).

Despite the coating, these spades have some good qualities including a solid copper body (not including the coating) and set screws. They are so cheap, so they are still a solid value. All you have to do it remove the coating.

I just read the Amazon reviews and about three other people going back to February 2020 complained that theirs were non-conductive.

BTW Duster, I also purchased the Viborg solid copper IEC inlet that you recommended and they are actually solid copper with no rose coating or non-conductive coating.
