Some of the pictures look fairly familiar to the continental European eye, except for the IT-specific bits.
Do you have any idea why in one picture some of the fuses are yellow instead of white? I've never seen that before!
The large number of RCBOs (GFI breakers) is also unusual, in most parts of Europe they're still ridiculously expensive!
For the fuse color I have no idea. It is strange. Perhaps a main or higher amperage fuse?
My understanding is that in Norway GFCI/RCD breakers are mandatory. From all the Norwegian panels I have seen on the net most if not all the circuit breakers are RCD/GFCI type. Its interesting, because through out the rest of Europe its normal to have a 'main type RCD breaker' where one 63 or 100 ampere RCD breaker feeds about 10 regular breakers thus protecting many circuits. Its cheaper, but one ground fault shuts down more than one circuit.
In My Opinion, I like what Norway has going.
