It follows the NEMA L7-20R configuration, featuring a 2-pole, 3-wire female contact arrangement. The self-grounding design eliminates the need for a separate grounding jumper wire by making ground contact directly through the mounting strap to a grounded metal box. Licensed electricians install this receptacle in commercial and industrial panel-fed circuits where twist-lock retention and 277V single-phase power are required. The gray color finish is standard for commercial wiring devices in this voltage class.\u003c\/p\u003e\n\u003cp\u003eThis receptacle is suited for commercial lighting circuits, industrial equipment feeds, and other applications operating on 277 volt AC single-phase power. The L7-20R NEMA locking configuration ensures positive retention of mating L7-20P plugs, making it appropriate for environments where vibration or accidental disconnection is a concern. Typical installations include warehouses, factories, and commercial facilities using 277V fluorescent or LED lighting systems fed from a 480Y\/277V distribution panel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNEMA L7-20R twist-lock configuration for secure plug retention\u003c\/li\u003e\n  \u003cli\u003eSelf-grounding design makes ground contact through mounting strap to metal box\u003c\/li\u003e\n  \u003cli\u003e20 amp, 277 volt AC rating for commercial and industrial single-phase circuits\u003c\/li\u003e\n  \u003cli\u003e2-pole, 3-wire female contact arrangement\u003c\/li\u003e\n  \u003cli\u003eGray finish standard for commercial wiring device applications\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style locking receptacle compatible with NEMA L7-20P locking plugs in 20 amp, 277 volt AC single-phase wiring systems.

De-energize the circuit at the breaker and verify absence of voltage with a meter before beginning work. Self-grounding function is only effective when the receptacle is mounted to a properly grounded metallic outlet box; verify box grounding continuity before relying on the strap ground. Do not install in wet or damp locations unless the enclosure is rated for that environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Configuration\u003c\/strong\u003e: L7-20R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 277 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Wires\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Type\u003c\/strong\u003e: Female (Receptacle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrounding\u003c\/strong\u003e: Self-grounding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HUBBELL WIRING DEVICE-KELLEMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HBL2330SR2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HUBBELL","offers":[{"title":"Default Title","offer_id":51712252969266,"sku":"HBL2330SR2","price":55.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c4ff31916c421053cf01ba91df974bc.jpg?v=1788485675","url":"https:\/\/voomisupply.com\/products\/hubbell-hbl2330sr2-l7-20r-locking-receptacle-20a-277v","provider":"Voomi Supply","version":"1.0","type":"link"}
