Fuse Block- what is "ground bus"? (1 Viewer)

[firetruck41]

What is the difference between a regular fuse block and a fuse block with ground bus? And is a regular fuse block fine for hooking up some 10A power points to the cargo area?

I'm answering your other post too. A ground bus is just a bar or strip of metal to which multiple grounds are attached. The Bus of course is also grounded. I use a ground bus in my system, it just isn't part of the fuse panel. Instead, it's a 6 position bus that I just mounted near the battery and ran a heavy (8ga) jumper to the negative terminal. All of my accessory grounds return to that point. I bought the bus at the marine store.

Single point grounding may be necessary for some electronics*, or if you have a fiberglass body. If the body/engine/frame grounding is sound lights and other stuff like fans should work just fine when grounded to any convient piece of metal.


* This is debatable.
