| Apr 2, 2019 at 17:48 | comment | added | David | So here is more detail. @PeterCordes the clock uses 9 watts of power, and I don't really plan on moving it around that much, so it's just going to sit on a desk for most of the time. I am currently at university at the moment and don't have access to hardware such as solder (although I am not confident at soldering, nor any complicated electrical work.) As of now I have applied several turns of electrical tape, and so far nothing bad has happened. Long term, I may replace the plug, since it looks easy and it isn't that far in from the plug. It's 1/4 of the cord length. | |
| Apr 2, 2019 at 16:14 | comment | added | Nate S. | @PeterCordes, if it were modern I'd agree, but OP said it's a vintage clock/radio, which depending on how vintage exactly, may mean it's full of power-hungry tubes. An amp or so wouldn't be unreasonable. | |
| Apr 2, 2019 at 14:21 | comment | added | Baldrickk | @PeterCordes the current is negligible, until someone forms a ground connection... (yes, I know what you were saying) | |
| Apr 2, 2019 at 14:08 | comment | added | Alex Shpilkin | @Christian The plastic insulation on old cables tends to become brittle and crack on its own, and even new they were much less flexible than modern ones. But your version is more amusing =) | |
| Apr 2, 2019 at 14:07 | comment | added | Peter Cordes | It's an alarm clock / radio. The current through the cord is negligible, like under 100mA (even with an inefficient power supply, 12 Watts for the clock is probably an over-estimate). The OP says the wire is intact, just showing through the insulation, so at this point the damage won't be increasing resistance. Further damage could, yes. For your own use, with no kids around that could peel off the tape, yes tape is fine for this little damage. If this was a more power-hungry appliance, your concern about resistance would be much more justified. | |
