Thomas Edison
Thomas Edison developed the idea for a circuit breaker in 1879, sketched different concepts in his scientific journals and patented the idea the same year. A circuit breaker disconnects an electrical circuitry by opening a contact when the circulating electrical current reaches levels considered unsafe for the system.
What is the first circuit breaker?
Regulators put the first circuit breakers into place following the market crash that occurred on October 19, 1987. On this day, the Dow Jones Industrial Average (DJIA) shed 508 points–falling by approximately 22.6%–in a single day.
When did they stop using fuses in houses?
