I have been chatting in Discord about this with one of our German members, and it seems DEU regs on containment differ considerably from UK ones. I still think it looks terrible to have exposed bends!
I don't see how glaring it is. It's common to see such in Industrial applications both in Germany, Portugal (my country) and even China (were I'm currently stationed).
It meets and in some cases (China) suppass the regs.
In UK is different, but for me the most outrageously thing is how home installation in the UK is done, with the CUs under stairs or high in the ceeling or inside cabinets in kitchens and cables under floorboards, in some case just laying down there. And the ring circuits...
Give me the inside wall PVC pipes with singles and junction box on each room every single day and radial circuits as it's done in Europe and China. Ahh and let's not talk about the cluster fuck it is the Australian CUs (just look at Dave's video about it).
CUs should be in a easy accessible, at a proper height level without needing steps or going inside a cramped place to do any work. But if it meets regs of the country then it's just a different way of doing it.
