Legrand has demonstrated why it is the UK’s leading cable management manufacturer by becoming the first to respond to an amendment to the 17th Edition Wiring Regulations that means the vast majority of metallic cable trunking systems are no longer suitable for use with single insulated (non-sheathed) cables.
BS7671: 2008 – Amendment No. 1: 2011 came into force for all new designs on January 1st, 2012 and Section 521.10.1 stipulates the need for trunking to deliver IPXXD or IP4X protection when used with single insulated (non-sheathed) cables – something that standard IP30 rated systems do not deliver.
Legrand’s Salamandre distribution trunking is currently the only system that meets the IP4X requirements of the 17th Edition amendment. This has been achieved through the introduction of a cover strap, which is simply connected to each coupler over the joint between the two lids, and a new range of IP4X fittings that integrate fully with existing lengths and accessories to deliver a fully compliant solution. To reinforce the success of its fast fit trunking launch last year, the new range has been designed with speed of installation as a key factor.
Legrand has backed up this timely development by launching a new CPD course. A guide to specifying and installing metallic cable trunking systems is available now and can be delivered either at Legrand’s customer training centre in Birmingham or taken directly to a client.
Nigel Leaver, lead marketing manager for Legrand’s cable management division, said: “It is important to note that the regulation changes impact on all installations that use single insulated (non-sheathed) cables, which are probably the most commonly used cables in the UK.”
