Hellermanntyton TCWM3 Wire Marker Book

Product Description

The HELLERMANNTYTON TCWM3 is a wire marker book designed for labeling conductors, terminals, and wiring harnesses in electrical and low-voltage installations. Wire marker books provide pre-printed adhesive or wrap-around labels that allow technicians to identify circuits quickly and accurately during installation and service. The TCWM3 is sold as a single unit and is suited for use by electricians, HVAC technicians, and low-voltage contractors who need a fast, consistent method of circuit identification on the job site.

Wire marker books are used in residential and commercial electrical panel work, control panel wiring, HVAC equipment wiring, and low-voltage system installations. They are particularly useful during rough-in and final inspection stages when circuit identification is required by code. The TCWM3 fits into standard labeling workflows where hand-written tags are not practical or acceptable.

Installation Notes

Wire marker books are typically applied by electricians and HVAC technicians as part of panel wiring, equipment wiring, or control circuit labeling. Always de-energize circuits before applying markers to live conductors. Follow applicable NEC requirements for circuit identification when labeling branch circuits and service equipment. Markers should be applied to clean, dry wire insulation for proper adhesion.
