Those single end supported secondary connection bars in the pad-mount transformer video look dodgy as hell. From the way they were moving when he was using the spanners reasonably close in to the support, if fully populated with 7 loads I can see them easily bending onto the adjacent bar or snapping off! They would probably be getting more support from the tails than from the transformer bushes.

Secondary breaker? Don't the transformers just have a fuse on the primary? The pole mounted sort do, I've never looked inside one of the pad mounted kind that feeds my house. One transformer normally feeds several houses so it will be fused considerably higher than what is needed to supply 200A.
I can't answer for other locations, but our utility has a primary fuse that is fairly large (10 - 15 A) at 7200 V to protect the distribution network.  The transformer has a mechanical breaker inside the can that can be operated by a lever on the outside of the can.  That's also a handy way to shut off the LV feeder without having to mess with the HV fuse.

They look a bit weird but you don't tend to hear about these transformers failing and there are millions and millions of them, I know of 6 or 7 on my street alone. The wires themselves will offer a good deal of support, I've installed service panels a couple times and 4/0 aluminum cable is sturdy stuff. Once you bend it into place and terminate it on the bar it will work for you rather than against. It's coming out of the ground so it's going to be firmly anchored and not moving around.

Steve Lehto, the long-winded Youtube lawyer, discussed this case in his channel.

You can multiply, but you needed to divide as well :)
