Reverse Polarity Fuses Circuit Question

Yes the reverse polarity fuses are in series with the output of the converter
Are you actually using a single voltage Parallax converter????????
Two lower cost fuses are less expensive and easier to install
Nothing more than a matter of cost for the manufacturer

IMHO A parallel connection of a fuse is STUPID at best nothing more than a cost saving that the comsumer pays for sooner or later

So is the first part of this correct about them being in series?

I understand how one fuse is in series with the one wire it is protecting, that is just normal fusing.

In the case of reverse polarity fuses where there is more than one fuse ( I suppose trying to protect the converter more so than the wire?), how can they be in series? I can see how they can be in parallel and then their little group be in series with the one wire.

But then RJ sees his single fuse being in series in that inverter?

I am still not clear if there is a special reverse polarity excuse for having more than one fuse for that job. Will they blow differently than having just one fuse? Or is it just easier to find smaller size blade fuses than big ones as was suggested earlier?

If one big fuse in series is the same thing and you already have a "battery fuse" on that same wire but close to the battery, why do you need another fuse right at the converter on that same wire?
