Test 330b Three Phase Secondary Current

How many milliamperes is the residual current protection device RCD in the secondary distribution box

This leakage current is measured in milliamps 'mA' (1/1000 amp) and if the leakage current reaches a pre-determined level, usually 30 mA '0. 03 A' the device will operate and isolate the supply from the circuit. In addition to fault protection (protection in cases of indirect contact), residual current protective devices with rated residual currents up to 30 mA also provide “additional protection” in cases of direct contact. Fires caused by ground-fault currents can also be prevented at a very early stage. Subsequently, new types of RCD have been developed. This article. RCDs, or Residual Current Devices, are designed to monitor the electrical current flowing in a circuit and automatically disconnect the power supply if it detects an imbalance between the live and neutral conductors.
