Switchboard Maintenance and Replacement – Tallinn & Harjumaa
The electrical distribution board is the most critical component of your home's electrical system. Outdated, overloaded, or faulty protective devices pose a serious risk of fire and electric shock. Our certified electricians offer complete switchboard maintenance, modernisation, and full replacement in Tallinn and across Harjumaa, in full compliance with Estonian electrical safety standards.
When does your switchboard need maintenance or replacement?
An old fuse-based system – older switchboards with porcelain or rewirable fuse carriers do not meet modern safety requirements and provide inadequate protection against short circuits and overloads. Replacing them with a modern circuit breaker panel is an investment in safety and convenience.
Repeatedly tripping circuit breakers indicate that the panel is overloaded, that a breaker has worn out, or that a hidden fault exists in the electrical network. Diagnosis and replacement are essential.
Missing residual current devices (RCD) – the absence of an RCD is a direct source of danger. An RCD trips within a fraction of a second and protects people from electric shock. Estonian building regulations require RCDs in wet areas and for external installations.
An old, undocumented panel – in many older buildings, electrical switchboards were installed without proper schematic drawings or documentation. This makes maintenance and fault-finding difficult and dangerous. We install all panels with full documentation and accurate schematics.
Our switchboard services include:
Full panel audit and diagnostics – using thermal imaging cameras we check for overheating connections, measure load distribution, and assess the condition of all protective devices. You receive a comprehensive report on the current state of your panel.
Circuit breaker and RCD replacement – we install devices from leading manufacturers (ABB, Schneider Electric, Hager, Legrand): miniature circuit breakers (MCB), residual current devices (RCD/RCCB), and combined protective devices (RCBO).
Load balancing – uneven load distribution across phases causes overloading and energy waste. Our specialists redistribute loads evenly across all phases.
Surge protection installation – protects valuable equipment (televisions, computers, appliances) from lightning strikes and voltage spikes.
Full switchboard replacement – we replace old panels with modern, expandable, and fully documented distribution boards. All work is certified and documented in accordance with Estonian legislation.
Maintenance contracts – regular switchboard servicing (1–2 times per year) extends equipment life, maintains safety, and prevents costly breakdowns. We offer maintenance contracts for businesses and apartment associations.
All work complies with EVS standards. Warranty provided, free quotes available.
