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

I used to pause with that one but it has just dawned on me that I never do anymore for some reason.

I never have to think about that one.

Weird. I did realise that some can do surprisingly well, but didnt realise that they could do that.

Me neither.

Never noticed one doing anything like that.

Yes there was (is, I still use them). The plastic slot covering the socket contacts, to stop you sticking your finger in there, has different sized holes for different amperages. Of course you can put any fusewire you wish into the cartridge. I see no point in trying to prevent people using the wrong fuse. Anything can be got around if you want to.

Oh, you think it's dangerous to have a smaller fuse? Well it isn't. The socket I mentioned above limits the size you can plug in.

Sounds fun.

A local lad went on trial for making a rude 999 call. The court case lasted 3 hours, listening to the 3 hour phone conversation. Could the worker not have just hung up? FFS. I don't know if he was charged or not.

I get irritated when I see a lack of cooperation. Two flats each with a satellite dish a metre apart. Senseless. You can get multi-LNBs to go on the end of the arm.

ROFL, you "newsreader" wraps single words, or in this case a URL. Here, this is the correct way to do it:

Anything communal is complicated. Whose job is it to fix it if it goes wrong? What if one person short circuits it, or one says it's OK and the other says it isn't? Usually all right if there is a management company for the block.

Cars aren't sentient, so they have no notion of orientation. Say port and starboard.

One can only hope.

I imagine their web site is hosted on Amazon's cloud server.

It must be terrible to be trapped inside your head. There is so much fun and beautiful and tasty stuff in our world, and only one lifetime to enjoy them.

There's a cold front moving in and the sun is rising over the bay. What a beautiful planet.

Learn some electronics and stop being so downer. All that anger will kill you and make you miserable meanwhile. The first thing you need to design is yourself.

I'm thinking about a new product line of small boxes that use Raspberry Pi Pico and PoE. There are some cool little PoE power supply boards that sell for a fraction of what I could buy parts for.

Basically, buy boards and use them as components, sort of hardware abstraction. How does that sound?

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.

There are two types of screw fuses, "T" and "S".

"A type T fuse looks a lot like a lightbulb and screws into the sockets of old fuse boxes. Conversely, the type S fuse requires an adapter base to work with Edison type sockets. Type S fuses are designed to be tamperproof. They help homeowners not accidentally use the wrong fuse for their circuits.

A type S fuse has an adapter base with a unique size and thread so you don\u2019t mismatch the fuses. In other words, the size and thread of the base prevent you from putting a 15-amp fuse in a 20-amp circuit. However, a type T fuse will work with any Edison socket irrespective of the amperage of the circuit. If your home has an old fuse box that uses Edison sockets, talk to the technicians at [company_name] about making the switch to socket adapters that use S fuses. This can make your panel a lot safer.

Why do any offices require this? Ours didn't. If you dialled 4 digits you got an internal line. If you dialled anything else it went externally. I programmed it that way, but I'm sure pre-digital office exchanges could be made to do the same. Starting with a 0 would be the first clue.

I'm an electrical engineer, so I can make my own judgements. I talk to electricians and few if any actually understand basic electrical principles. I have read the local electric codes but never met an electrician who has.

Most houses around here have breakers now.

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.

Oh, I stopped using the tongue test when I got my first multimeter. Maybe earlier, I had a car voltmeter/ammeter. I wonder where it is now.

heh.
