I have a 150A panel. The Tesla Gateway is connected to the panel with a 125A breaker. The gateway has three backup circuits inside:
60A - Subpanel
30A - Downstairs AC
25A - Upstairs AC
The caps are vinyl with a snug fit on the lug nuts. You can’t pull them off by hand and need the supplied tool to remove them.
2300 miles and haven’t lost one, but two extra caps came with the set.
The caps are longer than the nuts so I needed to trim off the extra material.
They are glossy, but not too bad once they are on the truck. I also had to trim them to size.
