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.

“Whom the gods love, die young.”
Menander (341-290 BCE)

“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.”

Legacy | Toledo Ohio

“Everybody knows how to raise children, except the people who have them.”

“America wasn’t founded so that we could all be better. America was founded so we could all be anything we damned well pleased.”

“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.”

Rolling Stone

“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.”

“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.

Hospital Plug Load

Today we examine relatively recent transactions in electrotechnologies — power, information and communication technology — that are present (and usually required) in patient care settings.   At a patient’s bedside in a hospital or healthcare setting, various electrical loads or devices may be present to provide medical care, monitoring, and comfort. Some of the common electrical loads found at a patient’s bedside include:

Hospital Bed: Electric hospital beds allow for adjustments in height, head position, and leg position to provide patient comfort and facilitate medical procedures.

Patient Monitor: These monitors display vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate, helping healthcare professionals keep track of the patient’s condition.

Infusion Pumps: These devices administer medications, fluids, and nutrients intravenously at a controlled rate.

Ventilators: Mechanical ventilators provide respiratory support to patients who have difficulty breathing on their own.

Pulse Oximeter: This non-invasive device measures the oxygen saturation level in the patient’s blood.

Electrocardiogram (ECG/EKG) Machine: It records the electrical activity of the heart and is used to diagnose cardiac conditions.

Enteral Feeding Pump: Used to deliver liquid nutrition to patients who cannot take food by mouth.

Suction Machine: It assists in removing secretions from the patient’s airway.

IV Poles: To hold and support intravenous fluid bags and tubing.

Warming Devices: Devices like warming blankets or warm air blowers are used to maintain the patient’s body temperature during surgery or recovery.

Patient Call Button: A simple push-button that allows patients to call for assistance from the nursing staff.

Overbed Tables: A movable table that allows patients to eat, read, or use personal items comfortably.

Reading Lights: Bedside lights that allow patients to read or perform tasks without disturbing others.

Television and Entertainment Devices: To provide entertainment and alleviate boredom during the patient’s stay.

Charging Outlets: Electrical outlets to charge personal electronic devices like smartphones, tablets, and laptops.

It’s important to note that the specific devices and equipment present at a patient’s bedside may vary depending on the level of care required and the hospital’s equipment standards. Additionally, strict safety measures and electrical grounding are essential to ensure patient safety when using electrical devices in a healthcare setting.  

We have been tracking the back-and-forth on proposals, considerations, adoption and rejections in the 3-year revision cycles of the 2023 National Electrical Code and the2021 Healthcare Facilities Code.  We will use the documents linked below as a starting point for discussion; and possible action:

“Le Coin de Cuisine” | 1883 Edwin Deakin

Education communities are stewards of hundreds of commercial-class kitchens in which the proximate risk of electrical energy must be managed — water spills and grease, fires, worn electrical cords on countertop equipment, faulty wiring or equipment, damaged outlets or connectors, and improperly used or damaged extension cords among them.   The safety and sustainability rules for this occupancy class is identified as Assembly Group A-2 in Section 303 of the International Building Code

We explore recent transcripts of expert committee activity in NEC Article 210 and provide links to video commentary.

Public comment on the Second Draft of the 2026 NEC will be received until April 18.  We typically coordinate our effort with the IEEE Education & Healthcare Facilities Committee.  The workspace set up for generating proposals can be found in the link below.
