Merlin Gerin is a brand of circuit breaker. This type of unit is used in homes and office buildings as a way to protect electric circuit from causing damage due to short circuits or overloads.
Most homes (probably all homes) are wired in a parallel circuit (actually several parallel circuits and a few dedicated circuits) so that in the event of the failure of one device in the circuit, the rest will continue to function.
