    PIR code... Intake ?

    What do you make of this, would any of you give this a code, it's the intake coming in split between a row of properties, the conductor has been joined but is exposed and has tape on it, I'm thinking to just note it on the cert and not warrant a code?

    Quick installation question.

    Hi guys, I would appreciate your opinions please. Would you think that clipping cables direct to an exposed beam directly underneath the floorboards above would be acceptable.

    Can I disguise exposed rails?

    For some reason the installer has left up to 18" of rails showing to one side of panels. If he makes fixings in the next rafter there would be a line of holes in the slate roof which could leak. Are there any black or grey trims available that could clip on the exposed rails?

    Crimping lateral mains

    Hi, Anyone here see any problems crimping 16mm lateral mains as a repair as opposed to re-running a complete new cable? I'm talking line, neautral and earth for 12 flats, 60Amp fuse. Junkies keep on nicking all the cable. Thanks Jammin
