Industrial Locking Plug

The LORDWORLD NEMA L15-30P is a 30 amp 250 volt industrial grade AC power plug designed for secure twist-lock connections. It features a 3-pole 4-wire grounding configuration and operates at 60 hertz. The plug is UL and cUL listed for safety compliance.

Cord Compatibility Limits

This plug accepts a maximum cord size of 10 AWG for back wiring termination. It replaces standard straight-blade connectors where vibration or accidental disconnection is a concern. The upgrade is worth it when equipment demands a locking mechanism that prevents power loss under load.

Sustained Load Construction

The housing uses nylon and PBT materials while the terminals are brass for reliable conductivity. These materials support continuous industrial operation at the rated 30 amp capacity. The locking design maintains a stable connection during extended high-draw periods without loosening.
