Mechanical interlock enclosures prevent two power sources from being connected simultaneously, protecting equipment and personnel from back-feed hazards. This unit is sold individually and is suited for installation by licensed electricians working on transfer switch assemblies, generator connection points, or similar power-switching applications where physical interlock control is required by code or design specification.\u003c\/p\u003e\n\u003cp\u003eThe 420MI12W is appropriate for commercial and industrial electrical installations where a mechanical interlock is needed to enforce safe switching between two power sources. Typical applications include generator interlock systems and manual transfer arrangements in panel or enclosure assemblies. It is intended for use by qualified electricians familiar with NEC requirements governing transfer equipment and overcurrent protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-pole, 4-wire mechanical interlock configuration for multi-phase applications\u003c\/li\u003e\n  \u003cli\u003ePrevents simultaneous engagement of two power sources, reducing back-feed risk\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for straightforward procurement and replacement\u003c\/li\u003e\n  \u003cli\u003eHardware accessory classification suitable for panel and enclosure integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style mechanical interlock enclosure accessory for 3-pole, 4-wire electrical switching assemblies.

De-energize all circuits at the main disconnect before beginning installation or service on the interlock enclosure. Verify that all conductors are properly rated for the intended load and that the interlock mechanism operates freely before restoring power. Do not bypass or modify the interlock mechanism, as doing so defeats its safety function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 3-Pole, 4-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\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: LEVITON TELCOM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 420MI12W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEVITON","offers":[{"title":"Default Title","offer_id":51563552637234,"sku":"420MI12W","price":2590.27,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/leviton-telcom-420mi12w-mechanical-interlock-enclosure","provider":"Voomi Supply","version":"1.0","type":"link"}
