2. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   Fuses for commercial or industrial power systems must have higher interrupting ratings, with some low-voltage current-limiting high interrupting fuses rated for 300,000 amperes. Fuses for high-voltage equipment, up to 115,000 volts, are rated by the total apparent power (megavolt-amperes, MVA) of the fault level on the circuit.

3. AC power plugs and sockets: British and related types

   en.wikipedia.org/wiki/AC_power_plugs_and_sockets:...

   Plugs fitted with BS 546 fuses have been optional since the original BS 546:1934 with maximum fuse ratings of 2 A in the 2 A plug, and 5 A in the 5 A, 15 A and 30 A plugs. In practice most BS 546 plugs are unfused with fused versions being unusual and expensive. The 15 ampere (A) sockets were generally given a dedicated 15 A circuit. Multiple 5 ...

   AS/NZS 3112 is the harmonised/joint Australian and New Zealand Standard for AC power plugs (male) and sockets (female). The standard is used in Australia, New Zealand, Fiji, Tonga, Solomon Islands, Papua New Guinea and several other Pacific island countries. In Argentina and China an almost-identical design is also used, but these are separate ...

   Unique to Switzerland is a three-phase power socket compatible with single-phase plugs: [55] The type 15 plug has three round pins, of the same dimensions as type 12, plus two smaller flat rectangular pins for two additional power phases. The type 15 socket is recessed, and has five openings (three round and two flat rectangular).
