content: Someone posted these pics of the internals of a power strip on another forum.How are the wires connected to the busbars? Is it some kind of glue?

content: On first picture there is a spot weld indication inside. The main question is, this weld is with the cable, or between the two metal stripes?If I need to choose, I would say that is just glue on cables....

content: Very poor connection, some of the copper stains are spot welded, the rest are held in place with glue, only the spot welded strains will carry current

content: China strikes again, this time burning down our houses as part of a silent war. Some estimates already say 1 million Africans now die per year due to fake Chinese malarial drugs. All this because the West is agreeable and stupid enough to put faith in hand-shakes and trade deals without punitive measures to back them up. Please don't import their food - it will be the end of us. What I really want to know, is how far they will go till we notice the major events on the radar..

content: Nah, it's been soldered ok. They just spray paint it afterwards so the scrap metal it's made from won't rust and looks like copper.

We already got alerted that this fish is normally living in a junk water, even with high concentration of heavy metals... but hey, it is cheapNowadays is very hard to find good power strips, at least on my location....

content: Euro socket, and yes it looks like they spot welded them ( poorly) then put the hot snot to hold the pieces together so the little flakes of CCA that will invariably fall off the plated steel ( brass is expensive, so just brass plate it, she'll be all right) will still not fall out of the plastic housing.The 2 halves of the conductor strip are not spot welded together, that looks more like a formed rivet in the metal, a mechanical fastener.Amazing is that the cable conductors actually are the right number of strands, and the PE is the same number of strands, I regularly see that the PE is half the metal and twice the plastic ( guess which is cheaper) in cables.Yes the modern made stuff, even from reputable manufacturers who have an established name for quality products, is now a lot poorer, with the material being thinner, the rating being nominally the same but in real life they do not meet this. If I try drawing 16A ( the rated current in S Africa) from a modern outlet plate, using a cheap 16A rated plug, it will overheat and possibly catch fire. Outlet uses thin brass which loses spring after 5 insertion cycles, and the plug that goes in it uses a plated hollow steel pin with stamped wire terminals, not the old one which uses a brass stamping with a backing spring steel collet to ensure contact, and the plug has solid brass pins with a cut thread for the wire holding screw.
