Fuse size

You dont fuse for potential power, you fuse for DRAWN amperage. If you only draw 100 amps, you need a fuse slightly bigger.

A 375A fuse will pass 375A basically forever, 400A a long time, 500 probably several minutes.  You get the idea.

Better to under fuse a little than over fuse even a little bit.

So youre saying that a higher amp fuse will blow faster? How idiotic is that?

Good work.  Lob undeserved personal insults due to your poor reading comprehension skills.

The statement being idiotic doesnt mean you are. Talk about comprehension... You still need to clarify your assertion that a higher amperage fuse wouldnt hold as long.

You're the only one who seems confused.

For the intellectually impaired...

A 375A fuse will pass 375A basically forever.

That same fuse (as no reference to any other fuse was made) will pass 400A for a long time.

That SAME fuse (again, was any other fuse mentioned?) will pass 500A for several minutes. 

Unless you're a dum dum boy you get the idea.

Got it now, little buddy??

Your overuse of the comma is what is confusing, minivan driver.

The light builb doesn't shine very bright does it 

Fuse protection is always for the wire.

Generally, if there's enough of a current surge to blow the fuse in the wire -- the component that caused it is already toast.

The point of the fuse is to avoid a car fire if the wire gets damaged and touches the chassis ground.

I only used one comma.  Hopefully antique rice driver can understand.
