Can this terminal handle 48v dc in parallel with 100a?

Yes this bus bar is rated for 300amp no matter the voltage so 48 volt at 100 amp will be no problem

Is this made in the United States?

Box says made in China. Ordered 4 of these from 3 different vendors. Installed 2 on HD trucks ( with 4/0 battery cables). Seems like good quality. Time will tell. Even covers had quality plastic (not always the case). Need to watch options of stud size (M10 vs M8 if it matters to you ). Would buy again.

Seems to be identical to the T Tocas brand 300A distribution box. Probably made by the same manufacturer. It has the same specs and is made the same way as my black Jamgoer brand distrubution box.

What are the posts (screws) and nuts made from?

Stainless since they are marine use
