writes BTW did anyone here ever come across the alternative design for a UK fused plug? I only met one once, it had round pins and looked fairly similar to the old 15A plug, but the live pin *was* the fuse. 'Waco' or 'Wago' plug, I think. The problem was that the live pin-cum- fuse tended to unscrew from the plug body and stay in the socket when the plug was pulled. Not exactly safe... The fuse had a threaded stud on one end and simply screwed into the face of the plug to form the live pin. -- (\__/) (='.'=) (")_(") |

Just who ever wants to draw more : than 13 : : amps from a socket anyway? : : I'm saying that is it possible, not that someone wants to do so, : but then you seem more interested in the troll rather than : actually defending your beloved ring circuits... : : It's a genuine question. What is it likely someone possesses which draws : more than 13 amps and comes with a 13 amp plug - necessitating replacing : the 13 amp fuse with a nail? Anything, it doesn't have to be in excess of 13amps, that is the ****ing point, just the non availability of a replacement fuse -*as others have pointed out also*. You wholly refuse to accept that it is terrifyingly easy for any Frank Spencer [1] style idiot to totally circumnavigate the end user protection when being supplied via a ring and BS1363 plug/socket. For the same to happen with radial circuits one would have to tamper with the panels circuit protection and not just any appliance/lead protection. : Perhaps the obvious one would be an extension lead with multiple socket : outlets. But then that can be overloaded with your favourite radials too. snip the rest of now usual trolling No, that is nothing like the problem, radials are not protected at 30amps. A radial can only be overloaded up to the maximum load of the lead (15amps) because the protection is at the panel, unlike with ring circuits were the lead is -or should be- protected by the 13amp fuse in the plug.

(IMHO) : At most Ron that is a side show, what Plowman has taken exception to is the UK regs that allow for radial circuits, and the dangers or otherwise of both UK spec radial and ring circuits. |

Some seem to think the flex rating is that where it could only just : blow a fuse of that rating. : : Jerry's favourite - 3 amp flex - has a cross sectional area of 0.5mm^. : Fusewire of the same cross section is rated at 30 amps... So a flex fitted to a plug that has had its fuse bridged out will likely start to melt if feed from a ring circuit should the appliance become faulty (short circuit), is that what you have finally grasped Plowman, BINGO! Also don't assume that all properties are protected by RCD's etc, many are still protected by slooooooow acting fuse wire. The risk is, this 3 amp flex *you* keep talking about will behave exactly like a fusible link-wire as it *will* be the weakest link, now should that flex be trailing across the carpet or some other flammable item, such as curtains or the odd magazine left on the floor next to the reading lamp.... OTOH if fed from a radial circuit protected at 15 amps (or better and more likely, via 5 amp socket off the lighting circuit) it will be the breaker at the panel and not the flex that will be the weak link. |
