    BS88 max ZS table for fuses over 63A TT or not TT

    Hi First time with this kind of a job for me.

    Another video on fuses versus MCCB

    While idle on YouTube I saw this video showing the comparison of HRC fuse and MCCB with some spectacular results at high (63kA!) but in-specification faults:

    I hope someone can help me understand this. I've just replaced both my florescent tube lights with Energizer LED tubes, and they were fine for about a week but last night the starter fuse in the kitchen light blew. This afternoon I swapped in the starter from the other light and it too...

    3/5/13 Amp Fuses For Plugs And Fused Spurs...

    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...

    Blown fuses... lucky dip!

    Automatic stock saw. Coolant pump fed from the same contactor as the main motor but via MD 2A fuses instead of an O/L relay (the main motor, stock advance motor and hydraulic pump all have O/L's). Ate the fuses last week, tested the pump motor for IR and winding resistance, all good. Ate the...

    Main fuse protection

    In our house the main fuse is rated at 100A maximum. The individual circuits in the consumer unit, if all used simultanuously, add up to much more than 100A. Now I understand this is common practice as it is assumed that not all circuits will be used to their max at the same time (the...

    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...

    Are we allowed to use 5 amp fuses in 13 amp plugs?

    I work for a charity (Besom) that gets equipment that needs to be PATted. A lot of these come with 5 amp fuses. Please do the regulations allow you to use 5 amp fuses, or are you supposed to change them to 3 amp? Most of these devices are low power & they will run perfectly well on a 3 amp...

    My motorbike has no power. Battery charged, fuses checked, power is going to the starter rely but not beyond....please help.

    Recently changed my starter relay on my xv1600 wildstar. When reattaching battery cable, it caught a small thermostat and sparked. Now whilst I have power to the relay from the battery I have nothing beyond the relay and turning the key does nothing. All fuses have been double and treble...

    UK BS88 fuse board on a new installations

    I was wondering, are BS88 fuse boards still used on some new installations especially industrial and even commercial. And if so would that be ok with the regulations or not because its not retrospective. I know they are quite outdated and its hard to find a electrical wholesaler selling BS88...

    Pulling cutout fuses

    We see a lot of threads asking what to do about isolation for a CU replacement with lots of talk of the seal fairy and just getting on and pulling the fuse. It gets me wondering whether you do the same outside of the domestic world? Does the seal fairy visit the heavy duty (over 100A) cutouts...

    UK How-to make this US plug work in the UK? [help please]

    So I'm based in the UK and I have bought a lava lamp that came with a US plug. After blowing the light bulb (which was also US and was a pain to find and replace online), I clipped off the plug and wired in a UK plug instead of using the travel adaptor. Now it just won't work/ turn on. On the...

    Why do we use cartridge fuses and not MCBs?

    A customer asked me this today and I couldn't answer. Why, in LARGE switched fuses (60-100amp) do manufacturers use cartridge fuses and not MCBs?

    Background: House was built early 1980s, fuse board is mostly the old school ceramic fuses. The wiring is said to be of modern design with 'tough plastic sheathing' according to a pre-purchase inspection. The previous owner has replaced a 5 amp fuse for the lights with an 8 amp circuit...

    Fuses blow when I put phase and ground wires in contact even when light switch is turned off

    Hello to all, I stumbled upon a strange problem this morning. I wanted to change the light bulb socket in my bathroom, when I noticed that when the ground and phase wires come in contact,the fuse-box trips even though the light switch is turned off. So I took a pen voltage tester and tested all...

    A Thread About Boring Old Plugs And Fuses

    Nothing much has changed with them since the beginning. Perhaps now a lot of things come with moulded plugs and you don't need a screwdriver to change the fuse except perhaps for popping it out. And for people with no knowledge whatsoever can put a 5amp fuse into the washing machine and I guess...
