    IP66 outlet sockets in garden area

    I'M not sure if you're allowed to spur 4 sockets off an existing ring circuit, I'm not familiar with the UK regs. What are the sockets for? Why so many in close proximity? I do know this work would be notifiable by law and would need to be tested and signed if off by a qualified person or you...

    Where do these parts go?

    That switch is an 'all in one' monoblock type construction, it's not like some switches where you get a separate fascia plate and grid frame and you can fit a variety of switch modules into it and fit different styles of fascia plates to the front.

    Where do these parts go?

    Yeah, as per westward, replace it because there's usually other small pieces like a spring as well as those brass contacts you've shown and they're not going to go back together. They're not meant to be dismantled and reassembled.

    What is it called IR testing?

    Yes for fault finding and troubleshooting which is the majority of my work analogue is always my first choice. The only time I would use one of those newfandangled MFT's (if I owned one) would be for EICR testing where you need a raft of test results recorded and entered onto paperwork.

    What is it called IR testing?

    I'm not sure exactly how they're connected but Kyoritsu is a Japanese manufacturer of very good test equipment and their testers are rebadged as Kewtech in some parts of the world. One of my other favourite tester brands is Brymen and they are rebadged as Hellerman Tyton as well sometimes.

    What is it called IR testing?

    My kyoritsu (kewtech) analogue insulation tester that I use as my daily driver has a locking test button and no delay or timer and they're still available brand new. KEW 3124A - https://www.kew-ltd.co.jp/en/products/detail/01122/. Maybe in the UK it's a requirement for them to be idiot-proof...

    replacing a dimmer light switch with a regular one

    Can you use a wire nut on a single wire? Does it grip with only one conductor?

    Unreasonably high invoice bill from an electrician

    You state your location as London. Labour rates are very high there and there's also often parking and other vehicle surcharges so I'd be expecting a hefty labour amount. If his brief was to replace bulbs and get the lights all working that may have involved some fault finding and some fittings...

    Ali-express DY4100 Digital Earth Tester

    The AliExpress tester is well within 10% of the Metrel loop reading which actually isn't bad for that type of test. Also please remove the plastic screen protector off the Metrel, it's going to give me sleepless nights.

    Green/yellow would have been Springbok colours... I'm a bit disappointed she went for All Blacks instead. Great to see you around, you had me worried for a while.

    How do you dress for an interview?

    I think smart casual would be appropriate as well. I also think personal hygiene is equally important, hair neat, closely shaved or beard and moustache neatly trimmed, hands and nails spotless, no bad breath and not reeking of garlic or body odour would be equally important. Also general...

    France

    Yeah, not sure why France has not had the honour of its own section in the Advice By Country area. I think that area of the forum is still a work in progress. Same with Scotland and Wales which from what I gather don't follow the UK regs although I'm not UK based so please correct me if I'm...

    Uh oh...shorted MICC. How scr*wed am I?

    24 ohms is far from a short circuit, even 0.4 ohms is very high for a dead short. If the conductors were contacting each other or the copper sheath I'd expect it to be a sub-ohm impedance reading unless the end of the cable where you're testing is very far away from your bending or fettling. Try...

    Uh oh...shorted MICC. How scr*wed am I?

    Visually check the cable for cracks where you bent it. You can bend Pyro fairly tight but it doesn't like being straightened again, it loses it's flexibility after the first bend and it often cracks if you bend it back again. What was the resistance between the L, N and E? If you've got a low...

    Electrical Layout diagrams

    This is a bit of an old thread so I'd guess the people asking questions already found their answer but many manufacturers and suppliers have CAD free downloadable files for their products on their website. I do use AutoCAD MEP for extensive 3D and 2D drawings with multiple layers for different...

    Medical Question

    I wasn't going to get started on torches, flashlights and worklights, that was going to be for another day. I've got dozens, literally dozens of torches and worklights. This weeks addition was a Streamlight Syclone. Did I buy it because Streamlight is my favourite brand? No, I love any good...

    How to wire led light

    It's a constant current driver with a universal 85-265 volts AC input. Connect your live and neutral to the black and white wires respectively. The driver says it's double insulated but I'd also find a way to connect the earth wire to the metal chassis of the light if it were me.
