qwerter Posted March 13, 2022 Posted March 13, 2022 I bought a highly recommended cable and need help making 2 power cords. I have also found couple of power cable designs on one of the Russian audio forums. What are your thoughts and can someone help me with this?
Gryffles Posted March 13, 2022 Posted March 13, 2022 Try and be a bit more specific. Help with what exactly? 1

qwerter Posted March 13, 2022 Author Posted March 13, 2022 Also I would like to hear your thoughts on these designs.
muon* Posted March 13, 2022 Posted March 13, 2022 Those diagrams are not useful, they are 2 pin plug connections, and the cable used is different also.. With your cable you have live neutral and earth, the three needed for 3 pin plug connections, you need to make absolutely sure you have the correct one at each end in phase with the wall socket and component at the other end. I'd get a licensed electrician to terminate the cable for you. 1
muon* Posted March 13, 2022 Posted March 13, 2022 You will also need suitable mains and IEC? connections that will take that diameter cable too. 1
muon* Posted March 13, 2022 Posted March 13, 2022 Au wire colour codes are different to that cable also, but an electrician will do it right anyway. Here It's Blue = Neutral Brown = live yellow/green = earth https://calibreconnect.com.au/wire-colour-codes-australia/ 1
muon* Posted March 13, 2022 Posted March 13, 2022 (edited) Even looking at those diagrams again, it really doesn't make a lot of sense to me. The last one they are utilizing more conductors for the neutral line than for the live. The first one they appear to be maybe using some disconnected at the wall plug end I don't even want to think about what they are doing in the other diagram. *shrug* Edited March 13, 2022 by muon* 1
klm Posted March 13, 2022 Posted March 13, 2022 Easy to make as a straight up mains cable but time consuming to make the variants. Good luck finding someone to terminate them properly. As to the drawings, I sort of get what they are trying to achieve but as to how different it will sound, only time, patience and money will tell along with a good set of ears. 1
rockeater Posted March 13, 2022 Posted March 13, 2022 (edited) Whereas fitting power plugs is looked in Australia as some kind of danger zone, in UK a lot of equipment in years gone by was sold without a plug, and consumer was expected to fit them themselves. Main problem in making any of these "designs" is mechanical; how to fit two huge cables into a plug made to anchor safely only one of them. To succeed, you would need a very thin mains cable. As to the wisdom of running live and neutral on separate cables and connecting different strands together at either end, I have no opinion. You might consider using just one and sticking to connecting the strands as per diagram. Below is what they say on connecting the strands in such way. Translated using Google translator. The blurb from their blog says: These are not just cables, these are audio connectors unique in their sonic characteristics, which are created according to a revolutionary design. The optimal field interaction around the conductors in the audio signal transmission line is the result of the helical design of the Efa Life cable. The core of the cable is the core-concentrator of the electromagnetic field. Thus, signal energy is not wasted on propagation around the cable and, accordingly, external influences do not penetrate the signal. All Efa Life cables are not shielded, but are structurally completely protected from electromagnetic and radio pickups. The cables are produced in the FelixAudio laboratory using Efa Life technology.

frankn Posted March 13, 2022 Posted March 13, 2022 Perhaps watch this video? Obviously you need to purchase the end plugs, shrink wrap and some other items - various outlets including some vendors on SNA are approved sellers. If you build them (and it’s not too hard) remember that it is illegal to sell them without a safety certif. which costs about AUD 5,000 / per cable and results in the destruction of tested cable - the certification is designed for manufacturers to submit items from a pre-production run. Even giving them away might put you in a awkward position if they were found to be faulty. 1

Expand After reading the proposal here, I feel I must second this. I am not at all sure the wiring methods advocated in those diagrams would be allowed in Australia for an appliance power lead particularly with respect to how they would actually attach to the connectors at each end.

075Congo Posted March 14, 2022 Posted March 14, 2022 Whether you get an electrician to put power cables together for you I would not skimp on the connectors used. FURUTECH makes the best connectors in the business and they are a dream to use. Length of cable is an issue too; I would use 1.5m as a minimum. Cheers Mick 1
075Congo Posted March 14, 2022 Posted March 14, 2022 Wondering if the "certification " issue applies to all the power cables sold through SNA.......Nordost, Isotek etc. Is there some sort of certification on the cable or on the packing box? 1

075Congo Posted March 14, 2022 Posted March 14, 2022 Can't say I have seen the RCM Symbol on any of the power cords I have bought new or second-hand in the last few years. Specifically 3 EGM Power Cords (new) Isotek Premium (SNA purchase) and 2 Synergistic Research Foundation Power Cords (New). More honoured in the breach as they say! 1

075Congo Posted March 14, 2022 Posted March 14, 2022 I noticed a HiFi outlet in Sydney who initially was making power cords (Furutech componentry throughout) has discontinued offering them for sale years ago. They still sell the Furutech cabling and the plugs though. Wonder why. 1
ray4410 Posted March 14, 2022 Posted March 14, 2022 any one can go to bunnings /mitre 10/middys etc etc and buy power cable,plug tops,any no of different plug ends so where is the compliance there? 1

They still sell the Furutech cabling and the plugs though. Wonder why. Expand It's a pain, and costly to get an electrical item certified in Australia. From memory the manufacturer has to supply multiple copies of the model/item to be tested. The testing can go on for several months, often requiring minor changes and the new versions being retested from scratch. If you are not selling large quantities you can imagine the testing costs eating into the profit margin. Selling the individual components is easy and legal - with a profit margin. Let someone else do the hard work. If you are DIY and not for resale you don't have to certify anything. However you need to be careful with your insurance. AFAIK as long as you are a suitably trained technician you can build/sell a product if you purchase individually certified items such as plugs, cable etc. and you manufacture the finished product. You have to keep ensure that the certifications of the individual products are current. 4

Expand True, you can buy the individual certified items. But you can't sell any leads you make from them. Edit: Unless you are registered, as the supplier of the finished product, on the EESS Database. Edited March 14, 2022 by bob_m_54 2

Expand Completed cable assemblies are not required to be certified as such (with the exception of molded plug/socket cords). It is the individual components used to make up the assembly that must be tested and certified to the relevant AS/NZS Standards. As to power cables sold via SNA - I would estimate over 50% of them use uncertified plugs and are non-compliant with the Standards . 2
