Distribution block questiom
1/ Is it ok to use a block that provides both ground and power, or even one block for ground and another for power? I'm a tech and work with potential high current and have always been told everything needs it's own ground. Does that not apply with things in the car? Why?
2/ My needs range from needing a 5amps out to 80amps, but a lot of the multiport blocks give ranges like 20-50, 30-80, 50-120 amps. If I have a 5amp AGU fuse, can't I still use it with a block rated 40-100 amps or so?
