FRENCH SYSTEM
I can't figure out the part about having to break both phase and neutral simultaneously, then stating that rewireable fuses are no longer allowed but HRC fuses can be used. How can an HRC satisfy the "both poles" requirement?
May I hazard a guess? Same way as the requirement for simultaneous break of all three phase conductors in Sweden: Three individual fuses side by side are considered one fuse "group" and numbered as one single fuse. (In fact, group ("grupp" in Swedish) is the word used when marking cables, sockets etc.)
