The Miniature Circuit Breaker or MCB, is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. | ||||||||||

The Residual Current Device (RCD) also known as a Residual Current Breaker (RCB) or Residual Current Circuit Breaker (RCCB)
RCDs trip an electrical circuit and disconnect the load points in 30m sec. RCD devices are very effective for electric shock protection. In a typical modern Consumer Unit there will be 2 RCD's each protecting the circuits in one half of the house. |

The RCBO is a clever combination of MCB & RCD. It has the advantages of both breakers and it avoids the issue of half the house tripping out when an appliance has a fault. | ||||||||||
| Smart electronic equipment like computers, TV's and even washing machines can be sensitive to spikes in electricity supply. So, a surge protective device (SPD) which is designed to protect electrical systems and equipment from surge events is now a standard requirement in any fuse box. |  |

Finally, The Arc Fault Detection Device. AFDDs are protective devices installed in consumer units to provide protection from arc faults. They use microprocessor technology to analyze the waveform of electricity being used. They detect unusual signatures which would signify an arc on the circuit. AFDDs cut off power to affected circuitry to prevent fires. They are far more sensitive to arcs than conventional circuit protective devices but are not yet a legal requirement (2021) The decision to install should be based on a comparison between installation cost @ approx £115 (2021) and relative risk factors. | ||||||||||
