Construction of current protections

The construction of current protection is a key element for the safety of any electrical installation. Our team designs, supplies and installs solutions for protection against overload, short circuit, leakage current and overvoltage. We work according to established standards and provide reliable and long-lasting protection for home, office, commercial premises and production premises.

What are current protections

Current protections are devices and configurations that limit the risks of fire, equipment damage and life-threatening situations. They are combined in the electrical panel to cover all critical scenarios.

• MCB circuit breakers - protect against overload and short circuit, are selected according to curves B, C or D according to the nature of the consumers.
• RCCB residual current protections - detect leakage current and protect against electric shock and hidden fires. Suitable ratings 30 mA for personal protection and 100-300 mA for fire protection.
• Combined RCBO protection - combines MCB and RCCB in one device for personal protection of each circuit.
• Surge protection SPD - limits impulse and switching overvoltages caused by thunderstorms and network disturbances.
• Additional solutions - protection against arc faults AFDD, quality grounding and potential equalization.

Correct sizing, selectivity and coordination of time-current curves ensure reliable operation of the entire system and quick localization of problems in individual circuits.

Who is the service for and signs that you need it

• Owners of new homes or during complete renovation of the installation.
• Business facilities with sensitive equipment, restaurants, shops, offices, workshops.
• Buildings with photovoltaics, electric vehicle chargers, boilers, air conditioners and other powerful consumers.

Signs of the need for renovation

• Frequent tripping of fuses or flickering of lighting.
• Warm contacts or a burning smell around the switchboard.
• Outdated switchboards and lack of residual current protection.
• Adding new powerful appliances and expanding the installation.

In the event of such symptoms, we recommend a professional inspection and tests. For a comprehensive solution, you can also consider our electrical services, tailored to the needs of home and business.

Our work process

1. Inspection and measurements - analysis of the switchboard, wires, grounding system and current loads with professional equipment.
2. Design - selection of circuits and equipment according to BDS EN 60364, 60898, 61008, 61009, 61643, 62305 and the requirements of the network operator.
3. Selection of devices - we use components from proven manufacturers, ensuring compatibility and selectivity.
4. Mounting and labeling - clean and precise installation in the switchboard, arrangement of wires, clear marking of circuits.
5. Tests and adjustment - functional tests with measurement of tripping currents and times, test of the Test button for RCCB.
6. Documentation and instructions - measurement protocols and a short guide to safe operation.

If you are planning a wider range of activities, see also the related electrical services to combine several stages into one optimized offer.

Advantages of choosing us

• Safety and compliance - solutions according to current standards, correct selectivity and full traceability of components.
• Quality of execution - professional installation, order in the switchboard and reliable operation of installation.
• Transparent offers - clear prices and deadlines, no hidden costs.
• Warranty and maintenance - labor and equipment warranty, option for periodic maintenance.
• Minimal interruptions - planning of work with minimal power outages.

For complex sites, we can combine the service with other electrician services, which saves time and optimizes the budget.

Prices and deadlines

The price depends on the number and type of protections, the condition of the switchboard, the need for new lines, grounding and SPD. After inspection, we prepare an accurate offer with a detailed scope and deadline for implementation. We offer flexible planning so that we do not interrupt the workflow at your site.
