    Extra spur advice - fuse needed?

    Hi, I need to run a spur from a main ring socket, however, it already is supplying a spur ( double unused socket ). Is the only way to disconnect the unused spur? Or can I incorporate a fuse? What's the safe way to do this please? Thanks

    How do fused spurs FCUs work.

    Hi, quick question. How do FCU's work? Do they just protect the load side and what I mean is, say you have a ring final with 2.5mm^2 protected by a 20a mcb at the consumer unit and you add a fused spur on that ring de-rated to 3a to supply a 1mm cable for lighting. Now say you start turning on...

    UK Both sockets in one bedroom are spurs

    I've noticed that both sockets in one of my bedrooms are spurs, they both have just the one cable going into them. I checked the nearest socket in the bedroom next door but that only has two cables going into it, so they can't be feeding off that? Anyway to tell if these two sockets are safe and...

    Ring Final Circuit - spurs only

    I read that it is against the regs that a ring final circuit cannot be just a ring with with spurs off it. In short, a ring must have sockets on it which double up as junctions. I find that hard to believe.

    Hi... I moved house fairly recently and I'm slowly uncovering 'quick fix jobs' all over the house from paint, render and now electrics.. I came across some electrics in the garage and I'm curious to know why they've done what they have and is it correct in any way, shape or form (and safe?!)...

    Ring Fused Spurs and overload protection (433.1.204)

    Just a quick question from a new qualified sparky. So in 433.1.204 when it says the Iz of the cable must not be less than 20A for a ring final circuit. Does this include a radial fused spur taken off the ring final? If you install it in 2.5mm in trunking then the Iz is immediately down to 20A...

    As most people really don't have an understanding of electricity whatsoever, and the amount of times I have come across the wrong size fuse in a plug or FCU. I don't know but surely this should be addressed somehow. Moulded plugs are all good as well on the new table lamp somebody has just...

    2 fused spurs

    Hi I wondered if anyone can offer some advice we bought a house and replaced the alarm, the installer said he would need to install a fuse spur. A year later we found another fused spur in the bedroom which once I removed the fuse it cut the power to the alarm. Is it ok to have 2 fused spurs?

    Just checking my understanding of spurs off rings

    Have 18th ed and page 505 does say an unfused spur should feed one twin socket outlet. However if a 13amp fused spur is then connected to this and then to another socket is this not permissible? I can't see any potential for cable overloading? Thanks
