Megger DCM305E Earth Leakage Clampmeter

Brand: Megger
Model: DCM305E

designed to check earth leakage currents; however the upper range enables.

Product Information



A typical application for the DCM305E would be a measurement of earth leakage current in a circuit where the RCD keeps tripping out unexpectedly.
The measured result will quickly identify whether the earth leakage current present is excessive causing the RCD to trip or if the RCD itself is very sensitive / faulty. Earth leakage can be the result various
undetected faults in the installation or a faulty appliance.
Cable insulation deterioration, cable damage or the ingress of moisture into areas where exposed terminals are present may give rise to earth leakage current.
