The smoked consumer unit video

I've seen that Video of the CU board by nick bundy

If you have a look at the wylex mcb you have they are marked load and supply. I personally cannot see why they mark them as on ac should not make a difference. On fitting to the board the problem is the din rail fitting.

With AC the direction shouldn't matter too much. It's more of an issue with a DC breaker.

while watching this video it reminded me of a wylex TP & N Distribution Board where if you look at the MCB they are marked load / supply. Well this board someone had placed the supply to the centre load input except when it came to the rcbo which was mounted as instructed so this one breaker switched in the opposite way. So question for tonight is does it matter which was the flow on MCB I was told the spark may not quench correctly?

I've got a 17th Edition plastic distribution board here, and it's inside a wooden cupboard, so if it goes up, it's really going up! At least it's not Wylex, but I'm sure it's just as cheap.

Now that these breakers are "public".... there is no more resale value on eBay.

It's fine. Give er a good scrub with a toothbrush n she'll be good go again.

Interesting coincidence that I get three burnt out autopsy videos in a row on Patreon, first from DiodeGoneWild of a laptop power supply with a sooty PCB. He even tried repairing it and it blew again. Then this video. The third in a row is Julian with the charred remains of his burned up solar charge controller. Luckily his fence didn't catch alight.

The distribution equipment is usually well rated, so even if heaters were plugged into every socket the breakers should trip before damage occurs. It would be a very expensive way to heat their house if they did that.

It might be beneficial as it would contain the separate strands. But even better would be deeper connections and two screws as used on some isolators.

Ouch. Well lesson learned 😭 sometimes life is the cumulative lessons we learn, like don’t play with the stovetop😂 For all the good trade-schools mine was don’t agree to the price without already getting 3 offers. Some water guys just resell old water heater units. They make more on the labor whdn ‘its the tank’ instead of inspecting the parts checking the thermocouple, valve, etc BC mostly showed me how for everything you take apart with care you can put it back again 🤯 i was never a tinker youngin

I'm not an electrician, but would terminating the big incoming tails with a nice beefy and well-crimped ferrule stop any potential movement of the cores? Or is that not permitted? Maybe that would cause problems in itself.

I got so taken for a ride by an electrician I am ashamed of myself for not thinking properly at the time but I was very ill and on a lot of pain killers at the time. I had already replaced my consumer unit with a modern Mk unit I bought from my local electrical wholesaler. When I had an issue with my cooker throwing the RCD a person I met through a local electric chat group offered to come round and test it for me. He told me it was illegal because it had a plastic housing that can catch fire but he could replace it for £200. Like and I an idiot I said yes. He came round the next day and took it off and slowly replaced in over the next two days before he asked me for even more money to finish the job because it was still "Illegal" and disconnected my whole supply When I realised that not only had he taken my brand new MK away and I remembered that I had bought the fusebox and housing they were all individual and could be replaced. That meant that he should have just replaced the case and that would had been it. In the end I had to call the police who retrieved my old MK unit but not my money. So the moral of the story is don't make decisions about electrical work when you are extremely ill and highly medicated. You should put all the bits in a case and sell it on Ebay Clive.

Just thinking could they have put to much load on it from sum were in the house like they ran a load of heaters sum of them can pull 3Kw or more so if you had 4 or 5 in the house could be a big load and it just found the bad link in the bored like you pointed out they did not do the wire up so goy hot they well up it goes ? By the way another nice vid BIG THANKS :)

Interesting to see - yep was taught the same when terminating, and once tightened wiggle it and check again. Plastic consumer units - remember when they where first introduced and how quickly they became thin bendy plastic with the smallest bits of metal possible in them.

That was crispy, crunchy and oh so satisfying.
