On the Pollak 7-Circuit-Breaker Junction Box, # PK52249, the bar inside is just a mounting bracket for circuit breakers. You would connect power as needed to each circuit breaker.

The bar was also designed to dissipate excess heat generated from the items attached to the circuit breakers in the box. The box accepts studded circuit breakers like # PK54-120, # PK54-130, and # PK54-140.

The 10 amp fuse that is included with the Curt T-Connector Vehicle Wiring Harness part #C56217 will need to be the one that you insert into the #29 slot. The owner's manual does indeed call for a 30 amp fuse here but that is with the factory…

Stretching the 7-Way Trailer Connector #WG54006-043 to 6 feet isn't the best option for you. It'll reach 6 feet but the coils are fairly tight. I extended it easily to about 4 feet but beyond that it wanted to fight me. It'll loosen up…
