  4. 4. HOME ELECTRICAL INSTALLATIONS● Elements of control and distribution panel are:● PCS (ICP): Power Control Switch, controls thatconsumed power not exceeds the maximumcontracted power by user. It is sealed by providercompany.● AMS (IGA): Automatic Main Switch, protects aninstallation against high intensities and shortcuts.
  5. 5. HOME ELECTRICAL INSTALLATIONS● RCD (ID): Residual Current Device, is a securityswitch that disconnects all the home installationwhen there is any earth fault.
  6. 6. HOME ELECTRICAL INSTALLATIONS● MCB (PIA): Miniature Circuit Breaker, exists one byeach internal circuit, protects each circuit againstoverloads and shortcuts. It allows disconnect zonesindividually.● The number of MCBs in the control and distributionpanel depends on the metering type (with or withouttime discrimination) and the electrification level ofthe home.
