Built for industrial environments, it features a nylon toggle body and a steel, nickel-plated bridge that resists corrosion under demanding conditions. The one-piece rivetless copper alloy spring contact arm and terminal plate maintain proper contact alignment for extended service life. Large silver alloy contacts reduce erosion, and the one-piece integral grounding terminal with an 8 AWG brass screw provides a low-resistance ground path. Licensed electricians install this device in commercial and industrial wiring systems where robust, clearly marked switching components are required.\u003c\/p\u003e\u003cp\u003eThis switch is designed for heavy-duty industrial applications in both commercial and residential electrical distribution. Its back and side wiring capability accommodates feed-through installations without pigtailing. Back wire entrance points accept two wires per terminal, simplifying multi-outlet circuit runs. The color-coded base and prominent amperage marking assist in quick identification during termination. Stainless steel automatic grounding clip maintains grounding continuity between the mounting strap and metal wall box, meeting standard installation requirements in conduit and metallic box assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20 amp current rating across a 120 to 277 volt AC operating range\u003c\/li\u003e\n\u003cli\u003eSingle-pole operation with nylon toggle and thermoplastic body for impact resistance\u003c\/li\u003e\n\u003cli\u003eSteel, nickel-plated bridge provides corrosion resistance in industrial environments\u003c\/li\u003e\n\u003cli\u003eOne-piece rivetless copper alloy spring contact arm assures long-term contact alignment\u003c\/li\u003e\n\u003cli\u003eBack and side wiring with feed-through capability eliminates need for pigtailing\u003c\/li\u003e\n\u003cli\u003eStainless steel automatic grounding clip ensures continuity between strap and metal wall box\u003c\/li\u003e\n\u003cli\u003eThread-cleaning captive mounting screw and strip gauge included for accurate, secure wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation toggle switch for industrial and commercial single-pole AC switching applications rated up to 20 amps and 277 volts AC.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before beginning any wiring work. Use the built-in strip gauge to ensure consistent wire strip length for all terminal connections. Confirm the grounding clip makes solid contact with the metal wall box or mounting strap before securing the device.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120 to 277 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rating\u003c\/strong\u003e: 1 HP at 120 volts, 2 HP at 277 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Single Pole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Toggle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: Back, Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon toggle, thermoplastic body, steel nickel-plated bridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Ivory\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -40 to 75 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Industrial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL, CSA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: CN\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HUBBELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1221I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HUBBELL","offers":[{"title":"Default Title","offer_id":51283927073074,"sku":"1221I","price":15.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279185.jpg?v=1781063389","url":"https:\/\/voomisupply.com\/products\/hubbell-1221i-single-pole-toggle-switch-20a-120-277v","provider":"Voomi Supply","version":"1.0","type":"link"}
