1. Why is a robust distribution board the cornerstone of job-site safety?
Every electrical contractor knows that makeshift power splitting quickly leads to downtime, damaged tools and—worse—accidents. Mud, dust and shifting weather all demand a reliable power source that can withstand overloads and harsh site conditions. The Doktorvolt TGD-S/FI 32 A / 16 A construction-site distribution board was engineered precisely for these realities: it delivers stable power, safeguards people and equipment, and meets the strictest international standards.

2. Key specifications at a glance

  • 4 × 230 V / 16 A SCHUKO outlets (IP54)

  • 1 × CEE 400 V / 16 A outlet (IP44, VDE)

  • 1 × CEE 400 V / 32 A outlet (IP44, VDE)

  • Circuit-breakers: 2 × C16 (1-pole), 1 × C16 (3-pole), 1 × C32 (3-pole) – each rated 10 kA, VDE-certified

  • Residual-current device (RCD): 40 A, 30 mA, type A, 4-pole, 10 kA, VDE

  • Distribution board rating: 40 A

  • Enclosure protection: IP65 (housing) / IP44 (outlets)

  • Dimensions: 355 × 255 × 125 mm

  • Material: rugged plastic, grey front / black rear

This configuration lets you power small hand tools, work-site lighting, and high-demand machinery simultaneously—without overloading the supply lines.

3. Built for the harshest conditions

  • Dust & splash protection (IP65/IP44). A sealed lid and correctly sized cable glands keep moisture and particles larger than 1 mm away from the switchgear.

  • Compact, lightweight polycarbonate body. Won’t corrode or crack, and maintains mechanical strength even at low temperatures.

  • Ergonomic carry handles let you move the unit easily between work zones.

In practice, the board can sit directly on sandy ground, and sudden rain showers won’t trigger shutdowns or short-circuits.

4. Wide range of outlets — total power flexibility

4.1. Single-phase SCHUKO 230 V

Ideal for hand tools, chargers, LED work lights and test equipment. Each outlet is protected by a C16 1-pole 10 kA breaker, preventing nuisance trips on motor start-up while reliably disconnecting under fault conditions.

4.2. Three-phase CEE 400 V

  • 16 A / 5-pin – perfect for small mixers, heaters and compressors.

  • 32 A / 5-pin – handles heavier gear such as circular saws, hoists or plastering pumps.

Each CEE socket includes a built-in mechanical interlock that prevents the plug from being pulled under load.

5. VDE-certified protection — what does it mean on site?
The German VDE (Verband der Elektrotechnik) is one of Europe’s toughest certifying bodies. Components in the Doktorvolt board that carry the VDE mark guarantee:

  • Verified breaking capacity – 10 kA, confirmed by independent lab tests.

  • Stable tripping curves across the full operating-temperature range.

  • Low contact resistance, minimising power losses and heat build-up.

  • Age-resistant insulation materials, essential in damp site conditions.

Working together, the miniature circuit-breakers and the 30 mA RCD protect users both from short-circuits and from dangerous leakage currents above 30 mA that can cause electric shock.

6. H07V-K class internal wiring — the detail that drives reliability

The board is factory-wired with flexible H07V-K conductors (class 5 stranding) in cross-sections from 2.5 to 6 mm²:

  • Protective conductors: yellow-green, 2.5 / 4 mm²

  • Neutral conductors: blue, 2.5 / 4 / 6 mm²

  • Phase conductors: black, 2.5 / 4 mm²

Fine-strand copper makes servicing easier and cuts the risk of core breakage under vibration. Every end is crimped with ferrules, enlarging the contact area and preventing terminal screws from loosening over time.

7. Compliance with standards — your guarantee of quality and hassle-free sign-off

  • IEC 61439 – design and testing for low-voltage switchgear assemblies

  • CE mark – meets the Low-Voltage and EMC Directives

  • ISO 9001 : 2015 – certified quality-management system in the Doktorvolt factory

  • TÜV SÜD – independent auditing of the production process

For an investor this means fewer formalities during site hand-over and the certainty that neither the safety inspector nor the insurer will question the equipment.

8. Typical applications

Sector / Task Example loads
Building construction concrete mixers, plate compactors, tower lights
Road works floor saws, pneumatic hammers, message boards
Outdoor events LED stage lighting, PA systems, chillers
Agriculture grain dryers, powered silos, heat lamps
Light industry packing lines, small injection moulders, piston compressors

Thanks to its universal outlet mix, the board is ideal wherever fast, safe three- and single-phase power is required.

9. Best installation practice

  1. Location: set the board on stable ground away from flood zones.

  2. UV protection: the enclosure is UV-resistant, but prolonged sun shortens gasket life—fit a canopy if possible.

  3. RCD test: press the TEST button once a month.

  4. Documentation: record test and insulation-resistance dates in the site log—makes final sign-off easier.

  5. Torque checks: each time the board is relocated, verify terminal tightness with a torque wrench.

10. Summary — an investment in safety and efficiency

The Doktorvolt TGD-S/FI 32 A / 16 A board combines a rugged construction-site housing with precision VDE-certified protection devices. It offers flexible power options, is easy to move, and—most importantly—safeguards people and equipment from electrical faults. For site managers that means fewer stoppages and penalties, for installers effortless setup, and for end users the confidence that power is supplied safely and in compliance with all standards.
