Overview
The Hubbell Chance C403-2794 Digital Voltage Indicator is a field-proven tool for determining voltage presence and approximate phase relationships on energized power conductors and apparatus. Rated for 1 to 40 kV applications, this digital indicator delivers direct-reading accuracy essential for lineworkers, utility maintenance crews, and electrical field personnel who must confirm circuit de-energization or detect induced voltage before work begins.
Key Features
- Digital readout display for quick, accurate voltage detection
- 1 to 40 kV measurement range covering most distribution system voltages
- Hooked probe design allows direct contact with overhead conductors or apparatus
- Compatible with underground test points, bushings, and elbow connectors
- Compact, handheld form factor for field convenience
- Reliable Hubbell/Chance brand construction for professional utility work
