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

If you were an old buffer you could recall that port is always passed to the left.

I'm right handed, and my "official" favourite colour is green, which gives me the colour of the lights (which I never need).

Actually, for port and starboard you could use the etymology: "starboard" was originally "steerboard": the wide oar used to steer boats before proper rudders. This was on the right as most men (and hence steersmen) were right handed.

English didn't have a word for orange until the fruit was imported. Orange things were just described as red; hence "robin redbreast" which clearly has an orange breast.

Why would the centre tap have anything to do with them going in the same direction?

No, installing them with up as on is what's annoying, since down should be on, so you think they're off when they're on. Asking for an electrocution when someone's working on something.

No idea what century he's living in, we don't use pipes to provide earth, we use a 100A cable to the f****ng great big ground spike at the substation.

"Have to"? You don't have to do anything. You have a perfectly good ground in the wire, why make your own less effective one?

WTF is a house fan? Kitchen extractor? Ceiling fan?

There is no reason, unless you think the blades must rotate in a particular direction for some reason.

So I'm in danger of getting a 2 volt electric shock?!

Why would lights be these days and not other things?

There is no requirement to have ANY breakers, I have fuses.

And you'll sleep more soundly knowing you're being a double pansy.

They operate by spring, so of course they work like that. Sometimes you have to use common sense.

WTF is a service disconnect?

America is backward and always has been. Do you read from the bottom of the page to the top? Maybe top posters originated in America.

Why rotate them just because you have more phases?

Then why turn it sideways? Have you done that with your TV too? Up and down are easier to remember than left and right.

I doubt glass bounces screws anymore than wood.

I'll tell you what really bounces, a memory foam mattress. I found that out when chucking my camera onto it. It bounced onto the wooden floor and busted the battery cover.

Are Americans very weak? It's 30-50mA here. You need 80mA to stop a human heart. 5 would be a stupidly sensitive breaker.

So much easier without an ELCB. No, I will not call it an RCD. Earth leakage circuit breaker, does what it says on the tin. It's nothing to do with a residual anything. Current doesn't hang about like a residue.

I bet they cost a fortune. Fusewire is a fraction of a penny.

Sure, but the Japs always had green grass and green vegys.

Uh.... why would you need to use the keypad with your dominant hand? Both hands are used to type.

Of course, being "right handed" I'm actually ambidextrous like the majority of the population. Maybe lefties are different.

Rotary took f****ng ages to dial long distance. And a very long time to dial the UK emergency 999. Should have been 111.

It does...

Nothing is ever designed sensibly. Designers are arty farty people without brains.
