WARNINGS
The Southwire 41151S Compact Voltage and GFCI Tester is a
simple and safe way to measure voltage, test for live circuits, and
test the functionality of Ground Fault Circuit Interrupter (GFCI)
circuits. This pocket tester tests AC voltage up to 480V and DC
voltage up to 110V. It’s small enough to comfortably fit in your
pocket as the test probes can be stored on the back of the tester
where they won’t catch on clothing. The 41151S is fully tested and
UL listed and with proper use, will provide many years of reliable
service.
Warnings
Comply with all safety codes. Use approved personal protective
equipment when working near live electrical circuits - particularly
