    CU change. How many RCD's?

    Hi people, I have a nice little consumer unit change to do in a couple of days. Quite a nice little job if you ask me but the funny thing is, it's in a flat and there are only three circuits. Lights, ring and cooker. What are your views on the type of CU I should put in? My thoughts are to use...

    Does a external flood light need to be on an RCD ?

    Does a external flood light need to be on an RCD, i was going to spur off a socket in the bedroom, if the fuse board doesnt have any rcd, should an rcd fuse spur be used? or can a normal switch spur be used? Thanks,

    Clarification on addition/alteration to ring protected by BS3036 fuse

    Had a look at a job today which involves some additional sockets to the ring and a FCU. As it's protected by a 3036 I was looking at providing an RCD in separate enclosure adjacent to the existing metal clad CU. Also the DNO/metering co have been in recently and installed a new meter and 100A...

    Hi, I am mounting a socket on the external wall for use in the garden. I am spurring off an existing ring in the kitchen, drilling the wall to thread through the 2.5 mm T&E cable for the socket.

    Max Zs readings where circuits are protected by 30ma RCD's

    I have noticed, a lot of max Zs readings on test certs (Where RCD's are applicable) are being blanket recorded at 1667 ohms. On a personnel note I consider this to be poor practice, and prefer to see max Z's taken from tables 41.2 41.3 and 41.4 of chapter 41 of the good old guide. My reasons are...

    Spur off a 3036 protected circuit?

    I've been asked to add a spur (or possibly extend the ring) on a BS 3036 protected circuit. Dead basic job, just needs an extra socket in a bedroom. From my understanding, this can be put down as a Minor Works, but all sockets now have to be RCD protected to comply with the 17th, so if I'm...

    Cable within domestic garage

    Can any one help me, does the cable fitted above the surface of a domestic garage wall need to be protected by conduit or will being clipped to the walls suffice? Cable will be RCD protected. Assessment evidence so it has to be correct. Thank you.

    Extending/adding concealed cables?

    Evening I know the regs say that cables buried less than 50mm in a wall or partition need to be mechanically, or rcd protected, but if these circuits arent rcd protected what does everyone do when they extend a circuit? Add RCBO's? or mechanically protect the added cable? Not just for sockets...
