The electricity distribution and metering cabinet (FDCP) is an integrated part of the electricity supply installation, at 400 V rated voltage between phases, in apartment buildings, commercial, socio-cultural and administrative buildings.

Functions:

• Connection of the energy installation of the apartment buildings consumers or city buildings to the supplier’s energy installation;
• The energy supply can be ensured through one group of fuses, 2 groups of fuses or an automated circuit breaker according to the beneficiary’s demands;
• Measurement of the active energy used by each consumer and the possibility of reading the meter independently of the consumer’s presence at the measuring time;
• Protection against overload, short-circuit and residual differential currents for each consumer’s main energy supply;

• Protection against industrial frequency over-voltages occurred at each consumer, through the neutral’s accidental interruption;
• Protection against electrocution through direct contact with the live circuitry and devices;
• Protection against energy thefts and electrical equipment damages determined by the action of an ill-intended, unknowing or unauthorized person;
• Creating possibilities to limit the load peaks and reduce the technological losses;
• Protection of the consumer against industrial frequency over-voltages.

Components:

• The metallic box made of sheet metal powder coated in electrostatic field, coated accordingly to the operating conditions, respectively indoor or outdoor;
• Racking for the installment of the electrical devices;
• Meters for measuring the energy consumption;
• Single phase consumer’s mains made with: LF fuses or automated circuit breakers with over-voltage and differential protection.

The box contains 3 compartments:

• Compartment for fuses;
• Compartment for connection, protection and signaling devices;
• Compartments for meters.
