Corroded outdoor electrical wire splice with green copper oxidation inside landscape lighting junction box.

Quick Solution Summary Corroded wire splices outdoors usually develop when moisture penetrates a connection point and reacts with exposed copper conductors. Oxygen, water, and dissolved minerals slowly oxidize the metal surface, forming green or white corrosion that increases electrical resistance. As resistance builds, current flow becomes unstable. Outdoor lights may flicker, dim, or shut off … Read more
