Material Forensics: Melted Wire Nuts

In this material forensics breakdown, we analyze a melted wire nut. This isn't just bad luck; it's a scope-of-work defense tactic failure. When wires aren't pre-twisted and the nut is spun on loosely, it creates micro-arcing. The unwritten protocol is mechanical tightness over everything. A loose neutral under load generates enough heat to melt plastic and start a wall fire.
