Leviton Telcom 1K277-8W 277V 800A Single Pole Meter

Product Description

The LEVITON TELCOM 1K277-8W is a single-pole, 2-wire electrical meter rated for 277 volts and 800 amps. This unit is designed to measure electrical consumption in commercial and industrial power distribution applications. The 1K277-8W is a hardware accessory sold individually and is typically installed by licensed electricians working on metering assemblies, tenant submetering systems, or branch-circuit monitoring panels. Its 277-volt rating aligns with standard single-phase lighting circuits commonly found in commercial buildings fed from 480-volt wye distribution systems.

This meter is suited for commercial and light-industrial installations where accurate energy monitoring at 277 volts is required. Typical applications include submetering in multi-tenant buildings, monitoring individual circuits in commercial facilities, and energy management installations. The 800-amp rating accommodates high-load branch circuits and feeder-level monitoring scenarios. It is sold as a single unit and is intended for use by qualified electrical contractors familiar with metering equipment and local electrical codes.
