In the UK you typically make a ring circuit. In the US you make branching circuits.
In the US you get: Mains -> Breaker -> Outlet 1 -> Outlet 2 -> Outlet 3.
In the UK you get: Mains -> Breaker -> all outlets -> Breaker
In the US, assume I had 65A of load on outlet 3 -- I've plugged in too many things into a surge protector. Assume a bunch of solar panels are on outlet 1.
The the diagram looks like: Mains -40A-> Breaker -40A-> Outlet 1 -65A-> Outlet 2 -65A-> Outlet 3
Now, the breaker won't trip because only 40A are crossing the breaker. But 65A are on the wire between outlet 1 and 2 and between 2 and 3.
