Biscuits and sausage gravy is firmly rooted in Southern American cuisine, which has a rich history influenced by African, Native American, European, and other culinary traditions. The combination of biscuits and sausage gravy reflects the availability of ingredients in the South, where biscuits (similar to a type of British scone) and pork products were common.
The concept of biscuits, similar to what Americans call biscuits, has British origins. Early settlers brought this baking technique with them to the American colonies. However, the American biscuit evolved over time to become lighter and fluffier compared to the denser British biscuit.

Today at the usual hour we review best practice literature for the design, construction and operation of Power-Limited Circuits in healthcare facilities. With our previous tenure on Code Panel 15 of the National Electrical Code (which covers healthcare facilities, primarily) and our recent appointment by IEEE to Code Panel 3 (which covers power limited circuits in all occupancy classes) we set ourselves up to respond to the proposals that will shape the 2029 NEC.

If one imagines that three-phase hospital power distribution systems as “arteries” then power limited circuits can be imagined as the “capillaries” that drive hundreds of end use clinical equipment and devices. The analogy captures the hierarchical, physiological structure of hospital electrical systems—much like the human circulatory system—where power flows from high-capacity trunks to precision, low-risk endpoints.
Three-Phase Systems: The Arteries and Veins
Three-phase hospital power distribution systems function as the arteries and veins: they are the robust, high-volume “vascular” network. Incoming utility power (or on-site generators) arrives as three-phase medium voltage, stepped down through transformers and switchgear into the Essential Electrical System (EES). This backbone—normal power, life-safety, critical, and equipment branches—delivers bulk kilowatts across the facility to major loads: HVAC, lighting, elevators, imaging suites, and operating-room receptacles. Like arteries, these feeders carry large currents over long distances with minimal loss; like veins, they return current safely while maintaining redundancy and selective coordination to keep the “body” (hospital) alive during outages.
Power-Limited Circuits: The Capillaries
Power-limited circuits (NEC Article 725/724 Class 2 and Class 3) are the capillaries. They are the countless, tiny, energy-restricted final branches that directly “perfuse” end-use clinical devices. These circuits are deliberately power-limited—typically ≤30 V and ≤100 VA—to prevent fire, shock, or interference in patient-care spaces. They supply nurse-call systems, bedside monitors, infusion-pump controls, alarm signaling, data links, and low-voltage sensors. Just as capillaries exchange oxygen and nutrients cell-by-cell without flooding tissue, power-limited circuits deliver only the precise, safe wattage needed by sensitive electronics while isolating them from the high-energy main distribution. Their thin insulation, separation rules, and inherent current-limiting transformers mirror the delicate walls of capillaries.
The comparison illuminates why hospitals cannot rely solely on heavy three-phase feeders: without these microscopic “capillaries,” clinical devices would either lack power or be exposed to dangerous fault energies. The analogy shows how the entire system maintains life—bulk transport for infrastructure, micro-delivery for patient care—while enforcing safety through progressive limitation. In essence, the capillaries make the circulatory system functional at the point of use.

Nitro cold brew is bubbling up in coffee shops almost everywhere. The nitrogen-infused beverage became one of the hottest new offerings for coffee lovers looking for something different. The cold brew — made by steeping coffee grinds in cold water for multiple hours — is dispensed from a stout tap, similar to what you’d find at your local bar.

Howard Zinn taught at Boston University from 1964 to 1988. His intellectual legacy has not held up well among serious historians. Zinn presented American history as a simplistic morality play of evil elites versus virtuous “the people.” Scholars across the political spectrum, including left-leaning historians like Michael Kazin and Sam Wineburg, have criticized it as a “polemic disguised as history” and a Manichean fable rather than rigorous scholarship. The book is filled with selective quoting, decontextualized facts, major omissions, and heavy reliance on secondary sources that support his Marxist-tinged narrative. Detailed critiques, such as Mary Grabar’s Debunking Howard Zinn, document numerous factual distortions regarding Columbus, the American Revolution, slavery, WWII, and more. Zinn openly rejected “disinterested scholarship” in favor of activism, producing advocacy rather than balanced analysis. While influential in activist and popular circles, its methodological flaws and lack of nuance have kept it outside mainstream academic respect.
