Reducing ferrule

I've had to reduce and did it with a butt connector. Not ideal, but it worked.
Here are reducing adapters:

Way cool.
The issue is these reducing ferrules limit amp capacity to the size of the ferrule reduced side.
If it's a long run you likely get lower resistance using the bigger wire and the ferrule versus a smaller gauge the size of the reduced side of the ferrule. But for a short run likely not worth it.

All depends on the application and connection you’re making.
Don’t believe there’s one answer for each situation.
Hoo boy, that's a can of worms you're opening up there. In general, we tend to crimp and not use any soldering. In a mobile environment the solder can become an issue. I use no solder in my RV and I'm happy with that because I suck at soldering.
If a terminal involves compressing the stranded wire then I like to use a ferrule. I have used a lot of ferrules in my install. I think my terminals stay tight better when using a ferrule.
Thanks!
How do you guys do when you like connect cables to a MCB? Just twist/twin the copper up or use a ferrule?
BTW, sorry, English is not my first language, and I am especially not good with these electrical terms.
MCB = Miniature Circuit Breaker?
I used ferrules for the cables going into my circuit breakers.

If it's a set screw terminal, I use a ferrule.
If it's a clamping terminal, I don't.

Clamping terminal? Like a stud? Please clarify.

Gotcha. Thanks for the clarification.
I can’t think of any reason not to use a ferrule.
That said, I rarely use ferrules for stiff 7 strand or other low strand count wire.
For the very flexible high strand count wire I always use ferrules.
For your other question, after soldering for decades I now have decent crimping tools and only crimp the various terminals and lugs. Shrink tubing with adhesive really finishes it off nicely.
For a solder smoke fix I have to build a circuit on a through hole board, not enough skill here for surface mount.

And why don't you use a ferrule with a clamping terminal? I assume you mean by clamping terminal is what Victron Energy uses on many of their products.

I'm not sure what Victron uses. But I posted a picture of the clamping terminal above.
The conductor compresses and fills the entire terminal. Which results in more contact surface area than with a ferrule.

I can't envision a ferrule that reduces the circumference of the wire.
A pin terminal would though.

Our pin terminals offer a quick and easy connection in applications where set screws or clamps are used to make electrical contact with the wire.

I don't think they mean ferrule. Ferrules and pin terminals are often discussed together.I can't envision a ferrule that reduces the circumference of the wire.

My general unpopular comment: many people here are using far thicker wire than necessary (4/0? really?). Here's a hint: if the wire you are using doesn't fit the terminal, just maybe you are using the wrong wire.

I'm going to be using parallel 500 kcmil, to tie two battery banks together. Because I need to carry over 800 amps.

What is the load that sinks 800A?
For me, if the load is much more than 200A, I would use a higher voltage.

30kw of inverter.
48v battery bank.

That's an amazingly large inverter. I just read your profile.
What is the ultimate load that sucks up that 30 kW? I assume it's a commercial application.
