Vintage radios and TVs using 'live chassis' construction techniques, especially if the mains connection was via a reversible plug/socket arrangement on the back of the receiver. that shouldn't change the live chassi issue, but the connectors are mostly not compliant - touchable live pins, no cordgrip. Can be bypassed. Not in my experience. The pins of the male connector don't protrude beyond the back of the set which has a slot with just enough clearance for the female connect to pass through so that the only time that the pins are exposed is when the connector is removed. I've not encountered a lot of connectors on the appliance, but IMLE they mostly failed. Some had bare pins sticking out, though a lot were as you say shrouded. Shrouded connectors were frequently touchable live when part-way in. Bulgins were usually unscrewable without a tool, so require a mod to stop that And that circa 1910 hotplate? It had 3 sticking out pins connected to differing points of the element. The mains lead had 3 separate 1 pole sockets on.. The power level depended on which pins the L&N sockets were pushed onto. The remaining pin was of course live. Hopefully you pushed the socket on the 3rd green wire onto it, and didn't foolishly connect it to earth in the plug. Of course there was no earth conection on the hotplate. But even with all 3 connectors on you could still touch the live bits. I've vever come acros a connector without a cord grip (usually moulded serrations in both sides so that the flat flex is firmly clamped when the fiving screw is tightened. I've seen tons of old mains connectors that lacked an effective cordgrip. It's a frequent problem Uninsulated control spindles so that, if the felt washer between the knob and cabinet is missing, a fine probe in the gap could come into contact with the potentially live spindle, depending on the design of the knob. If the knob isn't secured by an inaccessible strong spring clip, the securing grub screw can also be contacted with a suitable probe. Fit felt washer, cut one if necessary. A soft epoxy resin over the set screw. I was thinking of a drop of molten candle wax! not robust enough NT At the rear, again a sutable probe through the ventilation slots could contact the chassis or other live parts. as long as it's not touchable. If it is, affix plastic netting. But would any of these result in a PAT fail? the connector usually No, for the reason I stated above |

Bill your point that not being harmed equals safe certainly was. I think we can agree on that. My point being twofold. One, that where a risk has been shown to be effectively non-existent by the situation occurring many times without harm befalling man or beast then it should be treated that way, and two, absolutely, as long as the number of successes is high enough that having assessed and used countless mains extension leads without harming the afore mentioned man or beast, I am de facto qualified to test mains extension leads. that is the nonsequitur. You may be very well qualified to test them, but not because no-one has gotten hurt. NT |

Loads of historic stuff hasn't a gnat's chance in hell of passing a PAT test. OTOH some was very progressive on safety. Folk whose hobby is restoring vintage sets frequently complain about the loss of rare items because most charity and second hand shops refuse to accept them because they have no-one able to PAT test them or simply because the mains lead has red/black insulation, although it is perfectly legal on any set built pre-1970, so these sets go to the tip instead. Perhaps the solution is if that is your thing, to visit all the likely shops and leave them a card saying if you get any donations of this kind of kit, please let me know and I will come get it. Generally thy won't do it as it leaves them liable. NT (or failing that, offer to do free PAT testing for them on the understanding you can keep any "interesting" stuff that won't pass the test). |

Some had bare pins sticking out, though a lot were as you say shrouded. Shrouded connectors were frequently touchable live when part-way in. I spent 9 years repairing radios and TVs from 1960 - 69, so saw a wide variety of sets dating back to the early/mid 50s from numerous manufacturers and never saw a set with exposed pins. The connectors were all variants of a 5A 2 pin flex connector, which is exactly what we used on the bench - the manufacturers special version never left the customer's home. There was a variant we occasionally saw, a polarised connector with one standard size pin and one thin pin but a length of matchstick in the appropriate hole of the female bench connector resolved that problem! By the end of the 60s, all manufacturers had moved away from the detachable mains lead concept and new sets had integral leads. 50s TVs were the first things I tried to repair, but mostly my experience has been with anything other than TVs. Largely various audio stuff. Bulgins were usually unscrewable without a tool, so require a mod to stop that H yes, the Bulgin P73 and P74 and the later miniature P360 - I remember them well! What form does the mod take? It's a long time since I even saw a Bulgin. A small screw somewhere stops it unscrewing by hand, but I don't recall just where the screw went, other than through the plastic thread. I've seen tons of old mains connectors that lacked an effective cordgrip. It's a frequent problem Yes, I can recall a number of plugs that were expected to be fitted with cables much thicker that thin twin flex that left a lot to be desired! yes, and a lot with what are perhaps best described as unsuccessful attempts at cordgrips. Fit felt washer, cut one if necessary. A soft epoxy resin over the set screw. I was thinking of a drop of molten candle wax! not robust enough Fair enough. I have, on very rare occasions, come across knobs with a short plastic grub screw fitted on top of the metal screw but I doubt you could find them these days and, of course, they would need BA threads! Thinking about it, the knobs must have been specially made too as you wouldn't normally expect to find a threaded hole in the plastic part. Turns out it's quite practical to duplicate old knobs now. Silicone to make a mould + resin. NT |

I suppose the presenter was trying to avoid any blame if a faulty lead had been provided due to her requiring one for the presentation. Avoiding liability by being seen to be taking every step to ensure safety. Seemed an overkill. If a faulty lead had been provided and the equipment used was class 1, the lady would have been at a much higher level of risk, in fact the risk may be a certainty of shock or electrocution if the circumstances were right. Taking every reasonable step to ensure safety isn't an overkill at all. It's to be expected and anything else is negligence. Methinks the lady would be better off finding other venues if what should be normal adherence to current practices is "overkill". I hope for everyones sake the heating to the hall isn't by gas!!

Old stuff often really does need that 3A fuse if it's to be safe. But it has to come up to the recent standards that;s why you have tp replace the cord My 1937 mains lead is still ok & compliant. Many that age aren't of course. and check for earthing on antique light fittings, although I cna think you can leave them as is providing they can't be connected up easily. Or for specialsed places like museums. Can be an interesting question how one can make noncompliant antiques safe. It's quite easy yuo just make them comply to the necessary safety rules. Like the vulcan bomber, remove the nuclear weapons and all weapons and makew sure that no one can just jump in and take off in it it is then consider safe, but it;s still an aircraft that can be seen and viewed. lol. How would you make a live chassis curtain burner safe then? No idea as I haven't one to make safe. I couldn;t have made the Titanic safe either unless I had teh authority to refuse to gibe it a sea worthy license or whatever ships are given. |

He'd already mentioned them earlier on the thread. I'm not sure what you mean by 'them.' Isolating transformers. Fitting an iso won't make such radios pass. But would mean that they are safe to use. Curtain burners were so-called because they were prone to setting curtains alight. The mains lead worked ok as long as it wasn't coiled & covered with cloth, but do so & the resistance wire in the lead caused a fire. So no, you can't make one safe by fitting an iso, it would still be a fire hazard. A safe way to drop the voltage is also required. And since you already are using a transformer... NT |

And few had their radio under the curtains anyway. There may have been a problem at times with just one power point per room, but now that we dont have that anymore, one of those antiques with an iso isnt going to be setting fire to the curtains anymore even if the cord does catch fire, Corse it could set fire to the carpet now instead, but thats got nothing to do with electrical safety. So no, you can't make one safe by fitting an iso, it would still be a fire hazard. Bull****. A safe way to drop the voltage is also required. And since you already are using a transformer... Still got the problem with the cord catching fire. In fact a worse one given the higher current. |
