The trailer breaker can not protect the cord because the cord comes before the breaker.
The trailer main breaker will still limit the flow through the cord to 30 amps.
No that is not correct if the end of the shore power cord in the case of detachable cord shorts out at the inlet connection of the trailer the breaker in the trailer will never see that current. The path would be from the pedestal to the inlet connection and then back to the pedestal and never reach the breaker inside the trailer. However, this is a common concern/minor issue even when using the simple 50A to 30A dogbone. The non weatherproof connections on the end on the dogbones in the links above where that 30A female recepticale is that you would plug in your existing shore power cord and the second shore power cord is on reason my dogbone has the "IN-USE" weatherproof covers which do the same thing as the cover found on all pedestal electrical outlets. My dogbone will also not lay on the ground since it's not long enough and the bottom outlet is hardly ever closer to the ground than about 2 to 3 inches.
