In the last video I was looking at this little pump and it came with this adaptor and I thought I'll check the adaptor out
and when I did I found that the earth pin is not connected to the metal inside
continuity in the metal pin itself
but nothing to the metal work inside
so I think we should explore this further
this is also a good time to introduce my new toy. Its..er.. another Amecal meter and Amecal actually
got in touch and asked if I wanted a meter just to use just as an extra meter
just to play with.. and I chose this meter here because its one of the more down to earth ones
and its got this massive display.. its huuuuge... and its also manual ranging
its a nice simple meter. It costs about forty four pounds, its very affordable, and the crucial bits..
it has category three and four input protection.
er.. and then Amecal actually sent me some extra goodies, including things like this
They saw from my videos that I was an electrician
and they sent me this clamp meter which is specifically intended for 'leakage current testing'
so I'm going to cover this in a separate video becasue it is such an interesting little meter.
It really is designed for sniffing down earth leakage fault currents... very neat because its got a 200 milliamp range
which is accurate to about a tenth of a milliamp.. its just really unusual to see that.
So ..er.. yeah, this is going to feature in another video though.
In the meantime, enjoy this bigger display.. thats nice, I do like the display in this..
and..er.. we'll actually open this plug right now and take a look inside,
because.. um.. something is not connected in here.
Oh.. before I do this.. I'm going to put this screw back in.. because
this .. err... I've feature of these horrific adaptors in other videos
and, er.. here's the standard British square pin plug. Its got the big stout earth pin
and I've shown in other videos that you can put it the wrong way up, you can defeat the earth.
You can put it into the live outlet.. er.. and then the current would flow through the load and then this would become live
but someone else pointed out the piece de resistance. This is just unbelievable..
Earth pin is connected to the metalwork of the appliance... it goes directly into the live pin, the live socket!
So you could make a whole appliance live accidently if you were fumbling around and plug this into this
thats just ... or even if kids were playing with it, because you know, it's just like lego, it's a toy
and the fact that you can do that is just horrific..
but anyway, lets open it up and take a look inside
and see why that.. er... earth isn't connected. Cos it does look like it goes all the way back.
Never worked out why it says
"FOR EXPORT ONLY".. that.. that kind of explains things
...(gasps)..
that
these are just.. these screws are holding the pins in and
they just press against.. the metal?
and the earth actually looks as though it's actually sticking down further
than the others.. so thats why its not making contact, cos its actually further away than the others
I wonder if it actually makes decent contact with those ones
It was making continuity,
but then its just barely, because there's just the tiniest bit, you know it closes up almost completely
before it looks as though it actually makes connection
They're horrific. They are worse then I even
remember.. seeing before.
That's just bizarre...
They're terrible
err.. but then again, we kinda know they're terrible and I'm not sure
I'd rather actually they didn't send these out
I'd rather they just said , you know, find an adaptor yourself and go somewhere and get a standard
shaver type adaptor
but, these things are no good at all.
Yeah, thats interesting
I really should cover, there's more than one type of this
I should try and find an example of each and then we can explore them
and just see how well they're made
Hopefully they're better made than this one
but yeah, yeah, thats quite interesting
