Gardner Bender GCM-221 Digital Clamp Meter 600V Ac 600A

Product Description

The GARDNER BENDER GCM-221 is a compact digital clamp meter designed for AC voltage and current measurement in electrical systems. It handles up to 600 volts AC and 600 amps AC, with a resistance function up to 200 ohms. The auto-ranging feature selects the correct measurement range automatically, reducing setup time on the job. The 1000-count display delivers clear readings in tight spaces. Electricians and electrical contractors use this meter for quick diagnostics, load checks, and continuity work on residential and light commercial circuits. The jaw opens to 1.25 inches, fitting standard conductor sizes found in panel and branch circuit work.

The GCM-221 is suited for use on AC electrical systems in residential, commercial, and light industrial settings. Its compact form factor makes it practical for work inside electrical panels, junction boxes, and equipment enclosures where space is limited. Electricians reach for this meter during service calls, inspections, and routine troubleshooting. The included AA battery and spare allow immediate field use straight out of the package. The 5A/250V fuse protects the meter during resistance measurements.

Installation Notes

Installation and use of this meter should be performed by a licensed electrician or qualified electrical tradesperson following applicable NEC guidelines. Always verify the circuit voltage does not exceed the 600V AC rating before taking a measurement. Do not use on DC voltage or current circuits, as this meter measures AC only. Inspect the test leads and jaw for damage before each use.
