3M 10455NA Premium Electrical Tape 0.75x350in Vinyl

Product Description

The 3M COMPANY 10455NA is a premium-grade vinyl electrical tape designed for insulation, color-coding, and splicing of electrical wiring in both indoor and outdoor applications. Built from all-weather vinyl at 8.5 MIL thickness, it delivers durable protection against moisture, abrasion, and temperature extremes. The tape is flame retardant and carries UL approval, meeting the performance expectations of licensed electricians and maintenance professionals working on low-voltage wiring systems. Each roll measures 0.75 inches wide by 350 inches long and includes an integrated cutter dispenser for clean, tool-free tear-off on the job.

This tape is suited for residential and commercial electrical work where a reliable, conformable insulating wrap is required. Common applications include wire bundling, jacket repair, terminal insulation, and phase identification on branch circuit wiring. The all-weather vinyl construction holds up in conduit, junction boxes, and exposed outdoor installations where standard-grade tapes may fail under UV exposure or temperature cycling. Electricians working to NEC compliance requirements will find the UL-listed rating relevant for inspected installations.

Key Features

• 8.5 MIL vinyl thickness for heavy-duty insulation and abrasion resistance
• All-weather construction withstands moisture, UV, and temperature extremes
• Flame retardant formulation meets safety requirements for electrical applications
• UL approved for use in inspected and code-compliant electrical installations
• Integrated cutter dispenser allows single-hand, tool-free tape dispensing
• 350-inch roll length reduces mid-job roll changes on large wiring tasks

Compatibility

Designed as a general-purpose OEM-style electrical insulating tape suitable for low-voltage wiring, splicing, and color-coding applications across residential and commercial electrical systems.

Installation Notes

Installation is typically performed by licensed electricians or qualified maintenance personnel. De-energize and lock out the circuit before applying tape to any conductor or splice. Apply with firm, overlapping passes to ensure full adhesion and void-free coverage, particularly on irregular or bundled surfaces. Follow NEC guidelines for minimum insulation requirements when using tape as the primary insulating wrap on a splice.
