Big Clive on YouTube (not our Ancient Mariner) has released a video taking apart a fake Type C circuit breaker which is worth a look, but it is rather worrying what could be out there.

If you ever want to test MCB function in the sense of is there any magnetic part at all, a car battery and jump leads will get you a kA or two.

Perhaps it's best to run a section of an an electric fire element in series to reduce the current a bit. I was told off when I admitted to using Wylex B6 M.C.B.s on my 12 Volt D.C. leisure battery boat electrics. A D.C. arc may well weld the contacts together or not be quenched by the arc extinguishers I was told.
