Okay so apologies for derailing this one slightly, lets get back on track.
New reg 521.10.202 suggests that all wiring systems shall be supported so that they will not be liable to premature collapse in the event of a fire.
This replaces the old requirements for escape routes only.
Does this mean an end to clipped direct with PVC clips and plastic conduit saddles ? Buckle clips or similar and metal saddles are the obvious solution here, but does anything exist as a retro fit to existing containment systems like dado and perimeter trunking to meet this requirement ?
What about plastic SWA cleats ?
