A 5A current limited test on the crappy copper coated steel cable that came with one of the death-dalek camping lights.

Although current regulated to 5A it ended up less at the end due to the resistance of the cable causing the voltage across it to reach the maximum (16V) on that range of the power supply.

Cable test ends in flames

This was a 5A current test on an excruciatingly thin copper coated steel cable supplied with a dangerous product purchased from eBay. The product was notable for putting out full mains voltage on a USB phone charging port, and using non rechargeable batteries with a very basic charging circuit that could make them explode. If you really must buy cheap products from eBay and other equally safety-complacent platforms, then I recommend at the very least disposing of the supplied cables in a safe manner, and replacing them with cables purchased from reputable suppliers that comply with local safety regulations. On a typical power circuit this cable would have been a huge hazard due to its high resistance and ultra-thin wire. It could literally have set fire to furnishings in the event of a product fault, or even just using it with a higher power appliance. Sadly there are many equally bad cables with some using extra thick plastic to give the impression of having bigger conductors. The fire extinguisher I used is a Firestop aerosol unit that is a convenient size for little bench incidents.

Clive, were you anywhere near Luton Airport on 10/Oct/2023???

I bet they had an OBD Nitro diesel engine performance booster plug. It just shows you how effective they are.

No need for an inrush resistor on the "power supply" in the camping light then, the cable does that job just fine

Clive, how could you possibly know or test for this, so you know you haven’t got an f’ed cable - similar concern with those aluminium core cables 😳

bigclive

The steel core cables can be detected with a magnet, the aluminium ones need to be cut to test them unless you have a sensitive resistance meter suited to very low resistances.

This short should be turned into a short. A Youtube short video, trim it back to the moment where the actual fun starts and post it out there to warn people about those iron conductors.
