Introduction Issues can often arise during the replacement of a consumer unit without the condition of the existing circuits having been first assessed. A defect identified after the replacement has ...

When energised and in normal use, electronic items such as computers can cause current to flow in the circuit protective conductors (protective conductor current) which may, should the protective ...

Electrical stresses were severely introduced into power device because of the high efficiency and integration for satellite power supply system. To eliminate the reverse voltage spikes of power ...

Residual Current Device or RCD is a life-saving device designed to give protection against fatal electric shocks if you touch a live wire. It can also offer protection against electrical fires. RCD ...

Dear all, We have an electric boiler in a central London property. The boiler is over 4 years old and keeps tripping off the central heating circuit in the residual current device (RCD).

This article presents some circuit ideas using the RCD driver. Such ideas are voltage-dimming control, potentiometer dimmer, PWM to analogue dimming control, and RGBW mixer.
