On older boilers (furnaces if you're American), when the

The basic problem with english engineering is that it
hasn't
advanced much beyond the 1500s. We superior Americans,
however,
employ the use of electronic ignitors.

As do we with new boilers. But our stuff must last longer
because
a
lot of folk still have one with a pilot light, the only ones
that
don't are the morons that thought they should spend £1000 to
get
a
boiler that will save them £50 a year on gas. So you make a

in 20 years time, why bother? My boiler is at least 25
years
old
and I've only ever replaced the thermocouple for £7. It

newer fancier boilers have more to go wrong, I've heard of a
modern
boiler lasting only 7 years!!

If you don't know what that is, see one of my recent poasts
concerning the pigtailing of neutral and ground circuits.

What has pigtailing to do with electronic igniters?

You'd need an electrician's license to even comprehend what I
would
tell you about that.

Licenses are for pussies. I just prefer to get on with the
job.

IF I ever hire anyone (and usually I do all my own work), I
purposefully avoid anyone with any certifications, it just
means
they
charge more and are more fussy and won't do the work the way I
want
it.

Colon Burke is the idiot who said the top pin of a 3-pin plug
was
for
neutral.

Technically it is. Earth = neutral = 0 volts.

That's what that idiot KKKoloon thought. Neutral is not the same
as
Earth (aka Ground in the Great Satan).

Zero is zero.

Wrong, as always. And the neutral isnt always zero.

Compared to 240V, it's pretty damn near enough zero.

If I connect my desk lamp to live and earth, it will function the
same.

Wrong with the safety protection.

I assume you're talking about an earthed lamp.

Stupid assumption.

Then state what you really meant.

I did in the other.

What?

Stated what I really meant.

Can't be bothered finding this "other" (post?)

Didn't need to, posted the same day. Even you should be able to find it.

So I've now got my lamp's casing connected to 0V instead of 0V. I'm
sure my finger won't be able to tell the difference.

It will with a fault that see the active in contact with the case.

That would be a dead short,

Not when you are actually stupid enough to cut off the earth wire.

The casing could be connected to neutral.

Not in the UK it isnt.

I said COULD.

Irrelevant to what is being discussed.

I was explaining why earth is pointless.

It isnt pointless. The earthed case is there so that if the active
comes adrift inside the device and contacts the case, that takes
out the fuse or burns out the whisker of active wire. Without
that the case is at 240V and touching the case and another earth
like the kitchen sink or a concrete floor can electrocute you.
And it stays dangerous with no warning at all until that happens.

And you didn't explain anything, you flaunted your ignorance.

blowing the fuse before I had a chance to touch the lamp.

Wrong, as always.

Just like a fuse currently blows by a short to earth.

Not when you stupidly cut off all the earths.
