The contacts behind each shield are identical, so that devices of various ratings can installed in any position. In this case, all of the fuses are the same.

The earth bar (top left) is extremely long, and has six wire holes in three groups of two.

The neutral bar above the main switch is also longer than in the example with rewireable fuses.
