Each apartment has its own eletrical cubicle

This cubicle was originally equipped with a 500mA residual current circuit breaker calibted at 30 Amps and with a serie of dedicated fuses. (Picture beside)

In case of required modification, for example upon an apartment renovation, it is necessary to comply with the new rules. The NF C15-100 standard determines the new content of this cublice (main breaker and type & number of sub breakers) depending on the number and type of connected appliances and on the surface of the apartment.
