Construction site power distribution board
Testing of construction site power distribution boards according to DGUV Regulation 3

Electricity is essential on every construction site – as is the security of the power supply.
With our professional testing of construction site power distribution boards after DGUV Regulation 3, DIN VDE 0100-600 and 0105-100 We ensure that your mobile distribution systems function safely and in compliance with standards at all times.
What is a construction site power distribution board?
A construction site power distribution unit is a mobile electrical unit for distributing energy on temporary construction sites.
Typical components:
Heavy current connections (CEE 16A / 32A / 63A)
Residual current circuit breakers & circuit breakers
Feed-in points & sockets
Meter & control modules
Due to the changing environments and high loads, they are subject to particularly strict testing requirements.
Why do construction site power distribution boards need to be checked regularly?
Protection against Electric shocks & short circuits on construction sites
Avoidance of Work accidents & construction stoppages
Fulfillment of legal operator obligations
Recognition for inspection authorities and insurance companies through inspection sticker
Liability insurance for building owners and contractors
