    Lighting from fused spurs

    Evening all. Your thoughts please: I was helping out another spark today. The job was to spur from a ring final to a 13A fused spur, to feed several sockets and some lighting in a loft conversion. For the lights (regular common or garden pendant sets) he asked me to fuse down further to 3A...

    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

    Ring finals and fused spurs

    Evening all. The OSG says "As a rule of thumb for rings, unfused spur lengths should not exceed 1/8 the cable length from the spur to the furthest point of the ring.". Okay, so what is the maximum length for a fused spur then? I don't seem to be able to find the answer in the OSG or BBB...

    Ring main consisting of only spurs

    Hi, this is my first time on this forum so I hope I'm in the correct section. I've come across a strange socket wiring set up in my own home. I was baffled at first as to how at the consumer unit I had a ring main set up (2x 2.5 T&E fused at 32A) but radial setup at each socket (1 cable). What...

    Hi I recently purchased a house (built and wired in the 80s). I removed one of the sockets to do some wallpapering and I noticed that it has 4 hot+neutral (+earth) wires connected to the double socket (and I'm assuming it's all solid core 2.5mm wiring??). I'm not sure if it's connected in a...

    Spurs off Spurs on radial circuit

    So you can spur off Spurs on a radial socket circuit, is this because the cable is protected via a 20amp breaker at the board compared to 32amp on a ring?

    Hello all.. I have recently added a spur for a customer and it got me thinking again about how many spurs could I actually take from the same socket! The only socket I could use to take the spur from was on the ring and was already feeding a spur. Now I could have extended the ring but after a...

    Ring Circuit Question

    Hi all, In my house I have a ring main which covers two floors, from which I have created two spurs with 2.5mm cable. I am drawing 3000W on each spur and on the ring sockets probably around 500w making a total of 6500w. Do you think this is dangerous as it is exceeding the 24A rating on 2.5mm...
