F C E Posted September 19, 2006 Share Posted September 19, 2006 Hey All, Just found another forum site with this posted in the electrical section, What would you say to the Following Quote: Can I solder a ring main? i.e. I need to connect one 2.5mm mains cable to another in a very tight space. Is it OK for me to solder (and insulate) these cables rather than to use a screw-block? I was about to solder them when my builder told me "Jack, never solder mains cables. Mains cables get hot and the solder will mealt". I'm pretty sure this is incorrect. Solder mealts at about 190 degrees C. Something is VERY wrong if a ring main gets up to 190! Not to mention that the insulation will fail long before the solder. I'm a house owner, not an electrician although I do have electronics A-Level and I've been playing with wires since I was quite small. So: Will a ring main get hot enough to mealt solder, even under fault conditions?
