dekay,
The hubbel outlets are plated in nickel. Isn't this a really really bad thing?
It's all about the metal bridging the wire to the Metal touching the plug. It's not rocket science people.
The alloy should probably be beryllium copper, and the coating is left to the imagination who's selling it. And then they stretch it by saying Its dipped in liquid nitrogen and they call it Cryo.
So that's it, and leave extra space around the metal so it stays cool.
It's not rocket science people.
