Description
Product Overview
The SPERRY VD7504GFI is a dual‑function tester that merges a non‑contact voltage detector with a GFCI outlet tester. Housed in a high‑impact polycarbonate shell with soft over‑molded rubber grips, the triangular tool measures 8.4 x 3.7 x 0.6 inches and weighs just 3.36 ounces. It operates on a single LR44 battery (included) delivering up to 50 hours of continuous use. Certified to OSHA NRTL standards, it detects AC voltages from 50 to 600 V and provides both audible beeps and 360° LED illumination for safe, hands‑free operation.
Usage
Designed for professional electricians, contractors, and DIY homeowners, this combo tester simplifies routine inspections. Use the non‑contact end to quickly verify the presence of live wires behind walls, panels, or outlets without touching conductors. Flip to the GFCI side to confirm proper wiring, ground, and polarity of receptacles in residential or commercial settings. Its compact size fits easily into tool belts, making it ideal for on‑site troubleshooting, new construction, or routine maintenance.
