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?

    I think that this is an interesting point. (Some) Wylex boards have galvanised blanks, but painted covers. However, how do you get a line conductor flapping in the breeze? A neutral conductor could become detached and present a threat. I suspect that in reality, there is sufficient contact to trip an RCD.
