I tried my best to explain the difference between B and C curve MCBs in another post, but just stumbled upon this video which, in less than 20 minutes, demystified the whole thing for me:
Highlights:
00:00 to 03:00 - difference between an RCD and an MCB, and why the MCB protects the wire but the RCD protects you and me
03:00 to 13:00 - utterly brilliant explanation of how MCBs work (and I'm astonished that we can buy these miracles of engineering for £3 a pop!)
13:00 to 16:00 - clear description of what MCB curves are and the differences between B, C and D curves
16:00 to 17:00 - where we come in, a quick intro to inductive loads and inrush currents
I learnt a lot from this vid (including how the bimetalic strip and solenoid feature on the MCB curves) and I think it will demystify a lot of electrical theory for other hobbyists,
