Low Voltage (LV)

Low-voltage installations
built for capacity and safety.

LV is not “just pulling cables”. It’s circuit design, proper sizing, protection and labeling so the system performs long-term—and can be serviced safely.

What to expect from an LV installation

We don’t sell “hours”. We sell an outcome: safety, performance, clarity and a handover that flows into inspection and service.

Safe design and execution

  • logical circuits, selectivity and protection sized to real loads
  • protection against electric shock, faults and outages
  • expansion-ready approach (reserves, interfaces, capacity planning)

Cable routes and penetrations

  • trays/ladders/conduits selected for environment and mechanical loads
  • orderly routing and segregation (power vs. data/ELV)
  • service access and penetrations—no “sealed-in” shortcuts

Switchboards and labeling

  • clear distribution boards/switchboards with unambiguous circuit labels
  • tags, circuit identification and maintenance logic
  • interfaces to switchboard manufacturing and documentation

Documentation and inspection

  • handover package usable in operation (print + digital as agreed)
  • initial inspection handled by our own certified inspectors
  • follow-up service and non-conformity fixes without blame shifting

When it pays to call pros

When you don’t want outages, circuit “guessing games”, or inspection findings without clear accountability. LV should be peace of mind—not a risk.

Refurbishing old wiring

Aging aluminum wiring, improvised fixes and missing documentation are frequent fault sources. We rebuild safely and cleanly.

New technology / higher load

Machine supply, inrush currents, reserves, selectivity—if you underestimate these, production is the first to feel it.

Examples from the field

No gimmicks—just real installation types we deliver most often. Photos show our standard of workmanship.

How the cooperation works

A simple process that removes “site surprises”. In industry we schedule work so production doesn’t need to stop.

Book a time
01

Quick consultation

You tell us what you need. We clarify scope, risks and dependencies (switchboards, inspections, lightning protection).

02

Site review and execution plan

We assess the current state, loads and environment, then propose a plan that fits both operations and deadlines.

03

Clean execution

Phasing, safety, clean worksite and coordination. In industry, often also in live operation (per agreed regime).

04

Checks, testing and handover

Functional verification, labeling, documentation and inspection—handed over so maintenance never has to guess.

Trusted by industry leaders.

Long-term partnerships with top companies in industry and the public sector.

Frequently asked questions

What’s included in low-voltage power (LV), and when does it make sense to handle it as a standalone scope?

LV includes installations up to 1,000 V AC. It’s worth treating as a standalone scope for new builds, refurbishments, operational expansions, technology hookups, or when you want higher reliability (selectivity, capacity reserves and clear labeling).

Do you deliver LV power mainly for companies and industry?

Yes. Most commonly we deliver for commercial buildings, warehouses and production halls—new installations and refurbishments. We can also handle residential buildings and selected home installations depending on project scope.

Can you execute work in live operation (without long outages)?

Yes. For commercial and industrial sites we plan phasing, cutovers and outages so the operational impact stays minimal. Safety, coordination and a clear schedule are key.

How do you ensure reliability: selectivity, circuit structure and capacity reserves?

We design so a fault shuts down as little as possible. Circuit logic, protective selectivity, route sizing and reserves for future expansion are set so the system doesn’t operate ‘on the edge’.

Can you increase capacity and modify main routes when production is expanding?

Yes. We assess your current state, reserves, routes and switchboards, then propose upgrades with correct sizing, protections and interfaces—stable today and expandable tomorrow.

Do you deliver service connections and main building feeders as part of the solution?

Yes. Connections and main feeders often define what the installation can handle. We design sizing, routing and interfaces to switchboards so the whole system works as one.

Do you handle grounding, bonding and protections (RCD/SPD) as part of LV?

Yes. Earthing and bonding (MET/HOP, machines, structures) are handled system-wide. Protections (RCD/SPD) are designed based on building type, risk level and interfaces to switchboards and lightning protection.

Do you design and manufacture switchboards in-house?

Yes. We design and manufacture switchboards and can directly integrate them into LV installations. One team means one documentation set, consistent labeling and a clean handover without gaps between suppliers.

Will we receive documentation, labeling and the initial inspection?

Yes. Clear labeling and maintenance-ready documentation are standard, along with the initial inspection by our own certified inspectors. For larger projects we can also set a follow-up inspection plan and service regime.

Do you provide thermography of switchboards and routes as outage prevention?

Yes. Thermography is a practical maintenance add-on—detecting overheated connections and components under load before they fail. Outputs include thermal images, risk notes and recommended next steps.
