BS1362規格,蘇頭fuse保護作用是依此規格而定立,供電牆座背後來電的電流是高達32Amp,比電器用品所用的電 ...
這個當然...對應的好...當然是好
4A/6A/10A/13A....13A就比較普遍.....
也比較容易找到,也容易配
4A/6A..唔是個個人會配會玩.....價錢也唔平

絕對認同晶Sir所謂,
用大咗無問題最大都係13A,用細咗有可能唔夠A數燒掉,真正保護係機內fuse。 ...
用大佐無問題是誤解了,小心呀師兄,TV電源線好多唔夠13amp。

KEF的4 amp是原裝廠用的,當然不是名牌貨,只是一些制作嚴謹的大路貨。
最重要一點是規格和背後配fuse的原則,不同amp數fuse在大電器鋪很易配,名牌就當然難搵,主要是發燒友心態和價值觀做成。

雖云限流 13A,但重要睇埋電器內 份 PSU 會扯幾多A用。
電視扯電好多都大唔過 5A。TV電源線唔夠13amp唔使驚。
話時話 2A, 5A, 10A 的 25mm fuse 都見過。
返而 4A,6A 又未見過。

都岩。
但,都好似唔多見街有 15A 25mm 買。
BS 15 amp是由電箱內的15 amp mcb 限流保護,蘇頭不設fuse。

蘇頭內的fuse不是保護機內的線路,機內線路由線路板的fuse做,蘇頭fuse是BS規格下所要求,歐陸,美式,澳洲等都不同,因為供電電路不同,mcb使用亦不同,此點亦是本人經常叫人在港勿用美式的原因。
4amp是玻璃透明slow blow,6 amp是難搵,要用5 amp

好似重有一支係冷氣機用的圓腳有開關的牆蘇度。

如有我都唔會用,一就用跟機圓腳15 amp,二就改用20amp 燈曲。
至於你話"好似重有一支係冷氣機用的圓腳有開關的牆蘇度。",開關與fuse拉不上關係。

Fuses
BS 1362 fuses (for BS 1363 plugs)
Because typical British ring circuits can deliver more current than appliance flexible power cords can handle, BS 1363 plugs are required to carry a cartridge fuse, which must conform to BS 1362. The role of the plug fuse is to protect the appliance flexible cord.
When the BS1363 plug was first introduced, there were 5 fuses in the official BS1362 range which were (with their specified colour): 2 (blue), 5 (grey), 7 (black) 10 (yellow), and 13 (brown) amps. The 7 amp fuse was deleted from the official range fairly early on, though remained available for many years along with many other sizes from 250 mA upwards. The current version, BS1362:1973, allows any fuse rating up to 13A, with 3 amp (coloured red) and 13 amp (coloured brown) as the preferred (but not mandated) values when used in a plug. All other ratings are to be coloured black (this is why 5 amp fuses are now black instead of grey). Plugs when supplied separately from any appliance should be available with either a 3 or 13 amp fuse fitted, but some are supplied with both (and a few also include the 5 amp size). The fuses are mechanically interchangeable; it is up to the end user or appliance manufacturer to install the appropriate rating. Some suppliers only supply plugs fitted with 13 amp fuses to save duplicating stock.
BS 1362 specifies sand-filled ceramic-bodied cylindrical fuses, 1" (25.4 mm) in length, with two metallic end caps of 1/4" (6.3 mm) diameter and roughly 1/5" long. The standards specifies breaking time versus current characteristics only for 3 A or 13 A fuses.
For 3 A fuses: 0.02–80 s at 9 A, < 0.1 s at 20 A and < 0.03 s at 30 A.
For 13 A fuses: 1–400 s at 30 A, 0.1–20 s at 50 A and 0.01–0.2 s at 100 A.
http://en.wikipedia.org/wiki/BS_1363
以上說明BS1362 fuses用在BS 1363 蘇頭上,是根據BS規格環迴電路供應30/32 amp電流而制定,更換fuse不應以更換電線/短路方面去考慮,以為加大無事,以消費者而言,應以原廠為大原則,TV大廠要有BS認証,蘇頭內fuse是跟BS規格使用,不應隨意加大。
至於本人所提6 amp fuse是舉例而言,實際是配用5 amp fuse,例如家庭常用的電風扇。

蘇頭Fuse係無1,4,6,7,8,9,11,12A的,
只有2,3,5,10,13A,一般最平宜係13A,所以絕大部份都用13A,就算只是一隻0.5A輸出的代電器都用上13A又無機內Fuse,
玻璃Fuse只不過是機內Fuse不適合一般人用在蘇頭內,更換過程需要小小技巧所以屬於專業人員更換。
其實嚴格來講換上不是原廠Fuse就影響到保養條款,所以用家要小心處理這個問題。
