Legrand says it has become 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 1 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 said to be the only system that currently 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.
