Then it's a damn good thing you don't do electrical work in the US, isn't it? What you can't see is that there are grooved slots in the terminal that grip the wire, when the screw is tightened. 'Crimps' are illegal, without certified tools with current inspection tags & proper training. They are used in the few places with aluminum wire, to crip a copper pigtail onto the aluminum wire, and every part of the process is tightly controlled. Either hire the right work, or rewire the building with copper.

I didn't say the hotel wasn't open to the public, it might have been open for a century or more. I did say that it -i.e. dis boxes and cables

- looked fairly new. and that`s not a cable tray at the top, it looks like two strips of plywood. I imagine that there should/will be some kind of box around it. That's probably the dis-board for the whole floor. I'm sure that it should be safely under lock and key if it's in a public room

Who knows...

Somewhat, but this is a typical example, with a warming tray on top. The tray uses the waste heat from the oven.

A lot are just a small oven with temperature and timer controls. There are also counter top pizza ovens. :)

Sigh. Such arrogant ignorance. You've never seen one, or used on, but all you can do is find fault with them. There are millions of homes and businesses using them 24/7 and you rarely have a problem unless someone smashes one, or uses a damaged plug in one. The earlier type had a shroud where the wire couldn't 'spew'. the screw had a grove under the head to lull the wire tighter as it compressed the wire and held a lot tighter than any crimp terminal.

The newer style has a groove with serration that goes through a hole and is clamped between the screw head and the terminal. You strip 1/2" insulation, shove it in till it bottoms out and tighten the screw. They will not come loose, unless a total fool installs it.

My point was that the lights were on. That isn't the case, prior to inspection and getting a Certificate of Ocupancy in the US. If a US building needed a major rewire like that it would be close until the work was complete, and had all the paperwork is in order.

It is. I'd not be able to warrant my work with bodges like that.

Makes little difference. The *only* reason to use that sort of connection is cost - and that fitting certainly looks cheap.

Goes without saying that any crimp must be made with the correct tool. But of course an additional connection is a bad thing except where essential. And I'd say it was essential with those fittings.

Aluminium cable was tried here briefly many years ago - but I've never come across it. Only used by those who put money before safety and longevity.

Oh, but *I* have. Did some work on an American Optical installation that used these some time ago - and just assumed the design had been changed for something better by now.

In those days having electricty was a big deal. It showed you were prosperous and could afford the price of wiring, the cost of the things to run and the cost of running them.

As part of the plan to recover from "the great depression", the US built several large hydroelectric generating stations (and impressive dams to provide the water), ran lots of lines and "electrified" most of rural America (USA).

No one can say you aren't opinionated. Or right.

They also allowed outdated factories to change from water wheels driving overhead shafts, and whale oil lights. Electricity on farms improved efficiency and safety.

Why change it? They have a damn good safety record, and there are over a billion in use. Just because someone outside the US dislikes them is no reason to change. There are multiple grades, from what I linked, to medical grade with extreme low leakage. There are commercial grade, intended for heavy usage. Think about it. Most plugs are rarely inserted or removed, and the standard duty is fine. Some items are only plugged in one time, and used till the item is worn out. From what I've seen of European connectors, I wouldn't use one anywhere. We had to use them in the Earth Stations we built for the European Space Agency. We had them ship us what they wanted used, then had to fight with it to find enough usable hardware. The outlets we used on US turnkey were steel Wiremold outlet strips. They sent us pairs of sockets that had to be wired and mounted inside the racks. It looked like the crap imported from China for flea markets. No inspect for US use, and the connectors are incompatible with the US market. Some had a tiny expanded scale 250 voltmeter that displayed 200 to 250 volts. They wondered why only foreign tourist were buying the crap.

I was thinking that some business would do the importing and take care of the UL approvals. Seems like there is quite a bit of margin to work with.

A toaster oven has no hot plates. It is just an oven and has no stove elements.

Most of that happened down south and is called the TVA (Tennessee Valley Authority). The TVA turned out to be a very strategic resource - it provided massive amounts of power to the Oak Ridge uranium refining facility.

The Hoover Dam in Nevada and the Grand Coulee dam in Washington state were also built at about the same time. The Grand Coulee Dam provided massive amounts of electric power to the Hanford plutonium refining facility.

There is also an internal terminal that clamps the wire from both sides.

I have to admit that I've disassembled a lot of 30-80 year old screw terminals of the kind you decry, and they are still very solid. Generally, there is a strip of very clean copper where the screw head and terminal plate met the bare wire. I think that the large gauge wire and relatively immobile wiring has something to do with it.

It would also take a lot of liability insurance. By the time you pay shipping, duty, and all other overhead expenses most if not all of that profit is long gone.

That is because you use them as an add-on facility whilst the Baby Belling is designed as a lone unit, primarily for student bed sits, small flats, etc., that don't have room for a full size cooker. I have seen them in the staff refreshment area of small businesses, although it would be more common to find a microwave these days.

If you took away the hot plates on the Belling you would end up with something similar. In the UK, though, though tend to used as the only means of cooking when space is very limited - thus the hot plate facilities are required.

If the Tea Party had been running the country back then, these "socialist" projects would never have happened.

And Ron Paul supporters are all for closing down the TVA.

One wonders if these people ever think about the consequences of what they are demanding ...
