That was exactly the trouble we had - far to many electrical devices,
with leaky filters on the power supply input. It would work fine for
weeks and then randomly trip once in a while. Solved by splitting the
leakage, by ditching the RCD and changing out all the MCBs for RCBOs
instead.

In the end that is all you can do. Ditch the whole premises RCD and
individually make rings protected.

Whole-house RCDs are a right pain. At our previous house we had one spur
that ran to an outhouse. If there was a storm, the house RCD would trip
if the spur\'s MCB was turned on, but would not if the spur was turned
off. After losing a freezer full of food because the whole house had
tripped, we got into the habit of turning off the \"outside\" MCB whenever
we were not using it - and especially if we were going away on holiday.

If each ring main or spur had had a separate RCD, only that circuit
would have tripped if there was an apparent earth leakage problem.

But I imagine RCDs are expensive and MCBs are cheap, so circuits are
protected only by over-current, and then the whole house is protected by
earth-leakage RCD.


Apart from cost, is there any disadvantage in dispensing with
over-current MCBs altogether, and protecting each circuit with its own
over-current/earth-leakage combined circuit breaker so as to confine the
power-loss to the smallest practicable set of appliances?

Is that going to happen tho given the way you lot are so keen on ring
mains ?

911 can be a problem on a PBX with \"dial 9 for an outside line\". People
dial 9, then 1 to start a Long Distance call, somehow hit a second 1 and
there you go

Also police get \"butt-dialed\" 911 calls all the time from users who
don\'t lock their keypads

That\'s an accurate butt. I can see 999, but not 911.

Back when we used mobile phones with buttons on the front, my company
phone allowed you to lock the keypad by pressing * and # together

Mine was like that, those keys were easily pressed if it was in my pocket and I leaned against a desk. Then whoever was first on the contacts list got dialled by leaning on the 1 I think. I often had a friend shouting at me from my pocket.

- but some complete idiot decided that having the phone locked and unable to
dial 999 was a safety risk, so holding 9 caused it to call the emergency
services ... and sitting and keeping the 9 pressed was far more likely
than dialling 999 and pressing green, while it was in your pocket!

Same twat that thought it was a good idea to let someone else use my phone to dial an emergency number. Well fuck them, my lock screen doesn\'t have that option now. I changed it.

Why, is she asymmetrical?

As a young child, I would just pretend to write.

I\'ve never understood people who get left and right confused. I can

Two friends of mine took part in a driving challenge, part of which
involved driving a course blindfolded, with the passenger giving
directions. They had to resort to \"your side\" and \"my side\".

I hate it when a garage says \"your offside front tyre needs changing\".
What?!? Now I have to picture a car parked on the side of the road
you\'d drive on, and work out which side would be furthest from the

When I say this, I often get the monumentally stupid response \"but are

Yes, and then every maker of business phone exchanges also decided to
then use \"9\" to begin the dial sequence of an outside line.

Many years ago, we used to have 4-digit office extensions; 1nnn

From the rest of the UK, they could dial direct to an extension on 061
902 1nnn (061 being the Manchester area code and 902 being the local
exchange).

In the 061 area, just dialling 902 1nnn worked.

One guy left, but his desk phone regularly rang. The company had a
policy of someone answering any phone within 3 rings, but we just
ignored that phone.

One day a manager was passing as I ignored the phone and questioned me
about not answering. I said it\'s for the NatWest bank. The manager
looked at me oddly, picked up the phone and yes, it was a call for a
branch of the NatWest Bank in Birmingham. He then looked at me even more
oddly.

People all over the 061 area dialled a 9 for an outside line, when they
didn\'t need to, then 021 for Birmingham and then nnn nnnn, effectively
dialing the local number 902 1xxx, plus some extra, ignored digits

Why didn\'t you unplug the phone? Or change the number on your phone
exchange?

Couple that stupid choice with \"dial 1 for long distance\" and every long
distance call begins as \"9 1\" -- two thirds of the 911 emergency
number.

I\'ve known folks who accidentally dialed an additional \"1\" after the
\"long distance + outside line\" prefix and had to explain that no, they
really were not trying to contact emergency services.

Even worse were some of the mobile phones with buttons. With mine,
pressing * and # together locked the keypad to prevent accidental (butt)
dialling in your pocket - except that some bright spark had decided that
to make emergency calls easier, pressing and holding the 9 key would
call the emergency number, even when locked ... which of course was even
more likely to happen than if you left the keypad unlocked and randomly
dialled numbers!

My smartphone allows (as I think they all do) anyone to dial an
emergency number without unlocking the phone. I\'ve denied them that
priveledge by replacing the standard lock screen. If you want to phone
the emergency services, use your own fucking phone.

What if you are dying, and the person near you doesn\'t have a phone and
yours doesn\'t work because you blocked it?

You will deserve what happens next.

Very unlikely for all those things to happen at once. I didn\'t get vaccinated either, I never wear a seatbelt, and I never enter the lottery. Remote chances don\'t interest me.

I don\'t know about butt dials, but we had a fax machine that needed to dial a 9 for an outside line. I think the long distance 1 was being typed into the phone number, but also added by the machine. You can see what happened there! After just two calls to 911, the fax machine was unplugged.

No, they are for different tellies. Because there are so many muxes and
frequencies that its so unlikley that you will want to view two
programs on the same mux, that each port on the wall into which a telly
plugs has its own LNB.

Charlton\'s scrapyard. Whilst going about that we noticed the number of
cars that had very bent steering wheels, this i was told was because
the drivers having hit most anything their body flew forward and their
chest impacted the wheel and bent it, and no way could we bend it back.

Ron\'s old boy there said that most all the drivers in that sort of
impact didn\'t survive

Then came a seatbelt\'s and that became a thing of the past once people
started using them and we got round the stupidity of \"its better to be

Sort of. The important factor is tractive effort; but horsepower was a
known factor as well.

Indeed. From Audel\'s volume 1:

\"Horse Power - This unit was introduced by James Watt to measure the
power of his steam engines; defined as 33,000 ft. lbs. per minute.\"
Audels Engineers and Mechanics Guide Vol 1. pg 78.

A farmer told me he had horses that could exceed that.

How annoying. The British fuses you could stick any in any socket, and
you could put any fusewire in each too. My house, I put in what I want.

(I have one like this, got it 2nd hand). It takes fuses or breakers, no
covers, just have to be careful inserting them. And no I never turn off
the whole bloody thing just to change one fuse.
Can\'t find a picture of the actual fuses seperate.

I was always surprised that all the fuse-wire holders in a UK fuse box were
interchangeable - there was nothing to stop you inserting a 15 A
lighting-circuit fuse in the slot for a 30 A ring-main. Everything would be
fine until someone turned on both a kettle and and electric fire on the same
ring main (thereby drawing more than 13A) and the 15 A fuse would blow.

It would have been better if the fuse holders had been designed to have
different size pins to avoid this. Of course there would still be nothing to
stop someone wiring 30 A wire into a 15 A holder, but that is (probably)
less likely than someone pulling out several fuses and then putting them
back in the wrong locations. At least the fuse holders and sockets in the
fuse box were colour-coded with domino spots which had to match.

The US screw type fuses, basically a light bulb socket, were
interchangable. Older houses around here still have them. One only
needs to keep a stock of 30 amp spares around.

So you could use a lightbulb as a fuse?
