Yes it should be, but since I know I will only use it for powering my cell phone and notebook there is no reason to use such think wire. For example, nobody is going to be running a microwave from this wire. While you couldn't sell this, I could make it.Punx0r wrote: ↑Sep 24, 2018 2:37 amAm I right in thinking this will be used with a non-fused plug? If so, AFAIK the extension cord needs to be rated to carry at least current rating of the outlet fuse?
If you had a fused plug you could just put a 1A or 2A fuse in it and it would protect a low-current extension cord.
The issue is I need this to be as small as light as possible. I'm fitting my life into a small backpack to live maybe 6 months traveling around Asia. If I used a normal 20 amp extension cord that would be heavy and take up a lot of space.
What gave me the idea about using a really thin extension cord is when I was in Vietnam I walked into this shop "not your typical store these were stores like you would find in china town" and asked if they had extension cords.Hillhater wrote: ↑Sep 24, 2018 6:39 pmBackpacking around Asia will have far greater risks to life than a little 120v jolt !
I have frequently run 240v power lead for 20-30 meters around a garden (in winter for Xmas decorations) using just old lightweight speaker cable ! (The really thin stuff) with twisted connections etc etc
Totally un advisable , probably illegal, ..but it worked.!
Believe me, once you have seen electrical wireing in a third world country,..you wont worry about the guage of your wire.
In Asia, You are more likely to get stomped on by an elephant, than die from electricution from a DIY extension cord .
Go for it,.... live life on the edge.
I agree with the silicone wire. What I notice is that if it gets a slice it will easily peel or continue to rip open easily.amberwolf wrote: ↑Sep 23, 2018 9:59 pmThe problem with all the silicone insulations I've handled is they are soft and easily pinched or crushed open, *and* hard to see that sort of damage in it after it happens. So it can have openings in the insulation you don't know about, until you find htem with fingers or liquids.
For durable "lightweight" extensions I prefer old vacuum-cleaner cords; small handheld units have thinner lighter cords but are often still tough enough for this (meant to be walked on or run over with the vacuum brush/wheels without damage).
Yeah, it's just so that if there is a fault (cable damaged or shorted, or your laptop supply internally shorts etc) the fuse blows before the cable burns up. As it's in Asia and you're likely not leaving the cable in use unattended I doubt you'd have any issues, but I would pick PVC insulation over silicone as it's more rugged and you don't need a high temp rating (the only reason besides flexibility to pick silicone). In many Asian countries there'd be no plug, just bare wires poked into the outlet and jammed in place with matchsticks, so go nuts
In Asia, that will vary enormously...sometimes dangerously.
So you would recommend using a homemade cordset?Hillhater wrote: ↑Sep 25, 2018 8:39 pmIn Asia, that will vary enormously...sometimes dangerously.
I was used to the UK where every socket, every plug head, power board, etc was earthed, had individual fuses and/or circuit breakers and often earth leakage protection incorporated.
But even here in highly regulated australia with the same 240 v system, a fuse is a rare thing other than in distribution panels, and 2wire, unearthed, unfused , portable devices are common.
Im sure there are variations of many types, but my house definitely had 13A fused recepticals/wall outlets as well as fused plugs. The outlets were normally fused 13A for each plug socket (dual sockets) , whilst the intention was to have the plugs fused to suit the appliance draw.
STOP please. Building a extension cord is STUPID. Stupid from a safety point of view. Stupid from a economic point of view. Stupid from a common sense point of view. I challenge all of you stupid extension cord builders to build a better safer cheaper cord then this one.markz wrote: ↑Sep 26, 2018 12:35 pmYou can buy 3 conductor wires in most gauges. Even home depot will have 20 or 22awg single gauge.

If I was traveling, I would buy speaker wire which could be an option. Split a length for the 3rd conductor.

Good advise. When you get where ya going. Pull some $ out of that backpack and buy a cord that fits the receptacles in the country you are in. Better idea? Forget about electricity, phones, computers, and check out the birds, flowers, girls, food, and everything there is to see in Asia. Offroader are you a boy? Who knows...... ya might meet a nice Asia girl and reproduce
