    Is it compulsory to use the flex outlet on a fused spur?

    Hi all, BS1363 Switch fused spur with flex outlet has been installed. But the installer hasn't used the flex outlet, they've used singles in conduit and the cable grips are still in place on the spur. However the client has challenged this, implying it should be changed out to a standard spur...

    UK Ring running from fused socket

    Hi all, Hoping you can help. My house has a ring in the kitchen that is no longer wired direct to the consumer unit as it had a fault and kept blowing. It was believed that it might be an 'open ring' and a socket had been removed from the ring at some time in the past. (I think that was what...

    Fused spur rating for electric underfloor heating

    Builder installed 175w / sq metre in an area 6.7 x 3.5. What should the fused spur be rated at and should it have a contractor as well? Am I correct in thinking it is drawing just over 17A therefore 13A fused spur is insufficient? Thanks

    Replacing fused switch with Smart Switch

    In the hallway we have a fused switch that operates the towel ladder in the downstairs bathroom. Any possible issues in replacing with a smart switch? I don't know of any with an integrated fuse.

    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...

    Switched fused spur or I switched fused spur?

    Hi all, a friend has asked me to install him 2 sockets behind his wall mounted TV as to hide the cables. Obviously he wants minimal damage so extending the ring isn’t an option as the nearest sockets are low level on an adjacent wall and are fed from above (he’s also made it clear we can’t come...

    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...

    Which is better BS1361 or BS88?

    Was wondering why was BS1361 replaced by BS88 even though BS1361 tends to have a larger breaking capacity according to the on-site guide if I'm reading it right, however, I maybe wrong. For example BS1361 breaking capacity can be 16.5kA to 33kA depending on what type you get, where BS88 is 16kA...

    Setup: Consumer unit fed via sub main from a 60A fused isolator switch. This is connected to the service head MET via a 2m earth connection. How would one go about both calculating and documenting the Zs? Would you be treating the fused isolator switch as it’s own db and therefore be...
