Re: 1 Amp mains Cable
It depends on whether equipment or personal safety is involved. And on the equipment and whether you are working live etc etc.
I would say that any unearthed soldering iron should be fed from an isolation transformer.

Re: 1 Amp mains Cable
Product liability is what has changed. A fault that shorts the element core to the shaft could be fatal. I had an immersion heater element do that a few years back, the RCD tripped along with the circuit MCB.

Re: 1 Amp mains Cable
Its not only about safety. We had a major issue at work some years ago where the leakage current through an unearthed tip was destroying static-sensitive components.

Re: 1 Amp mains Cable
My old bench tester used to have 0.25mm flex on it! I changed it as it was quite tatty and really, 0.25mm feels far too fragile for use, especially on An iron! I used 0.5mm when rewiring my antex. It's readily available so would probably be the best option!

Re: 1 Amp mains Cable
Earthing
I never work on live circuitry I haven't got that doddery to forget yet. and as I only ever work on analogue circuitry it should be ok non earthed, I think two core is the route to go, the silicon cable seems a better compromise rather than standard 3 core cable but so far for what I want it is too expensive. days gone by you could use a bit of wet string and connect it to the ceiling light with no complaints from health and safety Thanks lads for all your input on this subject Gary |

Re: 1 Amp mains Cable
Farnell Instruments used it on much of their low power equipment. I have the end of an
RS reel of what was sold then, pvc 3-core "New" colours, grey sheath diameter about 4mm. So there must be some out there. |

I've only ever seen it new colours, I assume it was made early to late 70's and probably phased out near the 80's (going by the type and age of various pieces of kit I have seen it on) Quote:
Granted not common nowadays and I definitely wouldn't use flex that thin, but the theory is the same as using a 3a fuse to protect 3a rated 0.5mm flex. |

Re: 1 Amp mains Cable
If this cable is not taken I would love to have it for the restoration of My Marconi TF1041C
