How they do it in Norway

Roger B

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.
