HOME ELECTRICAL INSTALLATIONS● The electrical installation begins at electricitycounters room.● The counters are devices placed by companiesthat provides electricity to measure the electricenergy consumption.
HOME ELECTRICAL INSTALLATIONS● Individual derivation line get inside eachapartment through control and distributionpanel.
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.
HOME ELECTRICAL INSTALLATIONS● RCD (ID): Residual Current Device, is a securityswitch that disconnects all the home installationwhen there is any earth fault.
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.

HOME ELECTRICAL INSTALLATIONS● Most common electric circuits at home are:● Single point light: lamp or lamps that can be turn onwith a single switch.● Commuted point light: lamp or lamps that can beturn on from two or more points.● Grounded or ungrounded electrical outlets.
