So I have a few extension leads all are 13A rated but the cable length is too short just 1 metre. It would be cheaper for me to rewire them than buying new extension leads.
I bought a reel of the correct cable rated for 13A and have rewired one. However just have a query in regards to the wiring itself at the plug end.
In regards to the wires in the plug end they were previously "crimped" with just a small piece of metal (the wire wasn't left bare) if that's the right term. I didn't want to leave the wire bare either and to ensure there is a good connection, so I soldered the wire ends and then was able to nicely secure them with the screw.
However I am now wondering whether there is any safety hazard to soldering the end of the wires like that at the plug end? In terms of potential heat leading the solder to melt?
May be a silly question but it just cropped up in my mind so better to ask.
After reading and considering all replies, unfortunately I was unable to find small enough ferrules in standard stores even electrical ones, not sure whether that's mainly a US thing but it doesn't seem to be common in UK? They only had wire connector types but nothing as small to be used for the entry point holes for the wire on the plug. Sure could order online on eBay/Amazon but would be unsure of the quality.
So I left them bare rather than tinned with solder as seems like the safest alternative. Strands were secured properly. There won't be any pulling on the cable anyway as it is left stationary behind a desk.
Just to add the photo is a generic plug from Google. I done a much better job with the wire lengths (or so I hope!), as the question occurred to me after I had already soldered and been using the plug for a day or two.
