Here I picked up surplus Lenovo computer power cable from my work. I wanted to show you the plastic cover for the plug that they used during shipping. This is typically using the AWG 18 gauge stranded wires.

This reminds me of when my grandmother received a brand new toaster a few months back. She called me and said that she couldn't fit the plug into the socket so I had a look and it turned out she didn't realise there was the plastic cover on the prongs.

Its supposed to be good cable for computer uses (up to few Amps)

I had used some of these cords for a few undercabinet flourescent fixtures by cutting off the IEEE connector on the end. Not sure what the connectors for HP are called, it looks somewhat an Mickey Mouse ear connecting arrangement for the power adapter hole.

Long live the great old 20th century quality in electrical & lighting products!

I have lots of these --like a whole copy-paper box full-- ... not sure where they all even came from.

Its All For The Christmas Lights...

Being IT guy i have several 10's of those laying around. In addition to some 10's VGA's and several miles of Ethernet..

Most of the power cables are with our Israeli 3 pin plug, but we get many US and Schuko/France ones (the plug that combines Schuko and French standards in one, which is used in most of Europe) - As those are often included with PCs and cannot be used here (if following the rules, that is. In reality the Schuko's can go in most newer IL receptacles - Phase and Neutral connect alright but the Earth does not get connected, so its a quick way to get a pichu or damage equipment). The deal is, that most IT equipment comes packed in boxes as-is (as it was imported), with US or EU cable included inside. The boxes have a hole that allows additional stuff to be thrown in on the way (warranty cards, power cables, CD's) but nobody would open the box to remove the other cable which is allready there. Occasionally an Italian 10A or BS1363 cable can be found



The cables that come with PCs (and generally, the ones that have the gauge printed on the cable) are usually of good quality

The cables that come with "$20 case with power supply bundle", however, are downright scary sometimes

Back in 2008ish there was a big batch of some especially "wonderous" cables that somehow came into the country... My first encounter with them was when i got one that didnt work, so i decided to check whether the broken wire is in the IEC320 connector - So i would cut it off and use the rest of the cable for something else. Cut it off, came to strip the wire...

They contained wires made with a few very thin (way thinner than any standard gauge) and Blackened from oxidizing strands, of a metal that feels too springy for Copper - Probably had Steel in them. They were allready broken up in few places along the cable to begin with - The current goes from strand to strand around the places where each is broken (in a different spot). The isolation was not great either - I could strip it by folding tightly and pulling with bare hands

But just for fun and gigs, i put this cable (with cut off IEC320 end and some more of its length) for a test with small load - Wired a 8W T5 Fluorescent lantern with it and plugged in. Comes out, the cable is broken in atleast 3 other spots, and i could play with it and see when the circuit is complete, arcing in series with the lamp, or broken completely...

Then started the accidents. The cable works fine first, then somewhere a strand gets broken and the thing starts arcing - somewhere inside the cable - in series with the PC (which is very supportive for arcing, as there are big filtering caps in the PC power supply, with big inrush current after a momentary drop). A hole burns in the cable over the bad spot and sparks just shoot out. Seen a few of those. One at home of a friend, he got a fireworks show from the HTPC - cable was in use for about a year. Few others in the hands of scared users, some of which also got a nice burned hole in the carpet. In 2009/10ish i read a news article about a house fire that was traced to a PC - No usefull details were provided in the news, but i think it might well be another one of those..

And just a thought. This cable could have huge resistance in it, probably on the order of a few Ohms distributed over its length. What if a PC (or the cabe itself at the PC end) shorts, then the cable would limit the current enough to prevent a 16A breaker from tripping - Which means, the cable would become a long heating element..

So just in case, big stock of good cables is good if you try to pin down and replace any of those cursed cables. Though 8+ years later, not many of them are around anymore



The Mickey Mouse Clover leaf connector is the smaller IEC320 C5 which is used on most notebook adapters. Not HP specific. Its Dell that had proprietary connectors in some adapters

Wow, that is terrible Ash.

I'm sure that UL (Underwriters Laboratories) will not approved these cables for the safety standard.

Pretty, please no more Chinese failure.
