It is shoddy design and installation that fails to meet the basic design requirements and does not comply with the Wiring Regulations.
However I see installations installed by what I consider to be very competent electricians and each time I do see it I think to myself “Why did you do that, what was your reasoning?”.
Although I consider it completely wrong to use an under rated MCB I know it is accepted custom and practice, I also expected that I may be told that it is okay, I just didn’t expect such a highly technical argument to be put forward to prove it is not an issue.
