How do fuses in series react?

How do fuses in series react? If I had a 60 amp fuse at the battery, then another 60 amp at the positive distribution block, and another 60 amp at the negative distribution block, the over all rating would still be 60 amps right, and not 180 amps, and at least one would still blow at 60 amps of current draw. I covered all this in basic electronics, but that was 10 years ago, and my retention seems to have deteriorated. Sorry if this has been covered before, but I searched for about 30 mins, and couldn't find the exact answer I was looking for.

Except in a 12V application, there is no "ground". Technically, it is a current return path or a negative. While (again, technically) the neutral and the (earth) ground are the same thing in the US, DC distribution functions very differently than 120V AC distribution. There is one ground (return) in DC, but on the AC side, the ground is attached to the chassis of the device for protection. (This is not so in a DC circuit - without a negative, the device simply does not work) If the "neutral" fails, the power coming into the appliance through the "hot" side is shorted to earth ground, rather than into you. There is NEVER (or at a minimum, should never be) current on the ground leg in an AC distribution system, except in a fault condition. Even if the device continues to function, you are safe, BECAUSE of the "earth" ground. The REAL reason you never fuse the ground is because IF your ground fuse blows, but you B+ fuse does NOT blow, all of a sudden ALL of that current is now looking for another path. That path is generally your RCA cables. Most devices today do use isolated grounds on the signal wires, but many do not. Do you think the ground traces in your deck or amplifier can handle 60A of current? I'll answer that for ya - NO. It's gonna burn something, and it's gonna be expensive. Get rid of that fuse block in your ground NOW... This is also the same reason you should always make solid ground connections BEFORE powering your devices up!It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
