Great video as always, I really wish id had access to this level of information when I was doing my apprenticeship. I have a question too, im replacing a dual tariff CCU and the tails on the economy 7 side will not be long enough for the new unit (Iv had to buy double stacked). Can I use henley blocks within the CCU to extend the tails? There is no scope to rewire the existing tails as its in a block of flats. I just wondered if it was okay to extend them like this and have the henley block inside the unit? Any help or advice is greatly appreciated. Cheers
@learnelectrics4402 Жыл бұрын
Thanks for watching Kev and yes I totally agree. Where was the internet in the 70s when I was training. Henly blocks no problem, that is the standard way to extend. I used to torque the blocks up and then return to them after an hour or two of doing something else and just check the tightness of them. Copper creeps slightly when first screwed down and a second torquing is a good idea.

Very clear description. What is the situation with for example, having a small shower or garage "fuse box" with a 2 or 3 kw load, on the end of an existing 6mm2 T&E running from a 32A MCB in the main RCD protected box. Rather than directly from meter tails & Henley splitter block/s? Is this a problem? Should the small fuse box also be RCD protected or does this cause problems, having an RCD running off an RCD? Should a simple 2 pole isolator type of main switch be used on the small extension box & rely on the 32A MCB & Main RCD?
@learnelectrics44022 жыл бұрын
If the existing 32A supply is RCD protected that is fine. The garage unit, I assume will be an RCCB plus 1 or 2 MCBs, this is quite normal. If it was me I would use a 20A mcb in the garage unit and run the sockets as a radial circuit and 6A for lighting. Thanks for watching. Dave.

Hello, I've had an electrician remove an MCB circuit and use that to run an armoured cable out to another consumer unit in my out building, till then I was running all the lights etc from an extension lead, since he's done this my original house consumer unit it's tripping an RCD, he's blaming my wiring in my outbuilding, but it can't be as I was using an extension lead before. Do you think this is how he's wired in the outbuilding consumer unit into my house consumer unit? Thanks.
@learnelectrics44025 ай бұрын
Without actually seeing the install its difficult to say. This sometimes happens when circuits are changed or upgraded. You or the electrician need to investigate. Is it when any light is turned on, is it when all the lights are on. You will need to establish a pattern to it tripping. Sometimes, the extension lead will give just enough resistance to not cause RCD tripping if there is a fault, especially long extensions. Is the new wiring damp, sealed connections etc. Most electricians will come back and help you to solve it.

You may not get two meter tails into one hole on the main switch. From what you have said, it sounds like the second CU is only a small load. Rather than the main switch, put a 40amp breaker in the board to feed the new CU, if the original will take the extra load. Don't forget safe isolation when working around consumer units.

@learnelectrics44022 жыл бұрын
Don't ever think that you cannot do it. Lots of people are in the same situation, later in life etc. If you want to be a sparky you can be. 3 to 4 years not true unless you take the apprentice route or only approach this part time. A lot comes down to your determination and time input. To join a scheme like Napit or NICEIC etc. you will need to show educational achievement (exams) and practical skills (assessments, on the job etc.). Plus, the more you practice and read the better you will be. Make your own test board and wire it up and test it. Test your house, change switches or ceiling roses in your house. These are all skill building and good for the confidence. And actually go to at least two different training centres and put your story before them. Don't rely on the phone, turn up on their doorstep and ask to look at their training facilities. See what they suggest, the routes, the time etc. If they are going to take 3 or thousand pounds off you, the least you can expect is a fair chunk of their time and attention, not just 5 minutes, before you make a decision. There is no "Instant Electrician course" so be aware that some will try to sell you one and three week courses that guarantee you are fully trained (not). It takes time. Months in fact. The most important thing is being able to apply your theory to practical work. And testing skills are very very essential. Do not part with ANY money until you are certain that you have found the right centre. Speak to NAPIT for instance, their training packages are very good (I used to teach for them). They might be a little more expensive but they will give you good training. So will other centres too. Just watch out for the one's that promise that you will be an expert after 4 weeks. And I will say it again, read and practice over and over again. That's why professional snooker players are so good. They practice with the same balls on the same table in the same room for hour after hour after hour. And then they do it all again the next day, and the next, and the next. Good question. You can do it and don't worry about where you started, it's where you finish that matters. Dave.

Paul, two different things. A main switch (switch only) should be able to disconnect at least the maximum current of the circuit. Most houses are protected by a 100A incomer fuse. If you know the loading may be close to 100 amps at times, then a 100A main switch is ok. A fuse or breaker should disconnect before the maximum rating of the cable. If you know the cable rating is 14 amps say then a 10 amp circuit breaker is the choice, not a 16 amp one. Always protect the cable.
