Isn't this the most popular type of RCBO used across the UK in the electrical consumer units? Are there any special requirements to choose specifically DS201 instead of DSE201?

Tony S, I understand that part. However, my question still remains - why would you choose one type over the other? I remember reading somewhere that electronic RCBOs are less reliable, but I do not recall exactly why.

I am not sure we are talking about the same devices. Let's take for example ABB's DSE201 and DS201 series. One is identified by the manufacturer as electromechanical and another - as electronic.

Why would you choose electromechanical over electrical RCBO or vice versa? Hager, ABB and other manufacturers offer two types of RCBOs. I would like to know what are the pros and cons of each.

Yes, it is an old object. I am not sure what exactly confuses you. By the way, what about my question #4? Can anyone please clarify if those calculations are correct?

I am sorry I made a mistake. By "cable" I was referring to 3 separate single core wires. To my excuse, I was reading quite a lot of technical documentation lately with regards to this matter and all the examples were talking about the PVC Twin & Earth. In my case there will be no one...

I am sorry, but what did I do wrong? Did I ask too many questions?

There is a 6mm2 aluminium cable connected with a 4mm2 copper cable in a radial configuration. They are both buried in masonry, their total length is ~10m. I cannot think of any correction factors (no thermal insulation, no increased ambient temp etc.). 1. Can I use a 32A MCB to power that...
