SwampNut Posted February 23, 2022 Posted February 23, 2022 When is it dangerous to use? This cord was used outdoors in a wet environment (marine, boat shore power). The female end apparently had water come in. I cut it off and it was blacker than a whore's heart, but not flaky. I cut off three feet and it's starting to look cleaner. The other end is perfect. Should I keep cutting? Any danger here? I wired it up with an L6-30P and N6-50R for a welder adapter and extension. The welder is rated at 30a but came with a 50a plug. My garages are all L6-30R.

XXitanium Posted February 24, 2022 Posted February 24, 2022 I'd give it a shot of this to clean the bare ends and make sure you have good contact on your screw terminals. Are those #6s? https://www.corrosionx.com/products/corrosionx Quote
SwampNut Posted February 24, 2022 Author Posted February 24, 2022 10 gauge, since it's only 30 amps. I have a lot of CorrosionX, I haven't seen it clean anything. It would protect it from moisture. It's incredibly great at that part. After the photo I cleaned the conductors a bit and got them really tight. That 6-50 recep lets you really tighten them well. 1 Quote
Biometrix Posted February 25, 2022 Posted February 25, 2022 Its dangerous when the copper is green or white, powdery and falls apart and/or when the insulation cracks and falls off in pieces. I would have had no hesitation just using those stripped ends as-is for an extension cord but that's just me. Maybe if they were blacker I would have shined them up a bit with some emery cloth but otherwise wouldn't have fucked around with it. Quote
SwampNut Posted February 26, 2022 Author Posted February 26, 2022 Useful info. I did clean it lightly with sandpaper before putting the plug together. 1 Quote
superhawk996 Posted March 1, 2022 Posted March 1, 2022 My only fear would be resistance, and the things that can manifest from that, at the connection. I might separate the strands and shine them all up if the blackening wasn't just on the surface. 1 Quote
