Description
Product Overview
The ELEGRP NEMA L14-30P locking plug is engineered for demanding power distribution tasks where reliability and safety are non‑negotiable. Constructed from a toughened nylon housing, the plug resists cracking, abrasion, and impact, while the internal copper‑brass blades ensure excellent conductivity and low resistance under load. Rated for 30 amp at both 125 V and 250 V, this four‑pole, four‑wire grounding plug meets UL standards and is suitable for a wide range of industrial and mobile applications. Its compact dimensions—2.01 × 2.01 × 3.54 inches—and lightweight design (4.55 oz) make it easy to integrate into existing power systems without adding bulk. The plug features a secure locking mechanism that engages tightly with compatible receptacles, preventing accidental disengagement caused by vibration or movement. An internal cord clamp provides a firm grip on the attached cable, ensuring a stable electrical connection that resists loosening over time. The product’s model number L1430P and its UL listing underscore its compliance with rigorous safety standards, giving users confidence in long‑term performance.
