BOSECKER construction site power distributors are designed and manufactured in accordance with the manufacturer standard IEC 61439 and user standard IEC 60364. The robust sheet steel housing has been developed especially for use outdoors and is extremely stable thanks to high material thicknesses and structural elements.
Installation devices are only used from renowned manufacturers to ensure safe and stable operation. Every power distributor is wired up exclusively by professional electricians and subjected to a documented unit test.
The full range comprises connection cabinets, connection distributors, main and group distributors, distributor and terminal distributor cabinets. The portfolio includes matching standard products for various specific applications, such as containers, lighting and cranes.
For connection distributors, suitable solutions are available ex stock for rapid deployment, subject to the regional TAB requirements of the supply area in question.
Power distributors as special solutions to supply construction containers and construction site floodlights / lighting and for controlling pumps. Our standard lighting distributors are already equipped with output terminals for control and lighting. … More
Crane distributors with RCD protection switches sensitive to universal current are used to supply power to machinery and equipment with frequency converter-controlled drives, such as construction cranes, tunnel construction equipment or lifts. … More
Terminal distributors are fed via an earthed or CEE device plug and are used to distribute power to other earthed and CEE sockets. Socket distributors are compact, portable and are used to distribute power from hand-operated electrical equipment. … More
In addition to the construction site power distributors range, connection distributor cabinets are also available for the various supply territories in Austria, Luxembourg and Switzerland. ...More
Different standards and regulations apply to the manufacture of a low-voltage power distributor and the installation of a complete low-voltage system and its operation. To manufacture a power distributor, referred to in the standards as a switchgear and control gear assembly, a standardised regulation applies. A separate regulation is only in place for construction site power distributors. For this reason, we have adapted the power distributors in our construction series to the intended application.
"Low-voltage switchgear and control gear assemblies Part 1:
General definitions" (IEC 61439-1:2011)
"Low-voltage switchgear and control gear assemblies Part 4:
Particular requirements for assemblies for construction sites" (IEC 61439-4:2012)
"Low-voltage electrical installations Part 7-704: Requirements for special installations or locations - Construction sites"
"Assemblies for Construction Sites; connection cabinet 400 V; direct metering up to 100 A"
"Assemblies for Construction Sites; converter metering 100 A, 250 A and 400 A"
"Assemblies for Construction Sites; connection cabinet 400 V; converter metering 630 A"
"Assemblies for Construction Sites; connection cabinet 400 V; converter metering, internal wiring"
"Selection and operation of electrical systems and operating materials on construction and installation sites"
Important excerpt: Point 4.2.2
The following safety measures must be applied for these power circuits:
Power circuits with rated current of In ≤ AC 32 A must be operated via residual current devices (RCDs) with a rated differential current of I ∆n ≤ 30 mA,
Power circuits with rated current of In ≤ AC 32 A must be operated via residual current devices (RCDs) with a rated differential current I of ∆n ≤ 500 mA.
All Bosecker construction site power distributors are manufactured in accordance with these standards and are unit checked before shipping.
The unit check comprises the following tests:
As part of our quality management system, each construction site power distributor undergoes this unit check.
To plan a construction site power supply correctly and on budget, bear in mind the following:
