3M 1700C-3/4X66FT-BROWN Vinyl Electrical Tape 0.75 in X 66 Ft

Product Description

The 3M 1700C-3/4X66FT-BROWN is a general-purpose vinyl electrical tape designed for protective jacketing and wire harnessing applications. The tape measures 0.75 inches wide by 66 feet long with a 7 mil total thickness and is built on a rubber adhesive backing. It carries a 600-volt rating and is flame retardant, making it suitable for insulating and bundling conductors in low-voltage wiring work. The 1.5-inch core fits standard tape dispensers used in the field. Electrical contractors, maintenance technicians, and panel builders commonly reach for this tape on both service calls and new construction work.

This tape is rated for use across a temperature range of 32 to 176 degrees F, which covers typical indoor and protected outdoor wiring environments. The brown color supports color-coding practices used in harness assembly, multi-conductor identification, and phasing work. It ships in a 10-roll carton configuration and is available by the case at 100 rolls per case, making it practical for stocking service vans and shop inventory alike.

Compatibility

Designed as a general-purpose vinyl electrical tape suitable for protective jacketing, wire harnessing, and conductor insulation on 600-volt-rated wiring systems.

Installation Notes

This tape is installed by licensed electricians and qualified maintenance technicians. Always de-energize and lock out the circuit before applying tape to any conductor or connection. Apply with consistent tension to avoid voids or loose wraps that reduce insulation effectiveness. Follow applicable NEC requirements for insulation and conductor identification when using color-coded tape in panel or harness work.
