Plugs : Wylex 15A unfused piggyback, 3kW fused & 5A fused

Here we are then.... Opening the PLUGS videos with the Wylex plugs, just like I done on my original channel. :D Please note that it took TWELVE AND A HALF HOURS to squeeze this video down the phoneline, so please keep that in mind in reference to this video release being late. I was hoping for less than six hours, but given the time-length of the footage and that it is in FULL HD, this only adds to the upload time. OK, now I have that out of the way, it is now onto our video subject of today: WYLEX PLUGS. There are THREE Wylex plugs to be discussed in this video (hence the length of the video) and they are as folows: 15A unfused 'piggyback' plug (Section one of this video) 13A fused 'ring-main' 3kW plug (Section two of this video) 5A fused BS 646, 1kW plug (Section three of this video) Because there is a character limit on this video description, I will briefly describe each plug here. 15A unfused Piggyback plug. As the name suggests, this can have another plug of a lesser rating plugged into the back of it. The ratings of plug which can be coupled into the back of the 15A plug are 5A or less, so that will be the 5A plug (which will be seen later in this video) and the 2A plug (not seen or discussed here) Because this plug is unfused, protection is expected to be afforded by a 15A fuse at the consumer unit (to BS 3036, BS 1361 or even the early BS 3871 MCBs) 13A fused 3kW 'ring-main' plug. The name of this plug gives the idea that all the sockets would have been on a 'ring' circuit, known years ago as a 'ring main'. A cable would have left the consumer unit, gone around the house in a loop and then the other end of that cable re-terminated into the same connections as its other end. Because this type of circuit would have been possibly fused at 30A (to BS 3036, BS 1361 or even the early BS 3871 MCBs) the plugs would have needed to be fused. These plugs are fused at upto 13A, and to BS 1362 (in exactly the same way as a BS 1363 plug) and so therefore, different ratings of fuse were available (and still are) anywhere from 1A right through to 13A. (1,2,3,5,7,10 and 13A) 5A fused 1kW plug. This plug would have been used for small loads, like irons and small 'one-bar' electric fires and such-like. Even though these plugs would have probably been connected into a dedicated 5A circuit via their respective sockets, these plugs needed to be individually fused anyway, due to their compatibility with higher-rated sockets and the 15A 'piggyback' plug. Now, because the plugs are rated for a maximum of 1,000 watts, an appropriate fusing standard was needed which would not allow for that rating to be exceeded. Because this would have been possible with BS 1362 fuses, the obvious solution was to use BS 646 instead. Still available even now, the BS 646 fuses are available in 1A, 2A, 3A and 5A ratings. -------------------------------------------------- Because the Wylex plugs didn't really 'catch-on' outside of a particular region of the UK, and that the 13A BS 1363 plugging standard had already established as a national standard and was considered to be a "One-Plug-Fits-All" solution, the Wylex plugs and their multitude of different plug sizes, sockets and fuse types quickly fell out-of-favour, rather-much in the same way as BS 546 plugs did and the earlier two-pin BS 372 plugs. Even though today, BS 546 round-pin plugs and sockets still have specialist uses even in the domestic household, they're no longer considered 'the norm' for every-day use due to their being unfused and therefore being incompatible with the popular 'ring-circuit' wiring arrangement found in UK households. The 2A BS 546 plug and socket has seen a revival in recent years and is used in specialist lighting applications in the domestic setting, and the 15A BS 546 plug and socket is reserved for specialist circuits where a single fixed load of upto 3,600 watts may be in use, which would overload a typical 13A plug and socket. The Wylex plugs and sockets however are now largely forgotten, even in the region of the UK where they were once popular, and so therefore, they need a bit of video-time in the PLUGS videos so that they are not forgotten and lost altogether.
