Consumer Unit Blanking Plates

Former Community Member
Former Community Member

It is conceivable that a loose live conductor could come into contact with a metal blanking plate.  Some of the twist-on  types do not make electrical contact with the (earthed / powder-coated) case in which case they thus constitute exposed conductive parts.  This means that they should be individually earthed. But there is no means provided to do do this.  So the question is: does the use of metal CU blanking plates contravene the Wiring Regulations if fitted but not earthed?

    Qbit: 
    If a compact / miniature rcbo is used, the line and neutral are both quite close to the front panel …

    If the job is done properly, I don't see why any conductor should become detached.

    If the line conductor becomes detached, there is nothing to worry about. If the neutral becomes detached and just touches the plate and nothing else, there will probably be sufficiently good contact to activate ADS, but if not, as soon as somebody touches the floating blanking plate, the RCBO will trip.

    I think that you are worrying about a non-existent problem.
