French Electrical Systems

Electricity SupplyWiring MethodsConsumer UnitsEarthing / Bonding PrinciplesElectric Heating & Water HeatingInstallation RegulationsThe standard domestic electricity supply in France is single phase 230 volts, 50Hz. It is also common to find a 3–phase 380v distributed supply in larger properties. The electricity supply authority EDF (Electricite de France) will provide a meter, fuses and a main current operated circuit breaker (disjoncteur différentiel). They are the property of EDF and are security sealed to avoid tampering, for which there is a fine. The consumer connection can only be to the outgoing terminals of the disjoucteur différentielwhich is not sealed and available to the consumer. The EDF (disjoncteur différentiel) is rated to suit your tariff and has a sensitivity of 500ma or in some cases 650ma. This sensitivity level is not suitable for the protection of people and a second device with a sensitivity of 30 ma must be installed in the consumer unit to provide earth fault protection. The function of the EDF device is to protect you from faults that might occur both inside and external to your proper...Get price
