White paper release on 8488-1

To help electrical contractors meet British Standard 8488-1, Schneider Electric has published a white paper outlining the effects of the new standard on prefabricated wiring systems and how to overcome them.

White paper release on 8488-1

The speed and ease of installation of prefabricated wiring systems has meant they are fast becoming a preferred method. To reflect this, a new standard, BS8488-1, was published that addressed the need for a regulation of the complete wiring system rather than simply the individual components.

This standard has had implications for the way prefabricated wiring systems should be constructed, so Schneider Electric has issued a white paper examining what these are and how to address them. For example, clause 3.4 states that "an installation female connector is the supply side portion of an installation coupler, which contains the receptacle contacts designed to accommodate the male connector"; basically meaning that ring circuit solutions offered by some manufacturers, which have both male and female connectors on the supply side, are now illegal.

As well as looking at the impact of the standard, the paper outlines the company's ASTA-accredited laboratory research into issues such as radial circuits compared with ring mains and over heating effects on 2.5mm PVC-insulated cable. From this, Schneider Electric has formed an argument for the use of radial circuits and encourages specifiers and engineers to look at the system's technological and economical benefits of switching from the more traditional ring main configuration.

As a consequence of this research and to meet with the new standard, Schneider Electric has developed its own prefabricated wiring system.
