Measuring 3 inches wide and 20 feet long with a 30 mil thickness, this tape delivers a substantial build in a single wrap, making it well suited for bundling, insulating, and protecting conductors and splices. The rubber-based adhesive provides reliable bonding across a range of surfaces encountered in field and panel work. Licensed electricians and electrical contractors will find this roll practical wherever a wide-format insulating tape is needed on the job.\u003c\/p\u003e\u003cp\u003eThis tape is intended for insulating applications in residential and commercial electrical installations. Its 3-inch width makes it an efficient choice for covering larger splices, wrapping conduit transitions, or insulating connection points that would require multiple passes with a standard 3\/4-inch roll. The 30 mil thickness adds mechanical protection where wiring is exposed to physical contact or abrasion. It is appropriate for use by licensed electricians performing panel work, service entrance work, or general wiring tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30 mil thickness provides heavy insulation buildup in fewer wraps\u003c\/li\u003e\n\u003cli\u003e3-inch width covers large splices and terminations efficiently\u003c\/li\u003e\n\u003cli\u003eRubber adhesive bonds firmly to conductor insulation and common electrical substrates\u003c\/li\u003e\n\u003cli\u003eSeries 77 formulation rated for insulating service\u003c\/li\u003e\n\u003cli\u003e20-foot roll length suitable for multiple job applications per roll\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose insulating electrical tape suitable for use in standard electrical insulating and bundling applications where a wide-format, heavy-gauge tape is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician following applicable NEC requirements. De-energize and verify circuits are at zero voltage before applying tape to any conductor or splice. Apply with consistent tension to ensure full adhesive contact and avoid air gaps at overlap edges. Do not use as a substitute for listed wire connectors or heat-shrink insulation where those methods are code-required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 20 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 30 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Material\u003c\/strong\u003e: Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Insulating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 77\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.32 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100004701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51542625976626,"sku":"7100004701","price":76.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44c47bd1f9c9f100b277b43d945bbadc.jpg?v=1785903962","url":"https:\/\/voomisupply.com\/products\/3m-7100004701-electrical-tape-3-in-20-ft-black-series-77","provider":"Voomi Supply","version":"1.0","type":"link"}
