Re: Mains lead (flex) replacement. Legal implications.
That Oxfordshire County Council document is indeed quite easy to follow. But, as it says at the top, it is only advice. And some of its assertions are, I believe, open to challenge. For example it says
The old red, black and green colours are undesirable as they may make the product unsafe and so illegal. Really ? That sounds like an opinion to me, and a qualified one at that given the use of the word 'may'. Opinions are all well and good (I have lots) but the ones which are definitive are those of the courts. They will decide what is safe and what is unsafe. Cheers, GJ

Re: Mains lead (flex) replacement. Legal implications.
Closing back to the original post the scenario of not changing to current cord colours only becomes an issue if the new owner decides to change the plug and faced with red black and green makes a mistake in wiring it. Depending on the mistake Live chassis sets could become more elevated in potential, single pole switching may be in the neutral etc etc.
So without sound conclusions on the legality or otherwise of the subject of this debate the risk factors could certainly be reduced by using current UK standard cable colours. In particular people from North America may easily make a mistake , as an apprentice with an American company we were always taught "Black Death" referenced to plague , for the black live/line wire colours.

Re: Mains lead (flex) replacement. Legal implications.
p.s.
Forgot to mention in above post but in my opinion all plugs should be insulated pin high quality types from a good distributor. good risk mitigation for minimum effort and cost. I see that the electrical distributors already have printed labels for systems mixing old and new colours so if changing the cord is not a desired option then a wrap around label near the plug may also offer some mitigation for using old colours. Rs do these for fixed installations RS Stock( No. 487-4221) may be something similar already exists for portable appliances? pete Last edited by G4_Pete; 31st May 2018 at 8:37 pm. |

Re: Mains lead (flex) replacement. Legal implications.
No, I think it's been a very worthwhile exercise in discussing the pros and cons of a pivotal question in the usage of old mains-operated kit, and it's exercised all our minds. One general conclusion to take away is the "luck of the draw" issue as regards (heaven forfend) legal consequences and the "how far do I go" question when one could get in hot water whether one does nothing or everything. Personally, I prefer to use everything in the modern armoury- plastic insulated wire (including high temperature or high voltage options as appropriate), heatshrink sleeving, recommended practice fuse-holders, IEC connectors and so on, taking on board decades of working on kit from rubbishy (but at least compliant!) consumer goods to eye-wateringly expensive professional stuff. At least if the worst comes to the worst, at least I feel I could honestly stand up in court and say, I did my best...

Re: Mains lead (flex) replacement. Legal implications.
G4Pete's comments are another "hitting the nail on the head" excellent contribution to this emotive thread. Particularly as a significant number of vintage radio folk collect & repair/restore vintage American wirelesses & test equipment. Hickok Tube Testers, Attwater Kent, Radiola, are just a few. All 110V. Pete may well expand on the domestic electricity distribution in North America better than I. Basically in many States, the distribution is 220V Split Phase. i.e. 110 - zero - 110V. Domestic power circuitry is taken across the two 110V Live supplies(220V), and lighting/low wattage circuitry taken from zero/neutral & one or the other 110V's. I last worked on such an American installed distribution network back in 1987, in Jamaica. Where I had been asked to carry out an electrical survey. What a miss-match of circuitry cabling's colour coding, and an even worse miss-match of appliance/ machinery(it was a large farming complex with it's own small domestic housing area) flex colour coding.
Incidentally, a similar split-phase supply exists in many rural areas of Scotland. I.e. 240- 0 -240. Known officially as "Single phase, 3 wire" or "480V Split Phase". Nothing to do with 415V 3 Phase. But that's digressing. In conclusion I'll just say that there are a number of cable/flex suppliers in the UK who can supply modern suitably colour coded 3 core & safe vintage looking flex.

Simple things like fitting wiring instructions onto plugs is so simple and cheap but could make all the difference should somebody try to rewire you plug and get it wrong. As mentioned earlier disclaimers rarely stand up in court but warnings and advice, like "do not use near water" and " due to age of this equipment please do not leave powered on and unattended" could be added to a simply made "operating instructions" booklet and could save you from prosecution or at the very least lighten the outcome.

There has been a standard colour code label around since the introduction of brown/blue flex on appliances three decades earlier. I can't see one here at the moment but are still fitted e.g. on flexes supplied with rewireable plugs. They were intended to guide users fitting a blue/brown flex to a plug that might have terminals marked red/black, or L/N. These labels are the wrong way round for our application - our concern is that a user would be fitting a red/black flex to a plug with a wiring guide showing blue/brown. But a 'special edition' of this label, with the new/old colours exchanged but all other wording unaltered, might suit? |

Re: Mains lead (flex) replacement. Legal implications.
I always understood that it became illegal to sell (in the course of a business, excluding private sales etc) electrical appliances with a 3 core flex with anything other than the brown/blue/green-yellow colours in July 1970 after a 6 month transition period, and this also applied to second hand sales - dealers were expected to change the flex. Second hand shops were certainly prosecuted in the magistrates courts in the 1970s and 1980s for selling appliances with the old colours, when there were still more old appliances around.

I would be very, very reluctant to claim that vintage equipment meets current safety standards. The important thing is to be confident that the equipment is adequately safe. In the event of something going wrong then it's the courts who will decide what 'adequately' means. In the end this is a trade-off between modernising equipment to make it even more safe and preserving vintage things for whatever value they have. At one extreme are people who think that the vintage part of the argument is worthless and that the pursuit of safety is everything. I don't understand why they don't simply gut the set and put a DAB radio inside the old cabinet, having painted it with fireproof paint first 'just in case'. At the other extreme are people who wouldn't tidy up frayed wiring or replace cracking insulation. Almost all of us aren't extremists and the question then becomes 'where do we individually sit on this spectrum ?'. There isn't going to be universal agreement on that. And that's OK with me .

I would think that a small section at the bottom of the repair payment receipt could be printed in which the customer, in accepting the repaired article, is by implication accepting any modification to the cable or plug arrangements deemed necessary to conform to current regulations and practice. The customer should be made aware that this is a legal necessity, and will be done, - before the repair is taken on. I see no problem with regard to giving the customer their own old plug and cable back with the repaired item. If they decide to re-fit the 5amp 2 pin plug, and the silk-covered '30s twin flex, that is not the repairers' concern. Tony. |

Re: Mains lead (flex) replacement. Legal implications.
I wonder what they'd make of the leads on some of my HP test gear?
White and Black wires if I remember correctly. The unique Belden plug at the appliance end of the lead is moulded on, so there's no possibility of changing it.

Re: Mains lead (flex) replacement. Legal implications.
I see no reason why bits of brown and blue heat shrink can't be fitted on the ends of old cables provided they are sound.
Anyone opening the plug will be able to see both wiring codes. |

Re: Mains lead (flex) replacement. Legal implications.
In my professional work I came across several examples of "government advice" that did not accurately reflect the true legal situation. Just because a government minister says something, or a government department issues a document containing advice, does not necessarily mean that it has legal force, or that the advice is in your best interest or even legal. A couple of many examples.
In the early 1980's when satellite dishes started to proliferate, one government department (the old DTI) was urging flat dwellers to share dishes to avoid their unsightly proliferation. They were oblivious the fact that this was illegal, as a satellite dish feeding more than one dwelling was legally a cable network, and the law then in force (possibly it still is) granted local monopolies to cable operators, meaning that you would be infringing the legal rights of the cable operator who had bought the rights for your area. (This only applied to satellite reception: it was OK to share an aerial for terrestrial TV and radio reception). I pointed this out to a guy from the DTI that I met on a course, and sent him a copy of an article that had then just appeared in the "New Scientist" , where a representative of the cable companies had said that they would indeed enforce their exclusivity against anyone who set up a shared satellite dish installation. I recently mentioned in another thread the experience of a work colleague whose application to renew his colour TV licence early to save money when there was a swinging increase in the licence fee was refused in line with a direction from the minister. He took the matter to the courts, where it was held that the minister had exceeded his powers and there was no legal bar on renewing a TV licence early. He was legally qualified and was able to conduct his own case as a matter of principle, but for most people the cost of legal action would be prohibitive. To establish what the true legal situation is it would be necessary to go back to basics and review the actual legislation: Acts of Parliament, Statutory Instruments (Rules and Regulations), and court decisions that interpret them. Some legislation has to be construed in conformity with European and International jurisprudence. Few people are going to have the resources to conduct such an exercise in a private capacity. My understanding is that you cannot be prosecuted for not complying with Government advice per se, let alone local government advice, it needs to be shown which provision(s) of which Act of Parliament, Statutory Instrument, or Common Law have been contravened. However, going to law is never cheap and it is often simpler just to go with the flow. Last edited by emeritus; 1st Jun 2018 at 1:53 pm. Reason: typo correction |

Re: Mains lead (flex) replacement. Legal implications.
A number of folk have now questioned "Legality", "Regulation" etc. Folk have also been talking about the possibility of being taken to court.
In general, the UK has an aging population. Which is in no doubt reflected in our Forum membership, BVWS membership, VMARS membership, etc. I reckon that the vast majority of the vintage radio fraternity just don't have the financial status to support hefty legal fees. All over a simple choice of using modern regulated flex & 13A plugs. A number of us have advised that vintage looking modern flex is available out there. As is Bakelite looking 13A plugs. Another cautionary note, to those who wheel & deal for money - Mr Taxman, Mr NI man & Mr DSS man, Mr HSE man, etc., could all potentially use cyber technology to easily read this thread & many others. Also, we should also be able to encourage "young blood" into our fraternity, by assuring them that its not run by old risk-taking anoraks, and that we take 21st century safety obligations seriously.

Maybe I am not reading this correctly, but a moulded-on BS1363 13-amp plug could be cut off any mains lead and replaced with something else, maybe even just crocodile-clips! That wouldn't be safe nor good practice, though. Colin. |
