    Do you need to use trunking when installing a new UK plug socket and plaster?


    I have added a new double socket above an original one, and now it's time to plaster in the gap (which was used to get cables in), but do I need to trunk the wires before plaster them? I get mixed answers on this topic.

    And if so, what sort of trunking should use.

    Thank you!

    "Is the socket protected by an RCD? Is the cable deeper than 50mm in the wall? If not then yes it would need to be protected by containment.

    I’m assuming you have chased in the cable and new socket, if so and the socket is protected by an RCD then you don’t need to use trunking, a couple of cable clips would suffice.

    You could use plastic cable capping to keep the cable nice and neat before plastering."

    "You should use either capping or oval conduit due to lime in plaster eventually corroding cable.
    RCD protection is required unless cable is in conduit at a depth of 50mm."

    "You should cover the cable with capping before plastering over it. This so the cable is protected over the plaster."

    If the cable is protected by RCD and comply with the safe zones,you don t need any trunking."
