    Swapping out a cooker switch

    Have been asked to disconnect a 40A fixed line to a cooker. The new cooker is apparently a '13A, 3 pin' one, though I'll believe that when I see it. The cable isn't being removed, so it needs terminating properly. I was thinking it could go into a new plug socket, but then the RCD for the...

    Cable Capping is NOT required and DOESN'T protect

    Hi Guys :yawn: This is my understanding about the use of capping, 1. Cable Capping is not designed to protect against nails, but to protect the cable from the plasterer's trowel on traditional plastered walls and particularly aggressive lime based plasters. Neither the steel version nor the...

    would RCD socket protect rest of circuit?

    Just had a random thought come to my head, if an RCD socket was installed onto a ring or radial circuit with other normal sockets on it, would the RCD protect them too or does the RCD only protect the load off its own socket (as i suspect).

    Hi Guys, A Metalcad CU is being installed on a TT system in a farm garage. Chances arew things will be rested up against the walls so a Metalclad CU has been chosen to give it protection. All circuits will be protected by 30mA RCD / RCBO. From research it seems a 100mA time delayed RCD will be...

    Easiest way to protect 2.5mm spur off 32amp ring.

    Found a 2.5mm spur running of a ring (no rcd, 32 amp rewireable ). The spur supplies a outhouse with a CU (10amp and 5amp mcb) Due to layout cant get take spur directly from closer to the CU, or put in a separate circuit. Simplest seems to be to put in a 13amp fcu to protect the spur, however...

    .75mm flex cables.IEC. 13 amp fuse.
