CEM DT-904 Digital RCD Tester

The DT-904 is the Basic test Equipment an Electrician cannot do without. The DT-904 is a Dual Function Test Instrument utilized to Verify electrical Wiring Connections and the Functioning of Earth leakage / Residual current detectors 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.

This ensures the Electrical installation meet safety regulation requirements.
