Safer by design – Hager launches prefabricated electrical distribution system
Hager has launched a fully pluggable electrical distribution system, from the distribution board to luminaires, that significantly reduces installation time and ensures full compliance with the wiring regulations.
Hager has launched a fully pluggable electrical distribution system, from the distribution board to luminaires, that significantly reduces installation time and ensures full compliance with the wiring regulations.
Klik.system consists of a number of distribution products linked by prefabricated wiring sections, which simply plug together. To ensure that the final installation complies with all of the relevant standards and regulations, Hager has also developed a bespoke software package. This produces a fully calculated design, which includes drawings, electrical calculations, test information and delivery schedules.
Says Steve York, Product Manager for Klik.system: “Some prefabricated wiring systems have been associated with serious safety issues. Areas of concern include: reversed polarity, under rated couplers and incorrectly sized wiring sections.”
In response to these safety needs, BSI has developed and then further amended the standard BS8488:2009+A1:2010 to ensure that safety requirements are met and that systems are tested.
By designing and supplying the entire system from the pre-wired pluggable distribution boards, through the lighting installation system right down to the wiring accessories, Hager can guarantee that all of the elements in the circuit are compatible.
A complete system would start with a factory assembled, pluggable distribution board that is prewired to multipole connectors. This takes individual circuits to specified areas of the building via a home run cable where it connects to an Area Distribution Box (ADB). This then supplies lighting marshalling boxes and tee pieces which in turn supplies the luminaires and switching devices.
For lighting control, specifiers can choose from a basic manual switching system, a standard automatic system using occupancy sensors and photocells or a digital system. The latter can take into account available daylight as well as artificial light to save energy as recommended by Part L.
Prewired occupancy sensors simply plug into the lighting marshalling boxes or tee pieces to provide control to the circuit. Switch drops are also pluggable so there is no need for hard-wired connections in the ceiling void.
Says York: "Prefabricated wiring systems can save up to 50 percent of time on site, but in the past there have been problems. Because we supply the complete system the specifier only needs to contact ourselves and the lighting manufacturer rather than multiple suppliers."
"In addition Hager can stage deliveries so there is no need for onsite storage and by providing a full design we reduce the risk of an incorrect installation."
