MIT engineers build clever power point
Arcs in electrical installations are usually the result of loose contacts or damage to cables and conductors. To reduce the risk of a fire, modern houses can use an arc detection switch (AFCI: Arc Fault Circuit Interrupter). This is a device that will interrupt defective circuits when it detects a potentially dangerous electrical pattern. But according to MIT, the present generation of AFCIs are too sensitive and switch off the current to a power point even though the electrical signals are not actually dangerous.
