Is this string box wired correctly?

Hi again,

What I want to do now is add 4 more panels to my array to make it a 4s4p array.

The person I found who installs systems for the regional government was suggesting I modify the string box in my original post to accomodate the 4s4p array. He wants to use a bar to parallel everything, keep the 15A +fuses adding one more, and then put a 63A DC circuit breaker on the outbound positive/negative wires, drill two more holes in the box, and run these two 6mm^2 wires through via cable glands.

Does that sound like an OK plan to you?

Personally, I'm not sure we'll be able to find a DC circuit breaker here in Peru. My distributor said they'd have to import one, but my installer seems to think I can find one here in country.

This is what he's thinking about placing in the string box in order to parallel the multiple strings together. Does it look familiar to you? I've never seen that, but I'm pretty new to all this stuff.
