  • Similar devices that are current operated are called residual-current devices.
  • A residual-current circuit breaker cannot remove all risk of electric shock or fire.
  • Note that the nominal value of residual current indicated above is not an absolute value.
  • Once widely used, more recent installations instead use residual current circuit breakers which instead detect leakage current directly.
  • Residual current devices require a separate neutral line for each phase and to be able to trip within a time frame before harm occurs.
  • It is also recommended to install residual-current devices for protection against electrocution.
  • A residual current device works by monitoring the active and neutral lines and tripping the active line if it notices a difference.
  • Alternatively RCBOs may be used to provide both overcurrent and residual-current protection to single circuits.
  • Non residual-current circuit protection devices are called Circuit Breakers or MCBs.
  • The main purpose of black balance is to eliminate any residual current being output from the pixel sites under conditions of complete darkness, often referred to as thermal noise.
  • In such case a residual current detector is installed to detect the current leaking to ground and interrupt the circuit.
  • Residual current detection is complementary to over-current detection.
  • Residual-current device is a generic term covering both RCCBs and RCBOs.
  • Residual current detection cannot provide protection for overload or short-circuit currents, except for the special case of a short circuit from live to ground (not live to neutral).
  • Installing a residual-current device (GFCI) on the outlet may reduce the shock risk.
  • GTO thyristors suffer from long switch off times, whereby after the forward current falls, there is a long tail time where residual current continues to flow until all remaining charge from the device is taken away.
  • The main products in the field of electrical equipment are traditional and domotics switches, plates, residual current devices, intercoms and video intercoms.
  • In the United Kingdom, a residual-current device is referred to as an RCD or an RCBO when including overcurrent protection.
  • Belgian domestic installations are required to be equipped with a 300 mA residual current device that protects all circuits.
  • Nowadays, ELCBs have been mostly replaced by residual-current devices (RCDs).
