Reducing ferrule

Not commercial. Just my house and two EV's.
Designing for 40kw. But, I think that I can get by with 30.

Very cool! Are you using DC chargers?

I still stand by my comments on 4/0 cable for a system in the back of a Sprinter van. ;-)

I wish.
Not sure if it would be cost effective , at a small scale.

If it were my van, maybe. But yeah, not for most people.

Nice thing about 4/0 cable is a rat can chew through half of it and you are still going to be ok.

I'm just not used to such stratospheric numbers. At my house, I generally consume less than 400 kW-h per month.

OK, mild climate and natural gas for heat and hot water.

Here is another example of a pin connector for larger grade wires. https://www.amazon.com/Morris-90977...52-922a-d696e27fd95c&pd_rd_i=B00UKG9S5C&psc=1

One comment for folks to remember... if the wire doesn't fit in the terminal, there probably isn't proper wire bending space either. The thick stranded ferrules for fine strand wire are one thing, but usually the reducing pins cause more problems than they solve.

Yes, a thin-stranded wire solution. a scenario where I need them is with RVs as you are often limited to low voltage which forces higher amps and large wires. And in the RV environment, you definitely should be using thin strands.

These are used on MCBs.
I can combine multiple wires inside a single terminal lug, or multiple of these terminal lugs in a single MCB port.
But obviously the cross section area is very reduced.

Not by much. Since only the top flat part of the terminal is the conducting surface. Although, i wouldn't stack multiple.

I've had to reduce and did it with a butt connector. Not ideal, but it worked.

Here are reducing adapters:

I have been looking for some of these…these look better than what I found. thank you…

OK. So I was trying to see if it was possible to fit 4 awg onto the Midnite Classic 150. I was able to barely fit 6 awg.

This morning I was on the Midnite forum. One user stated he had success with #4 AWG THHN Stranded cable.

 

[JJJJ]

Ok. Trial run. This is 4 awg THHN-2 19 strand wire. Fits perfectly. No reduction needed.
