Why do circuit breakers go up for on and down for off?

It's really handy so you can stand on the pegs, stick your arms out, and play airplane.

My first Mtn. bike was a high end GT that I bought in the late '80s. As might be expected the components were the latest, greatest. The rear brakes were a Shimano U-brake design that fell out of favor very quickly. It had Biopace chainwheels, sort of an elliptical design that faded just as rapidly. There was a frangible derailleur hanger that was delicate and very unique. The seat tube was an odd diameter.

when someone stole it they were doing me a favor. I replaced it with a plain vanilla bike with suspension forks.

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?

No metal can stand the temperature needed to go blue (>10,000K).

So why is it sometimes green for cold? My skin is never green, as I don't photosynthesise.

The chrome on my motorbike exhaust tuned blue, but not at >10000K.

I can buy MCBs for my CU for about £3.50 or RCBOs for about £35 - although I managed to find them online for about £17 when I was changing mine.

I can't think of any. There are even additional advantages - unlike most MCBs, the RCBO isolates both live and neutral when off. The ones on mine can even remain connected, but off, for working on the circuit or for carrying out insulation resistance testing.

Yes, patients like my sister who is undergoing chemotherapy and is now in isolation, having picked up a chest infection and norovirus in hospital.

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

I had 15. Only thing they did was piss on a few monitors and delaminate them.

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

Don't be ridiculous. Cats have stereo vocal chords.

Mine couldn't locate themselves for peanuts. Maybe I shouldn't have fed them peanuts.

Most people get along with their neighbours. And aren't those 8x LNBs 8 seperate devices? Buggering one won't break the others.

They don't have to know. It's us that buys the tyres.

That's no more meaningfull.

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'm not sure why I read this idiot's posts, but sometimes he says something that is entertaining, like this. Only a true idiot would think it's a good idea to ignore things that are "remotely" likely. Seatbelts is a perfect example. So many lives have been saved by them. Some people, we might not miss so much.

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.

The multiple LNBs/transponders (or whatever) won't be for different users, they'll be for different muxes, i.e. frequencies/polarisations.

And neighbours might get on in a "Good morning, how are you" kind of way, but that doesn't mean they will realise that their system is buggering up others' reception, as that is a technical matter.

Starboard=steerboard, and most steersmen were right handed.
