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

From your own link, zero, yet they still make a fuss. "no electrocution has been traced back to a failed death cap "

Move to the UK, where we have the sense to understand the difference between live and neutral.

Only if you have a heart condition. How unfit are those singers?

And puts up with noise?

And you're still alive, what does this tell you?

My father always said "stylus", which he seemed to think was much better than a "needle".

My first language is not English: I had to seek for a word I am not used to using :-)

The city electrical code.

New construction and repairs require permits and inspection.

Some things like commercial buildings get annual inspections, mostly for fire safety.

I can elect to take risks if I want to. A non-GFD outlet 9 feet away from a faucet doesn't seem very risky to me.

You can be tribal and snarky if you want to.

Hum, the volume spindle would be live.

I must remember to grab one of my old radios from storage and test. I knew, but I have forgotten.

I'm curious. How?

The only Meccano motor I had came with no transformer, so I used batteries or my own transformer, which was safe. Never shocked me.

Some countries have an inspection before electricity is provided for the first time.

Some countries have periodical inspections.

Also, if there is an incident, like a fire, or an electrocution, the insurance people can refuse to pay if there is no RCS.

The same way a car ignition coil generates 200V on its primary and 25kV on its secondary. Inductive flyback.

12v battery can give you a hell of a shock connected to an ignition coil cant it?

Think you need to revisit electrical circuits 101....

That "natural" could be only because that's what you're familiar with.

I know someone who can't tell left from right without touching herself.

Interesting that you felt a need to say both. If one way is on, you should already know what the other way is.

Stylus was the new word, starting in the 1960's iirc. The original word was needle, and they looked like needles, steel pins with a point, about an inch long. Held in place with a finger screw. . I still have my mother's 78 rpm record player, probably from the 20's, and a couple boxes labeled "needles" "Guaranteed to play 10 records". I think it also says "genuine steel".

I couldn't really see the difference between a used needle and a new one, and I hope I didn't damage any of the records.

Her record player doesn't have speakers, not even one, or any controls except on/off. For sound you have to turn on a nearby AM radio and tune to the right frequency. I meant to check if that means I can listen all over the house, which would be really nice, but until just now, I'd forgotten about

Didn't find her brand but this is similar:

Etsy.com also has old needles. I thought it just sold new stuff to make crafts, or newly made crafts.

Ah, of course :-)

One of the things I had as a kid was a physics set made by Kosmos. Or an electricity one, I forget which had this experiment. Well, one of the experiments was to build an electric bell, running off a 4.5 battery. And then, a second experiment was to hold both electrodes in my hands.

Shock.

They said they made electric fences for cattle that way, but that it was safe. It wasn't a massive shock, just a shock :-)

I had forgotten that experiment. Never got that shock with a motor, though. Maybe my motors were smaller :-?

Sure does. It is also a massive coil, designed for that.

:-D

I actually have seen those. I have an electric gramophone somewhere. Or did I give it to someone?

:-D

They do, new or not. Lots of weight in the arm.

No, that's not how they worked.

Radios of that era had a setting named "phone". And a socket. You connected the output of the "electric gramophone" pickup to the phone input of the radio, which was actually the audio amplifier section.

The radio could have a switch to disable the radio section or not, in which case you would have to "tune out" the stations.

That's for sure. In fact it's lifting the arm off of its support that turns the steel turntable on. Arm weighs maybe 1/2 to 3/4 pound? Just guessing, but it's steel too.

Not like you to think you know more about my phonograph than I do.

Mine has no output jacks or cords. Just a small nice wooden cabinet with no holes, no jacks, maybe one 12" wire as a transmitting antenna (I have to go look again. Not sure if there's a wire.)

Maybe 14 or 16" square and 5" high.

It might be from the 30's after my mother got married in 1929.

I have been lucky enough that there was no strong station at the frequency. I left a note inside so I or the next owner doesn't have to hunt for it.

Why bother with the cap? Just connect all neutrals and the stage together and to ground. In my house neutral and ground are identical anyway, there's only a two core cable supplying the house. Earths and neutrals from all sockets go to the 0V wire, all lives go the 240V wire. Simple.

I doubt that's ever happened. Something falls precisely against it and it happens to be off?

Then why do I remember seeing a blue light?

Why do you misuse the word code? A code is some kind of encryption. You mean regulation. If Americans are to integrate with society, they need to learn to speak English correctly.

And not stalled. Essentially a stalled motor is a damn great inductor.

One of these...
