Wire terminal question

[Mike_H]

I have a bit of a unique situation. I’m installing a DC-DC charger in my motorhome. It’s a 12V/30A model. To get power from the alternator to the charger and battery bank, the blue sea circuit wizard says I need 4 ga wire. To avoid buying more expensive copper, I have a roll of 2 ga left over from another project, so I’m planning on using that. However, the charger is set up for a 6 ga pin connection (ferrule)

I see McMaster has a step down pin terminal that will “convert” a 2 ga wire to a 6 ga pin.

Is this the best method to achieve what I need to do? I think it is, but wanted to ask first.

According to the datasheet of these ferrules on Mouser, the 6ga and 2ga both have .20" ends.

Just an FYI, the step down pin terminal you reference is a butt connector.

Just make sure you are fused with a 6ga rated fuse.
