If a power control breaker is single-pole type: it trips the phase conductor it trips the neutral conductor it trips the protection conductor (PE) it is compulsory that every power control breaker is multi-pole type, that is, it will trip both phase and neutral conductors.
Conductor cables need to be easily indentifiable. In this respect: the neutral conductor will be light blue coloured the protection conductor (PE) will be identifiel with blue colour phase conductors will be identified with either brown, black or yellow-green colour a and c are correct.
The REBT enforces the installation of at least: a General Circuit Breaker, multi-pole type, with manual resetting, featuring overload and overcurrent protection functions, and a minimal rated current of 25 A, dependent on the power control breaker and replaceable by it a General Circuit Breaker, multi-pole type, with manual resetting, featuring overload and overcurrent protection functions and rated current of at least 25 A a multi-pole Circuite Breaker with manual resetting, featuring overload and overcurrent protection functions and rated current of at least 25 A None.
High electrification level: Is proposed as the minimum system Is considered in homes where no significant number of electric home appliances, no electric heating ora ir-conditioning systems are foreseen Is envisaged in homes with over160m2 useful area None.
The power control breaker is: A device for ensuring that power actually consumed by any consumer doesn't exceed the contracted power A device exclusively intended for protection A device for protecting individuals A device for measuring contracted power and protecting the home installation.
Those Miniature Circuit Breakers (MCB) utilised in the different circuits of a domestic installation will feature the following minimum rated current: C1 and C5 10A, C2 and C4 20A and C3 25A 10Hz C1 10A, C2 and C5 16A, C3 25A and C4 20A None.
In basic-electrification-level homes, the installation: Will have two, four or five circuits Will consist of at least five circuits Can have up to 12 circuits Will not necessarily include a residual current device, as it is enough to use a power control breaker.
Conductors' cross-section will be determined by the type of circuit they belong to; thus: C2 conductors have 1,5mm2 cross-section C2 conductors have 2,5mm2 cross-section C2 conductors' cross-section is 4 mm2 because the microwave oven could be plugged None.
The circuit C4 for washing machine, dishwasher and electric water-heater: May reature 16A-rated current Schuko-type socket-outlets, together with 16A-rated current fuses, 2,5mm2 cross-section conductors and a miniature circuit (MCB) of 10A May reature 16A-rated current Schuko-type socket-outlets, together with 16A-rated current fuses, 2,5mm2 cross-section conductors and no 20A miniature circuit breaker (MCB), as it not needed Will typical include a 20A rated current MCB for protecting all the three elements, its conductor cables will have 4 mm2 cross section and its socket-outlets will have rated current of 20A Can be accomplished by using three independent 10A MCBs, 2,5mm2 cross-section conductors and 16A socket-outlets.
The power tiers scheduled for single-phase suppliers are: 5,750 W and 7,360 W for basic electrification level and 9,220 W, 11,500 W and 14,490 W for high electrification level 5,500 W and 7,360 W for basic electrification level and 9,220 W, 11,500 W and 14,490 W for high electrification level 5,750 W and 7,360 W for basic electrification level and 11,500 W and 14,490 W for high electrification level None.
Accordint to the REBT the following devices are required in any residential electrical installation: Overvoltage protection devices, compulsorily, in compliance with ITC-BT-19 Overvoltage protection devices, compulsorily, in compliance with ITC-BT-23 Miniature Circuit Breakers (MCB), with multi-pole tripping and manual reset, featuring overcurrent and overvoltage protection functions, for every circuit of the residential installation None.
