Red K-LOK 400A connectors designate Line 2 (L2) in North American 120/208V power systems and Line 1 (L1) in legacy Australian/New Zealand wiring. Under China's GB 50303 standard, red identifies Line 3. Across all regional conventions, red is consistently assigned to a live phase conductor, never neutral or ground, which makes it instantly recognizable as an energized line on any job site. At the 400A class, red connectors typically appear on primary feeder legs and main distribution taps. All K-LOK 400A red connectors share the full 400A/600V specification with brass contacts, Santoprene body, and POM retaining screw. Available in line connector, panel mount receptacle, double set screw, and threaded stud configurations.
