Today at 15:00 UTC we review the very considerable work we have undertaken for the better part of thirty years on NFPA and IEEE best practice literature that governs the safety of proximate electrical energy devices. Use the login credentials at the upper right of our home page.
The primary differences between United States and European electric receptacles stem from voltage, frequency, plug design, and standards. In the U.S., the standard voltage is 120 volts, operating at a frequency of 60 Hz. European countries typically use 230 volts at 50 Hz. This voltage disparity means devices designed for one system may not function properly—or safely—in the other without adapters or converters.
Plug design also varies significantly. U.S. receptacles use Type A or B plugs, featuring two flat pins (Type A) or two flat pins plus a round grounding pin (Type B). European receptacles commonly use Type C, E, or F plugs under the CEE 7 standard. Type C has two round pins, while Type E and F include grounding pins—E with a pin protruding from the socket, and F with side grounding clips. These physical differences make plugs incompatible between regions without adapters.
Wiring and safety standards further distinguish the systems. U.S. outlets follow the National Electrical Code (NEC), while Europe adheres to the International Electrotechnical Commission (IEC) standards. Grounding and polarization requirements also differ, reflecting regional engineering practices. Ultimately, these distinctions ensure safety and efficiency but complicate international device compatibility.

“My mother was a Protestant, of a traditional American, vague kind: she belonged to the church that the nice people in the neighbourhood went to. My wife is a Catholic, the kids are Catholic, so I’m a Catholic fellow-traveller.”

“Giving money and power to government is like giving whiskey and car keys to teenage boys.”
“It’s better to spend money like there’s no tomorrow than to spend tonight like there’s no money.”
“When buying and selling are controlled by legislation, the first things to be bought and sold are legislators.”
“If government were a product, selling it would be illegal.”
“The Democrats are the party that says government will make you smarter, taller, richer, and remove the crabgrass on your lawn. The Republicans are the party that says government doesn’t work and then they get elected and prove it.”
“Not much was really invented during the Renaissance, if you don’t count modern civilization.”
“No humorist is under any obligation to provide answers and probably if you were to delve into the literary history of humour it’s probably all about not providing answers because the humorist essentially says: this is the way things are.”
Standards for a Kitchen Symphony | November/December 2024
ASTM International (formerly known as the American Society for Testing and Materials) is a globally recognized organization that develops and publishes technical standards for a wide range of products, systems, and services. These standards are used by manufacturers, regulatory bodies, and other stakeholders to ensure that products and services are safe, reliable, and of high quality.
In the field of measurement science, ASTM plays an important role in developing standards and guidelines for measurement techniques and practices. These standards cover a wide range of topics related to measurement science, including the calibration of instruments, the characterization of measurement systems, and the validation of measurement results. They are used by researchers, engineers, and other professionals in academia, industry, and government to ensure that measurements are accurate, precise, and reliable.
ANSI Public Review |
ASTM standards for measurement science are developed through a process that involves input from experts in the field, including researchers, industry professionals, and regulatory bodies. These standards are updated regularly to reflect advances in measurement science and technology, as well as changes in industry and regulatory requirements. This is a far better way to discover and promulgate leading practice. In fact, there are regulations intended to restrain the outsized influence of vertical incumbents in legislative precincts where market-making happens.

“G.K. Chesterton’s Fence” is a concept often cited in discussions about change, reform, and tradition — in software as well as in “campus traditions”.
It’s derived from a quote by the English writer, G.K. Chesterton, which goes: “In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, ‘I don’t see the use of this; let us clear it away.’ To which the more intelligent type of reformer will do well to answer: ‘If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.'”
In essence, Chesterton is cautioning against the impulse to dismantle or alter established systems, institutions, or traditions without fully understanding why they were put in place in the first instance. The “fence” represents any existing structure, rule, or tradition, while the act of removing it symbolizes reform or change. Chesterton suggests that before advocating for the removal or alteration of something, one should first understand its purpose and history. This is because such structures often have reasons for their existence, which might not be immediately apparent to those seeking change.
The principle emphasizes the importance of respecting tradition and the wisdom of those who came before, as well as the necessity of informed decision-making when it comes to implementing reforms. It urges individuals to exercise caution and humility, recognizing that existing systems may have evolved to address specific needs or challenges, and that blindly discarding them could lead to unforeseen consequences.
