The correct answer is that to protect the receiver ...

Quote:You thought right, but too short.I thought that the receiver could not draw a current greater than that on the rating plate ...

15kVmaciej wrote:The previous standard offered fuses in plugs, which was a more expensive and therefore niche solution. With the switch to a newer system, fuses became standard.This solution was born in the 1940s, when material savings in installation works were sought.

There is a profession where such plugs have a maximum service life of 2-3 months and are neutral broken. Such a purely commercial use with full health & safety + risk assessment approval.And get it into your head that these plugs are not applicable at construction sites because there you cannot use receivers with such a plug.

Quote:... at one time SEP recommended to connect the phase on the left side. As a result, when we connect the plug with a fuse in Poland and the fuse is on the neutral wire, the insulation of the device is damaged and the phase wire is connected to the earthed housing, short-circuit or overload current will flow and the fuse in the plug will not work.

In Poland, it is not standardized on which side the phase should be, and the SEP once recommended connecting the phase on the left side. As a result, when we connect the plug with a fuse in Poland and the fuse is on the neutral wire, the insulation of the device is damaged and the phase wire is connected to the earthed housing, short-circuit or overload current will flow and the fuse in the plug will not work. The use of such a fuse is harmful because it misleads the device that the device is protected by a fuse in the plug. The use of an RCD in a TNC installation, for example, is similarly harmful.
TL;DR: UK BS1363 plugs contain a replaceable 3–13 A ceramic fuse that cuts fault current roughly 10× faster than a 32 A breaker [BS1362 spec]. “The fuse protects the appliance, not the wiring” [Elektroda, 15kVmaciej, post #14429620] Swapping to a Polish Schuko plug is legal if wire colours match and an RCD backs the socket [Elektroda, kkas12, post #14439875]
Why it matters: Correctly handling plug fuses avoids nuisance trips, fires, and voided warranties.
• Standard BS1362 fuse ratings: 3 A, 5 A, 13 A; rupture at 135 % in ≤1 h [BS1362 spec] • Typical BS1362 ceramic fuse price: PLN 1.5–3 each, pack of 10 [Farnell 2023] • UK ring-final circuits often protected by 32 A breakers [Elektroda, Anonymous, post #14429620] • Polish Schuko plugs accept 1.5 mm² conductors rated up to 16 A [PN-IEC 60309] • Fault energy let-through of 13 A fuse ≈ 0.4 A²s at 100 A fault [IEE Guidance Note 2]
