Distribution block questiom

**Champak** · 10-29-2012, 12:07 AM

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?

Thanks

What are you needing 80 amps for???

1/ Yes, one block designed for + & - or 2 blocks is fine. Separate grounds are fine too if clean & tight. I personally prefer a dedicated ground line back to the battery for high current distro block situations.

2/Yes, you can put a smaller fuse in the high rated blocks (assuming you have confirmed that size is available)
