(1) Europlug: flexible, converging 4.0 mm pins; pins must haveinsulating sleeves.1
(2) BS 4573 shaver plug: smaller pinspacing and length, and larger pin diameter than Europlugs; sleeves areobligatory.2
(3) Several countries allow Europlugshaped 5 - 10 Amp plugs with inflexible pins; some have insulatingsleeves.3
(4) mystery plug: pin spacingcomparable to BS 4573, pin diameter comparable to Europlugs, but noinsulating sleeves.
Rating is not indicated, but because plugcord was attached to an immersion water heater, a rating ofabout 5A is likely.2
It is unclear forwhich type of socket the plug is meant, because it doesn't comply withany known standard.
Manufacturer is unknown. The water heater hasbeen bought from an eBaytrader in Lithuania. {PTB}
1 plug fit in 10A sockets and, because ofconverging pins, also in 16A sockets that have wider contacts for 4.8mm pins.
2 plug fit in BS 4573 sockets and 2-pin 5ABS 372 Part I sockets, among others still in use in India.
3 plug fit in 10A sockets, but 4.0 mm pinsmake insufficient contact in 16A sockets.
