The TEL1 is the Basic Test Equipment an Electrician cannot do without. TEL1 is a Dual Function Test Instrument utilized to Verify Electrical Wiring Connections and the Functioning of Earth Leakage / Residual Current Detectors devices by forcing the ELCB/RCD to trip.

This verifies that the protection device open the mains power supply circuit when a current higher than a certain amplitude circulate into the ground/earth wire (generally around 15mA).

This ensure the electrical installation meet safety and regulation requirements. The Wiring Check is reported on the Bright Neon Lights and the Key code is shown on the table located under the tester.

The WIRING INTEGRITY CHECKER of the TEL1 uses three Large and Bright Neon Lights to detect and display voltage conditions on and between powered electrical wires .

These neon lights will lit according to a different sequence related to the wiring conditions of the electrical system. The table located under the tester shows the wiring conditions.

The Residual Current Detector or Earth Leakage Circuit Breaker Tester injects and simulate a Ground/Earth Fault current into the Earth/Ground wire to trip the device under test. The fault current can be increased by rotating the switch to the new higher value to force the device to trip.

Nominal Voltage System: 110V-220V-230V-240Vac.
System Voltage Frequency: 50-60Hz.
Wiring Check Accuracy: Table Valid for Voltage within 5% of nominal voltage. If voltage differs from Nominal Voltage System by more than 5%, table may be incorrect.
Earth / Ground Current Simulator Accuracy: Current is set by Selected Resistors and therefore Proportional to Voltage. Resistance Accuracy is 10% Maximum.
Overall Rating: Intermittent Rated (Press TEST Shortly). DO NOT KEEP PRESSING TEST.
Resistance Rating: Current Injection System uses Resistors which are Not Continuously Rated.
Case Material: ABS.
