content: I wanted to re-purpose these large gauge wires that came with something I bought. I needed to put on different connectors so I first removed the heat shrink. You can see what I found. Utter incompetence was revealed. You can't trust anything is built right without inspecting what's under the covers.

content: heavy gauge is always suspect.The tools are expensive and matching the parts correctly is hard (in design and implementation). I almost never trust cheap heavy gauge things.Some engineer that crimped a single 12 gauge lug in their life said' THATS EASY TO PUT ON THE WORK LINE BRO'

content: A while ago, I bought a cheap demagnetizer. It works well but I felt the urge to have a look inside the metal case and found this...

content: @xrunner: make sure it's actually copper. Try putting a strand on a candle or stove flame, copper won't melt or deform but CCA will lose its copper coating or (with enough heat) melt.Quote from: coppercone2 on January 12, 2025, 09:10:58 pmJ-class noise suppression capacitor.

content: Quote from: Whales on January 12, 2025, 10:35:45 pmI often wondered about that, if you can do a PCB plane capacitor to act as a earth ground cap.I am not certain of it, but I was thinking, especially if there is ALOT of layers on a PCB, it might be possible to make some kinda capacitor like that.That might be considered a class K noise suppression capacitor

content: Quote from: Whales on January 12, 2025, 10:35:45 pmAlso put a magnet up to it in case it's CCS. For heavy-gauge, i.e. high-current stuff that's even more dangerous than CCA.

content: Quote from: coppercone2 on January 14, 2025, 08:29:48 amSure its lazy work and not NASA grade, but without a current spec from OP, we don't know if its an actual problem or not. They probably got what they paid for.Its the same deal as people whining about non-soldered alligator leads that they paid 50c for (not OP in this case).
