Where else besides the UK do they use fused plugs? I don't recall ever seeing them anywhere but there.
@BuyitFixit
@BuyitFixit Жыл бұрын
A quick google search says Only the UK, and other countries rely on the consumer unit. The maximum fuse in a plug is 13A and often on a 32A beaker in the consumer unit and wired as a ring main with other outlets. I guess if the cable was rated at a couple of amps as in a lamp for instance and it got damaged, the fuse in the plug would blow instead of sending 32A down a cable rated for couple of amps.
@inothome
@inothome Жыл бұрын
@@BuyitFixit Yeah, maybe remnants of times past with fuses in the CSU and the prevent blowing the whole circuit? Cheaper to replace a device fuse than the ring main, maybe.... Now with breakers just an old regulation. Not a bad idea by any means though to have the devices fused. In US you can have 25A branch circuits and devices you plug in can have #18 AWG (1mm or so) and you never hear of things melting down. Here in Vietnam, same thing up to 32A, but way more electrical scaries here! No grounds / earth. TT system, not a TN-C (or C-S). So of course, no PME either. But, has it's advantages too, less fault current, but that can also cause breakers not to trip. Pros and cons to all systems. RCDs are becoming more widespread now here too. No regulation as far as I know, but I do recommend and install a lot of them. The price difference for an RCD here VS RCD (GFI) in the US is crazy. $10 USD here vs $100+ USD in the US. From same manufacturer too!

For fine stranded conductors class 5 and above for use with screw terminals bootlace ferrules should be used to no only protect the conductors from the screw but also to ensure a good electrical connection as the conductors will splay out under the screw causing only partial contact with the conductor reducing the current carrying capacity. As the plug was non compliant I would be that the conductors used in the flex are copper coated aluminium so I would be checking if it is capable of carrying the current the load requires.

hey thanks for all your vids.. love to see a genius at work.. With the drum machine there's the 9V AC input power supply. How does the power section on the main board work to provide dc with two diodes which impiles full wave rectifier .. but you need centre tapped AC for that. There are two diodes... so does that mean the ac is halfwave rectified for two rails? and the AC- is that used as is within the drum machine? If not you could use a dc mains adapter - the dc would just sail through the rectifier diodes and all would be well. Maybe opamps and DAC's require the AC rails..but they then need the 'middle' 0V don't they? Sorry questions and no answers.

🐨This device should more than likely draw well under 500 milliamps when operating properly, NOW... See that transformer @4:19, Well that suckers primary winding should burnout at around about an amp, 2 amps tops if it's maximum and I stress it's maximum current draw is exceeded. Having said that, this would make any fuse greater than 1.5 amps redundant so I suspect some hack couldn't get their mitz on a properly rated fuse and therefore that massive 3 Amp fuse was installed, and as a comparison my 250Wrms Subwoofer uses a 5 Amp fuse at 240V. BTW there is a formula to calculate the transformers specifications if the various voltages and nominal current draw is known if one wishes to protect the supply transformer without it burning out the fuse prematurely.

The drum machine - backup battery - is too low - below 3.05v usually means it is almost flat…. Needs replacing… I change the coin cells at less than 3.1v…

Thanks for that.I just did a quick search on the voltage curve, bearing in mind that this is still in circuit, 2.8v and below is what it suggests for replacement.

@@BuyitFixit I used to work with repairing computers, and when the battery was below 3.1v, you would get weird errors. The practice was to change the battery if below 3.1 v, and reset the cmos memory, and this fixed 90% of the weird errors. The battery may not be flat, but the rest of the circuits may not be happy with a low voltage…

@@markfiddament9383 Fair enough 🙂 I used to repair and build computers too. First one I build was a 386sx25 with 4mb ram and a 20gb MFM hdd, and an adlib sound card 😂😂 The first computer I learned to program on was a Nascom2 that a friend built around 1980

I read somewhere China uses C E not to be confused with CE , claiming it to stand for Chinese export. Right.....

Thanks 👍I wasn't sure if it used the AC for timing or if it generated a negative voltage for the OP amps with it. I've got a 24v AC PLC and that doesn't work on DC when I tried it.

@@BuyitFixit Hi if you look at the European CE mark you will see it is a different shape than the Chinese CE (Chinese Export) they do it to kid people into thinking it has European Certification also if you see any of them unfused plugs chop them off.

Oh right, I didn't know that. I thought they were copying the European CE mark, which I guess they are in a way... Yes, I've had a couple of devices with those horrible plugs on. I usually change the lead for a decent one or as you recommended too, chop off the plug and fit a fused one.

Yes I usually do. Mostly the plugs I've came across were on leads so I just binned the lead and used a decent one.

Yes you have to be careful with the CE mark. That was a fake but in China they have their own registered CE mark where the E is embedded into the C, it looks similar but does not register as European conformity

Different parts of the world say things slightly differently to what may be considered grammatically correct. Slang, dialects etc. At the end of the day, my videos are about repairing items, and are not lessons in English or Grammar.

How nice to see another dangerous and completely illegal chinese plug on that Ultrasonic unit! Is the CE label "Conformity European" (in French!) and tested or China Export which isn't? I would suspect the lead is very thin copper plated aluminium too so I'd change that. In addition it should be three core (earthed) as the transformer bolts are contactable and I would be 90% sure that the insulation will not conform to double earthing requirements. Basically electrically unsafe!

The cable actually didn't look too bad. When I've had items in the past with these plugs,it's usually on a lead. I just bin the lead and use a proper one 😂😂
