@Besoeker3 where are you-- can you add some light to this
Yes but I am curious as to what the box is called that the power company wires enter. I know the one above that is a meter.From the looks it seems to be 230V single phase?

@Besoeker3 ...is each RCD protecting the five breakers to its left?
At first I thought the yellow wire was a data cable, but on closer inspection, it looks like maybe a ground? If it is a data cable, you may be right.I’m not sure because I’ve never actually seen one, but relatives who have gone to rural areas of Scotland told me that the power was metered with a payment box right before the meter. So you swiped your credit card at the service entrance and pre-paid for your electricity. Maybe that’s what that extra box is.
The main switch, the red one, is on the right. The next is the RCD protection. The rest are regular breakers.@Besoeker3 ...is each RCD protecting the five breakers to its left?
Possibly. I remember payment meters but that was a long time ago like around 1950's. There may be apartment blocks (flats) in the cities where there are some but not in Skye.I’m not sure because I’ve never actually seen one, but relatives who have gone to rural areas of Scotland told me that the power was metered with a payment box right before the meter.

I believe that's correct. The fuses have a seal on them.In Besoeker3's photo you can see a similar looking shape to the one in the OP, and Besoeker3's is labeled 100A. So I'm fairly sure both of them are a set of fuses or the like, but not for use by the customer, for use by the DNO.

Maybe the main breaker in the "Consumer Unit" (service panel) is coordinated with the DNO fuses, so the breaker will trip first absent a malfunction?Sounds great but if you blow the fuse the power company has to come out... That would be a real hassle.
It would. But I don't of anyone who has had that happen.Sounds great but if you blow the fuse the power company has to come out... That would be a real hassle.
I disagree at least for the UK. Take plugs and sockets for example.It always amazes me how "non serious" (the only way I can think to describe it) European electrical installations are compared to the equipment and methods we use here in the US. Everything we do is much more substantial. Try and find a plastic panel and you'll never have open wiring like that. 100A is the MINIMUM here. That's almost like the inside of an industrial control panel.
