*FALSE* The real Thomas has expired from a sexually explicit encounter with the neighbours SELV installation, along with the two adorable poodles, Dobby and Winston.
Fault finding by halves does not stop there, half it again, and again if needed... Also, if it is water or degraded insulation, using a high voltage insulation tester (“megger”) is far faster rather than waiting for a RCD/RCBO to trip (or not).... Especially if the total earth fault/leakage fault is made up of a combination of small earth faults/leakage faults, which on their own don’t want to trip the RCD/RCBO while you’re there...
Ha Ha love the dog :-D iv'e been to a few where the dog requires ball throwing pmsl. I love fault finding, gets the grey matter going, great to see ya back Tom.
"I'm not throwing that ball again" *throws ball* dogs just melt our resolve don't they! We're not even meant to allow them in the house while we work (big company) but do I fuck throw the dog out their house in the cold!
Tom, a tradesman, typically has periods of lot of work: *doesn't upload* The internet: hes dead (totally ignoring the fact your a tradesman) The way the internet jumps to conclusions is a bit odd sometimes
If the moisture is from condensation it is effectively distilled. That means it is almost non-conductive, so it won't trip an RCD. Water ingress, carrying dissolved salts will trip an RCD quite easily.
i had never thought of that. Im going to have to test this now to satisfy myself. But your right i have heard the thing that distilled water is not very conductive, i just had not thought of it in this context. good point
I've found that rarely is it water that directly causes the problem. Water seeps in,and at that point all is working. Then over time the water begins to corrode, oxidize, and rust any metal components in the box. These contaminants are what then cause current leaks tripping RCD,s
Those big transformers are wirewound, as opposed to electronic. The electronic ones that pump out high-frequency AC don't work with long cable lengths, because the cable capacitance has a significant effect at those frequencies. The output splits ought to be sub-fused I reckon - that's a 25A source. DIN-rail mounted fuses and terminals with jumper bars are a neat way of doing this.
In tech work, the strategy of splitting something in half in order to find an error or issue has a handy little term called Bisection, in case you're looking for a term for it! 🙂
We only saw Laura ounce. I got asked by a customer why her lanterns along the wall on the drive were tripping, the glass in every one was broken and they were all filled with the Bush that was growing around them, could barley see the lights.
"I've come across significantly worse." I miss that old video of yours where you show of an installation in the basement and just ask "why?" while looking at it. Someone truly outdid themselves when a professional looks at their work and confusingly asks "... but why?"
OMG what CRAZY wiring "installation" above ground... and in that crap plastic "conduit "?? Above ground?? People actually pay you for that?? 😆 Above ground wiring connections on little poles is equally crazy, just begging to get bashed around & broken! And ugly! Yikes! Have you ever heard of copper crimps & grease tubes? Only way for truly moisture-proof connections. 100% of my thousand of wiring connections are underground a still better sealed & protected! And MR16 bulbs suck! Delicate, not much light, delicate! I have Par36 LED below-ground well fixtures on same bulbs for going on 8 years now!
this is really similar troubleshooting i do every day as a telecom tech i work in the outside plant mostly buried cable, luckily we have very nice test equipment my number one tool is the TDR you can read your cable pair and it gives you a pretty accurate footage where you fault is but you can always rely on the old school method of cutting it in half and isolating your trouble
Have you tested Plejd bluetooth dimmer? You can dim from a regular switch, or with your mobile phone, or have programmed scenarios or astro clocking on lighting. And you can make smart lighting at a cheaper price than KNX for example. And it's a lifesaver if your customer wants to be able to control the lighting in some odd way in a room. Almost all electricians in Sweden have a Plejd dimmer in their car. And of course Plejd dimmer is Made In Sweden. 🤘😎🇸🇪
Just came across one of your columns from 2017 about "live fizzy fruit drinks". My comment:- Live culture drink. Easy to make from scratch. Flavour depends what fruit juices you put in. For ginger beer/ale:- Thoroughly crush a piece of root ginger about the volume of 2 hen eggs, put in a 1 - 2 litre saucepan. Add about 1 to 1.5 cups sugar (brown or white or mixture - but brown will give additional flavours), add lemon juice (about half a cup). Bring to boil and let cool to blood heat. Tip into a sterilised 3 lire (or 1 gallon) plastic bottle (that has been used for edible content) and add about 1 tablespoon dry bakers yeast granules (brewers yeast would be better - if you can get it) and add cold boiled water, but leave a few inches free space at the top for the bubbling and foaming that comes with the fermentation. Plug the opening with a wad of cotton wool (on no account put screw cap back on!!!!!!!!!) Place in a slightly warm cupboard for two to three days. It will start fermenting and give off a lot of bubbles of carbon dioxide - hence the cotton wool to allow gas to escape. More sugar can be added if a stronger alcohol content is desired. Ditto after drinking some of the content, some more cold, boiled water can be added if the ginger taste is a bit strong for you. When ready to drink, it can be refrigerated for a short period -- but you will probably drink it rather than just let it remain too long in the fridge. The appearance of this drink will be cloudy. This is natural, and is mainly small bits of the live yeast floating in the fluid. Beware if driving. It definitely is alcoholic.
The issue with mains voltage garden lights is normally a build up of multiple fittings, each with a small amount of earth leakage. These leakages build up and added together trip the RCD. Always best to fit low voltage garden lights. No earth - No earth leakage
That's the best type of dog to work with ! Should appreciate him! Worst dogs are the ones that bite. I've been trades for 35 years and been attacked by two dogs. 1. Alsatian. ( not too surprised) 2. Black Labrador. ( fucin surprised) Great vids buddy!
I have 0 clue about all this sorta thing. Bit nothing I enjoy more after working, is coming home doing what needs done and watching all these videos. Something therapeutic about it.
Thanks for the video again TOm, excellent as always, love the dog. What, though not expecting an answer, did happen to Davey Boy? Hope you're having a good week....
I my garden, I've had problems with foxes chewing right through garden lighting cables, none of them now work, I think I'll just stick to solar ones from now on!
Those Oase pond filters are brilliant, but oh my God, cleaning them out is disgusting. Then the seal goes on the UV lamp holder and fills the lamp ballast with pond water.
so weird that i can go to work all day fucking about with cables fault finding and then come back and watch 10 minutes more of it?? good to see you back tho Tom x
In the outside junction boxes why don't you give everything a good spray with water dispersant? Also that light that was flooded. Grease round the cap thread as bet most of the water is getting in there since it's flames at the other end
News flash! I’m hearing that Tom the spark has been taken out by a big ass garden spider. Hence Dave and Laura have had to get a CGI version of Tom, but due to the time taken to render the images, the video feed now takes a couple of weeks to make a short ten minute video 🙁
Behind the scenes question... In the opening shot the view is of you climbing up the side of the van and captured on camera from the vans roof. Was the cameraguy perched on the roof or had you placed a hand held camera on the roof?
On Lithium grease, it’s great for metal to metal connections, but it’s petroleum based so it will eat rubber seals and plastics. Silicone grease is a better way to go and does the same job. You can also use it to improve the water resistance of exterior accessories.
Those pump filters have a drain diversion valve on the top! There will be a drain outlet on top. Run the pump, turn the valve (make sure its pointed at a drain) and there will also be a spinny handle thing to turn to wring out the foams inside. I think. Then all the gunk comes out of the drain hole. Obvs only works if you have a drain!
We know that is not you Naga, It is amazing what they can do with CGI .They did the same to Oliver Read in the Gladiator ( google it ) Rest in peace my friend.
