The NSI INDUSTRIES VM-C-36 is a voltage marker rated for 20/208V applications, designed to provide clear, durable identification on electrical conductors, panels, and equipment. Voltage markers are used by licensed electricians and electrical contractors to label live conductors and panel components with the correct operating voltage, supporting safe identification during installation, inspection, and maintenance. The VM-C-36 helps maintain compliance with NEC labeling requirements at 20/208V service points.
This voltage marker is suited for use in both residential and commercial electrical installations where 20/208V circuits require permanent, legible identification. Typical applications include panelboards, switchgear, motor control centers, and branch circuit wiring. It is installed by licensed electricians during rough-in, trim-out, or service work to ensure conductors and terminations are correctly identified before energizing.
Designed as an OEM-style voltage marker for use on 20/208V electrical conductors, panelboards, and associated electrical equipment in residential and commercial installations.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit or panel before applying markers to conductors or terminations. Markers should be applied to clean, dry surfaces to ensure adhesion and legibility over time.
