## Summary description

FF WNC-1 is a single-phase voltage indicator designed to detect presence or absence of phase on electrical networks. The compact panel-mount device provides clear indication of live voltage for maintenance, troubleshooting and safety checks. Suitable for distribution boards, control panels and industrial equipment where quick verification of supply voltage is required.

## Long description

FF WNC-1 single-phase voltage indicator is a compact panel-mount phase presence detector for quick verification of live voltage in single-phase electrical networks. The device is intended to provide a clear visual indication of whether a phase conductor is live or de-energised, helping technicians perform maintenance, troubleshooting and safety checks on distribution boards, control panels and industrial equipment.
Advantages
The design of this panel mount voltage indicator prioritises compactness and straightforward installation in cut-outs of control panels and distribution boards. It delivers an immediate visual signal of phase presence without requiring complex setup or large mounting space. The unit is suitable for repetitive on-site checks, reducing time spent on manual testing and improving workflow efficiency during routine inspections.
Suitable for
Quick verification of supply voltage in distribution boards
Phase presence checks during maintenance and troubleshooting
Monitoring of single-phase circuits in control panels
Use in industrial equipment panels for safety confirmation
Key specifications
Single-phase voltage detection
Panel-mount enclosure for standard cut-out sizes
Visual indication of live phase (indicator lamp/LED)
Compact dimensions suitable for crowded control panels
Designed for use on low- and medium-voltage single-phase supplies (as applicable to model)
How to use
Install the indicator in a compatible panel cut-out and secure it according to the panel manufacturer’s guidance. Connect the device to the phase conductor and neutral or to the phase and earth as required by the installation instructions. Once connected, the indicator provides a clear visual signal when the phase is live. Use the device to quickly confirm presence or absence of phase before performing work on the electrical system. Follow electrical safety practices and de-energise circuits when necessary for safe handling.
Usage recommendations
Use the FF WNC-1 phase presence detector as a preliminary check for live voltage and not as a substitute for detailed testing with certified measuring instruments. Ensure proper wiring and mounting, and periodically inspect the indicator for damage or wear to maintain reliable operation.
