    Fault on lighting circuit

    What does L-E measure at the board when using a low Ohms test rather than an IR test?

    12 volt bulbs on 240 volt circuit

    Very good point. I'd forgotten about that. But unless you fixed it then it was more likely that other bulbs would fail due to receiving slightly higher voltage.

    Did you put the units at the end, ie. 'A' ?

    12 volt bulbs on 240 volt circuit

    Hence why if you remove one bulb, all the rest go out as well

    Signal generator amplifier using only positive pole output, underperforming

    If you don't match the load to the output impedance requirement of the amplifier you won't get maximum power transfer to the load. You have effectively provided the amplifier with an infinite impedance load. You may well also damage the amplifier. Could you not calculate the length of wire...

    Problems with my roof

    Interesting. I've got a very similar extension at the rear of my house. Was built around 10 years ago, and signed off by the council, but like yours it is built onto a cavity wall and has no cavity tray. We've never had any water/damp issues at all. It does have the lead flashing cut into the...

    Voltage Drop Calculation vs OSG

    Convert it to a ring circuit maybe. Assuming you do actually have excessive voltage drop.

    BBC micro, how posh. I started on a Vic 20. Although we did have BBCs at school. I did get told off a couple of times for using network commands to target other machines on the ethernet network. Is it Repton you're thinking of? That had a tool where you could make your own levels.

    Hello World!

    Mine is a Telequipment D75 from the 1970s. Still working spot on. Proper dual beam as well and very high EHT for really bright traces.

    Old film stuff

    Yeah the name ended up being used for the production of some really tacky digital cameras etc. Much the same way as Goodmans went and several others.

    Old film stuff

    There are still companies around who will develop film. Don't take it to the local Boots store though as they may look at you funny :-)

    Xmas lights

    Seen similar myself. It's scary the amount of stuff out there that doesn't comply with standards.

    DIY - new oven tripping DB.

    And fully tested it with an MFT obviously

    Xmas lights

    As mentioned above, that plug does not meet regulations purely on the sleeved earth pin, which is a definite no-no. I suspect the body dimensions are also not sufficient, but difficult to be sure. Non compliant and shoddy. I wouldn't use it.

    Why does my immersion switch keep melting?

    Ah just saw the g/y earth colours and didn't look much further. Usual suspects would be cheap/old accessory and/or poorly made connections.

    Why does my immersion switch keep melting?

    What's the deal with the short link in the Lout terminal?

    Convert kiln from 415 triple phase to 240v

    I don't see the fire risk with that, assuming the connections and incoming cable are secure and made off well. It's only a big oven with heating elements. Different kettle of fish to not earthing SWA armour surely?

    W3D4 I’ve won another comp!

    UK Hanging a 30kg Chandelier

    As above - I don't see how you will be able to rely on a single point of that frame sipporting 30kg. If it was me who had installed the frame then I would void any warranty
