The Metrel A1195 Resistor Box is an essential tool for electricians and electrical engineers who need to safely test polarity and circuit connections. Using fixed resistance values, this resistor box allows you to verify an electrical installation without energising the circuit — making it ideal for dead testing scenarios where safety is a top priority.
By simulating real circuit conditions, the Metrel A1195 allows you to accurately test the functionality of your electrical tester before working on any live systems. Please note: this resistor box is designed for dead testing only and must never be used on live circuits.
