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
profit
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 could be
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.

Nope.

Earth = neutral = 0 volts.

Nope. There are 3 pins for a reason, stupid.

Funny how the devices all work with the top one disconnected.

Because it's a safety device which doesn't get used until something
fails.

It's joined directly to neutral in my house, by the electricity board,
just next to the meter.

And that connection never fails ? Yeah, right.

Imagine a house without the earth system. Every appliance has two pins
and nothing gets a grounded chassis.

Pity about the metal plumbing etc.

All plastic nowadays,

Bull**** with the taps.

and not much of it anyway.

The sink alone is enough to kill you.

Also bathroom stuff tends to be pot.

Try that again in english, even chrome doesn't do gobbledegook yet.

Two wires come into the house, 240V and 0V. The 0V comes undone at the
meter. Everything stops functioning, no complete circuit, no power to
the lights etc. How would I accidentally give myself a shock in this
circumstance?

By being in contact with the metal plumbing or the sink
its attached to and the 240V from a frayed cord or the
240V wire coming adrift inside the appliance and in
contact with the case that you are too stupid to earth.

So you want the neutral to come undone, AND a frayed cord to appear at the
same time?

Nope.

Do you realise how low the chances of that are?

Having fun thrashing that straw man ?

With the case not earthed, all it takes is for the active
to come off and contact the case and you have 240V
between the case and sink and that can certainly kill you.
