    Rubber Grommets Cable Entry - BS7671

    I am doing a non-compliance document for college. I have to find non-compliances whilst on site. I have seen an Intruder Alarm where the PVC Flexible cable is brought through bare metal, so no grommet is fitted. Can anyone tell me what part of BS7671 this would fall under and the definition, please?

    Bit of fun, Interpret the previous reg

The idea is simple; A reg number is posted and the next poster has to give their interpretation of the reg AND what they believe the regs intent to be. From a trainee, it may be hard to truly understand why a reg is worded the way it is and...

    Band 1 cabling covered by BS7671

    Hi All Just wondering if the installion method of band 1 cabling is covered by BS7671? I'm pretty sure it isn't but just been told that alarm conduits have to be secured with metal fixings. Just need to find some evidence in the regs to support this. Cheers
