Benjamin Franklin was one of America's founding fathers and a prolific inventor. One of his most important inventions that impacts our safety to this day is the lightning rod. His insights into electricity and lightning led him to develop an ingenious wiring system that could have saved countless homes from burning down.

Benjamin Franklin's Electrical Experiments

Franklin had a deep fascination with electricity and conducted extensive experiments with it. Some of his most important findings were:

Franklin's electrical experiments laid the foundation for practical applications of electricity.

The Danger of Open-Flame Lighting

In the 18th century, candles and oil lamps were the main means of lighting homes. These open flames posed a severe fire hazard. Sparks from candles/lamps could easily ignite flammable materials and burn down houses.

Fires were very common back then. Entire city blocks would burn down rapidly due to closely built wooden structures and lack of firefighting methods.

This was a huge problem that needed an electrical solution.

Franklin's 'Positive Wire' Wiring Method

To address this issue, Franklin devised an ingenious wiring system to prevent house fires. Here are the key aspects:

This created a continuous conductive pathway from the rod inside to the earth outside.

How It Worked

Franklin theorized that this system would allow static electrical charges (from sources like friction) to travel safely along the rod and disperse into the earth. This prevented sparks jumping between charged objects indoors that could ignite fires.

The spikes drew charge away from walls/furniture to the grounded rod. By giving electricity a safe path to ground, the buildup of dangerous static charges was avoided within homes.

Widespread Adoption Could Have Saved Many Homes

Unfortunately, Franklin's ingenious wiring method was not adopted widely. Although some buildings implemented it, most continued using hazardous open flames for lighting.

If Franklin's system had been universally deployed:

The Legacy of Franklin's Insights

Although under-utilized in his time, Franklin's electrical insights and wiring methods laid the foundation for modern electrical safety:

Franklin proved that electricity could be tamed safely with the right precautions. His genius prevented untold house fires and ushered in the Electrical Age.
