How they do it in Norway

Following on from my piece on Swiss domestic wiring I took a few pictures of the installation in a rented house in North Norway. The Meter and Distribution Panal are mounted over the stairwell. Both appear to have been fairly recently upgraded. The supply is 3 phase via overhead lines.

There is a 63A main switch, surge protection devices and lots of RCBOs

The circuit descriptions (it's all electric with a small wood burning stove)

There looks to have been an interesting event in the past.

  • It appears that an electrician will be positioned between a rock and a fall if working on the fuse box. Or is it just the camera angle causing that assumption?

  • Well,

    between our regs and recognised good practice you still get lots of our builder`s sparks putting CUs etc in the most ridiculous of places and that has been the way for years.

    Nice to see a Norway install  Roger
  • Not a grevling in sight! ?
  • Are they still on an IT earthing system out there?


    Curious that some of the RCBOs are 15A rather than 16A rating - I didn't think that 15A was one of the preferred ratings these days.

  • I'm surprised that for domestic use there isn't a separate front lid and front cover. I could imagine that if the lighting circuit tripped, someone might open the door and blindly feel around inside, touching all sorts of things they shouldn't.
  • Interesting they've used 4.0mm for the 20A circuits, here 2.5 would be order of the day?


    And I like that they have to specify conductor sizes, number, etc on the circuit chart. That is a simple thing that could make tracing so much easier for the following vict...err electrician

  • Thank you all for your interest. I don't know much about Norway's system but here are a few answers that I can give:

    The meter is completely over the stairwell. The distribution panel is reasonably accessable from the landing.

    The system appears to be 220/380 although I am not sure about the earthing system.

    The terminals on the components are sufficiently shrouded to avoid accidental contact.


    Best regards

  • I see the numbered labels are all about to fall off.
