The Necessity Of Adding A Residual Current Device (rcd) To The Distribution Cabinet
Date: | Read: 1
The primary residual current device (RCD) in a circuit Powbinet is typically located after the incoming line and before the branch circuit. This arrangement allows it to detect abnormalities in the current of subsequent branch circuits and cut off the power supply in a timely manner. RCDs respond quickly to current imbalances; they activate rapidly when current flows along an unexpected path.
Furthermore, placing the primary RCD in the main distribution cabinet helps create a more efficient current monitoring structure. While end-point RCDs may not cover fault currents in some upstream circuits, adding an RCD at the front end provides monitoring over a wider area.
