    BS 3036 fuses not allowed for new circuits!!

    This is what my assessor has told me! He states that the BS3036 does not meet the 0.4s disconnection times and cannot be used for any new work. I do not have a BRB so cannot see the disconnection times for a 3036. Surely he is wrong? He is suggesting that we have to change the 3036 if we want...

    Old cut out fuses

    Evening all, I am looking to get hold of a 40 amp cut out fuse to replace an existing 60 amp to provide adequate protection to a supply cable. I bought a BS1361:1971 fuse thinking it would be the correct fit (22mm diameter) but it turns out its about 2mm too wide to fit in the carrier. The fuse...

    Eicr remedials

    Main switch 160a bs88fuses, 35mm tails feeding busbar chamber with switch fuses ontop feeding distribution boards. A c2 has been given to undersized main tails. I thought that because the tails are only about 400mm long from switch into busbar that it was ok? Thoughts?

    BS1361 fuses

    I'm doing some past papers for my 17th exam this week and have found 2 questions about bs1361 fuses - their operating times and max zs. I can't find any data in the regs about them. Am I being blind or are these questions pertaining to old regs that have been removed from the current edition...

    Hi, I have had 3 phase cut-out and meters for 3 flats moved from my cellar to outside meter cabinet. Sparky has installed switch fuses and around 15 metres of SWA for each flat to relink to old supply point. Work looks decent so I am not disparaging said sparks work. I have a query though. He...

    Fuse characteristic

    Hi, I'm currently studying for both my 2394 and 2395 exams and I've been thinking of scenarios to test myself of certain theories, I thought of one where a garage board would be fed with a 13a fuse spur with only a 1.5mm armoured buried under ground. So I started thinking about fuses etc and I...

    DNO Fuses In Flats Replaced By Dummy

    Now obviously I have not seen this with my own eyes as it would involve pulling possible DNO fuses which I would never do...but I have it on good authority that there is a certain small block of flats where each flat has, in a meter box outside the front door, its own meter and what appears to...

    Been to a job where a young couple want to replace their white sockets and light switches with chrome finished. I took a look at their CU and it is a wylex re-wireable fused board with separate RCD covering all circuits. It then became clear they had no idea what a rewardable fuse actually...

    Separate fuses for 3phase supply

    Hi All, Just trying to double check if there's a reg suggesting a 3phase circuit should have over-current device that disconnects all line conductors at once? Got an old rewireable board supplying 3phase motors with 3 individual fuses. I'm looking at 530.3.1 ................... Can anyone...

    Hi everyone. I'm doing some work on a farm and came across a problem. The DNO head has 60A fuses in but down stream of that is a 3 phase MEM Glasgow switch fuse with 100A fuses fitted. Obviously there is no discrimination whatsoever there so I explained that the fuses need to be downrated to 50A...
