Thomas Edison's electric power distribution system
The electrification of homes began in the late 19th century, with a pivotal moment occurring in 1878 when Thomas Edison installed the first private electric system in his residence. This sparked a wave of electrification that spread across borders.
Thomas Edison, an American inventor and businessman, is renowned for his contributions to the field of electricity. He is often credited with being the mastermind behind the invention of the lightbulb and the establishment of the world's first electric power distribution system.
Edison's electric power distribution system, first introduced in 1882, consisted of a large central power plant with generators (called dynamos), voltage-regulating devices, copper wires connecting the plant to other buildings, and the wiring, switches, fixtures, and light bulbs within those buildings. At New York City's Pearl Street Station, Edison's team designed and built the largest dynamo up until that time, nicknamed the "Jumbo." Each Jumbo weighed about 27 tons, had a 10-foot armature shaft, and produced an output of 100 kilowatts. The power station was switched on on September 4, 1882, providing 110 volts of direct current (DC) electricity to 59 customers in lower Manhattan. The number of customers quickly grew to 508, with 10,164 lamps.
Edison's system faced competition from companies installing alternating current (AC) systems. AC power could be transmitted over long distances using thinner and cheaper wires, making it more suitable for lighting in streets, small businesses, and homes outside of large cities. Edison expressed concerns about the high voltages used in AC systems, stating that they were dangerous. He joined forces with anti-AC crusader Harold P. Brown in a propaganda campaign, even supporting the development of the electric chair to portray AC as more lethal than DC. However, AC became the standard for electricity in the U.S. due to its lower cost and ability to supply power to larger areas.
Edison's electric power distribution system marked a monumental achievement, kickstarting the widespread electrification of homes and communities worldwide. His work in electric power generation, along with his inventions such as the phonograph and motion picture camera, have had a profound impact on modern industrialised life.

Nikola Tesla's work in alternating current (AC) electricity
The electrification of homes began in the late 19th century. In 1878, Thomas Edison, the inventor of the lightbulb, installed the first private electric system in his own residence. This sparked a wave of electrification that spread across borders.
Now, let's delve into Nikola Tesla's groundbreaking work in alternating current (AC) electricity, which played a pivotal role in transforming how we harness and utilise electrical power:
Nikola Tesla (1856-1943) was a Serbian-American engineer, inventor, and futurist. He immigrated to the United States in 1884 and soon began working in the emerging field of electricity. Tesla recognised the limitations of direct current (DC) systems, which were challenging to transmit over long distances. In contrast, he championed the use of alternating current (AC), which offered greater flexibility in power transmission.
In 1885, Tesla invented the polyphase induction motor, a device that revolutionised electrical generation and marked the beginning of the Second Industrial Revolution. This invention was a crucial component of the AC system, and within just three years of his arrival in the US, Tesla had filed for seven US patents related to a complete AC system based on his induction motor. These patents included everything necessary to generate electricity using AC.
The significance of Tesla's work was recognised by George Westinghouse, a pioneer in the AC versus DC debate. Westinghouse's company, Westinghouse Electric & Manufacturing Company, licensed Tesla's polyphase induction motor and transformer designs in 1888. This deal provided Tesla with substantial financial resources and helped establish the viability of the AC system.
Tesla's AC induction motor enabled the development of a two-phase AC generating system at Niagara Falls, further cementing the importance of AC power. Additionally, Tesla worked with Westinghouse to implement AC power in Pittsburgh, helping to create an AC system to power the city's streetcars.
Beyond his work with AC electricity, Tesla also conducted experiments in wireless telegraphy and artificial lightning, showcasing his diverse contributions to the field of electrical engineering.

Electric lighting in homes
The history of electric lighting in homes is a fascinating one. Before electricity, homes were illuminated by candles and gaslights, which posed fire risks and caused poor indoor air quality. The ancient Greeks first observed static electricity, but it was in the 18th century that humans began to harness its power, with Benjamin Franklin's famous kite experiment in 1752 being a notable early development.
In the late 19th century, electricity began to illuminate homes in the United States. A pivotal moment occurred in 1878 when Thomas Edison installed the first private electric system in his residence. Edison, of course, is renowned for his work on the lightbulb, but he also established the world's first electric power distribution system, marking the beginning of widespread electrification. In 1880, Edison received a patent for an "electric lamp", and in 1882, J.P. Morgan had Edison's company wire his New York residence. By 1884, Edison's Pearl Street Station power plant was serving over 500 customers.
However, it took time for electric lighting to become commonplace in homes. In 1882, parts of Manhattan adopted electric lights, but these were mostly in commercial and public settings. It wasn't until around 1925 that half of U.S. households reported using electricity. Early electrical systems had limited capacity, requiring household members to use appliances one at a time to avoid overloading the system. Knob-and-tube wiring, the first type of electrical wiring, was standard from 1890 to 1910, and continued to be used into the 1950s.
Electricity became widely available in homes in the early 20th century, and electric lighting accounted for most of a home's energy usage in the early 1900s. The introduction of dedicated electrical circuits allowed homes to safely power multiple appliances simultaneously. Electric lighting and power have not only enhanced comfort but also reshaped communities, enabling the development of skyscrapers and suburban layouts.

Electric wiring and circuits
The history of electricity in homes is a fascinating one. In the early 19th century, homes were illuminated by candles, oil lamps, and gas lighting. The first step towards electrification came in 1878 when Thomas Edison installed the first private electric system in his residence. This sparked a wave of electrification, and by 1882, parts of Manhattan were using electric lights. However, it was not until the early 20th century that electricity became widely available in homes.
The introduction of dedicated electrical circuits allowed homes to power multiple appliances safely. Early residential electrical systems had limited capacity, and knob-and-tube wiring was the standard type of wiring installation between 1890 and 1910. This type of wiring consisted of two single wires run parallel within wall or ceiling cavities and was insulated using rubberized cloth. However, this material degraded over time, making it dangerously obsolete.
In the 1920s to 1940s, flexible armored cable offered some protection from wire damage. During the 1940s, metal conduit was introduced, enclosing multiple insulated wires in rigid metal tubes. While this provided some safety improvements, the potential for danger was still much higher than today as wires weren't grounded. It wasn't until after 1965 that grounded wires became standard, creating a safer environment for homeowners.
Today, most modern homes have circuit breakers that immediately shut off power in the event of an overload, providing additional safety. The evolution of electrical wiring and circuits has played a crucial role in making electricity an essential and integral part of daily life.
