WHITE PAPER Residual current devices (RCDs) Protection
RCDs can provide protection for people against fatal electric shocks due to earth leakage and can also provide some protection against fire in installations.
Residual Current Devices | part of Electrical
This chapter provides basic information on how a residual current device (RCD) works, what level of protection such devices offer, and where they should be used.
residual
Medicine remaining in an organ or part following normal discharge or expulsion: residual air. Geology remaining after the soluble elements have been dissolved: residual soil.
Residual Current Protective Devices
If a residual current protective device for other protection tasks (fault protection, fire protection) is connected upstream of an RCD for additional protection (rated residual current ≤ 30 mA), this second

RD3 and RCQ020
The measurement of leakage current provides an attenuation of high-frequency components, which are especially due to the presence of inverters in the circuit and are the main cause of unwanted tripping
Field testing instructions and application guide
The tested current level should be chosen above the pickup level plus the tolerance to make sure the current is not causing a pickup/dropout/pickup condition. This condition can cause longer trip times.
INSPECTION AND TESTING OF ELECTRICAL
An RCD is a protective device used to automatically disconnect the electrical supply when an imbalance is detected between live conductors. In the case of a single-phase circuit, the device monitors the
