3 in.lbs? Easy to exceed that with a jeweller's screwdriver...


Yep, a mini-block on a pcb, its just an example - thats all.


That's good enough for me....


Perhaps. Doubt it has any relevance to speaker terminals, though.

Very relevant I would have thought with bare wire connections.


They're likely to need checking once in a while through vibration.

Exactly!

Your SON? Busted are strictly for pre-pubertal girls. He is going to

That's *exactly* why my son likes them. I have to confess that it's

howling "I've been to the year three thousand" though. Maybe he'll grow

Good grief. Considering the number of such terminals in the average house
carrying a great deal more current, I'm surprised there's not fires
everywhere. ;-)

That's why house wiring is required to be solid core, and plugs have
fuses in them................

BTW, that's still good advice even if you are wiring a house - go
round the junction boxes again the next day. You'd be surprised how
often you'll get an extra half-turn.

Lets hope he lives a long time - remember that if he lives those extra
two thousand years he gets to meet his great granddaughter.

I use a lot of MK stuff... I find cheapos will not tighten enough for my
liking. Solid core wiring stuff rarely works loose like flex anyhow.

However, far more under tighten than break them. Due to using a silly
small screwdriver.

Indeed - right tool for the job... Now where's that kitchen knife love...

great great great granddaughter, and it's only a thousand years, so that's a
nice, believable 200-250 years per generation, not the far fetched 700 years
you just made out....

Yeah, and we're just *bound* to have evolved gills by then, it stands to
reason. Shoot them on sight, I say, and bring back The Birdie Song.

On the other hand...

Its just informing HiFi folk (who are generally fussy) that they can tighten
down connections some more - no harm in that. Considering houses are not
subject to constant vibration this hardly applies to domestic ring mains,
cookers etc. Actually there are quite a few incidents of arcing and
localised heating due to loose 13A socket terminal connections but because
the area being metal clad and grounded it generally goes no further (ask any
leccy)

Quite.. even then my 9 Y/O daughter has outgrown them.

She's taken an unhealthy interest in heavy metal;(
