Black K-LOK 400A connectors serve as the Line 1 (L1) phase identifier in North American 120/208V systems, the most common voltage configuration for entertainment and event power. Under IEC 60446 (Europe, UK, modern Australia), black identifies Line 2 (L2). In legacy Australian/New Zealand wiring, black marks the neutral conductor. Because black plays a role in every major regional wiring standard, it is typically the highest-volume color in any cam-type connector inventory. All K-LOK 400A black connectors carry the full 400A/600V specification, high-conductivity brass contacts, Santoprene body rated to 105°C, and POM retaining screw. Available in line connector, panel mount receptacle, double set screw panel receptacle, and threaded stud panel receptacle configurations.
