Abstract: A system for detecting and preventing electrical fire includes an intake fuse box, a main distribution panel/housing, a subdistribution panel/housing, a main power circuit (MPC) connecting the intake fuse box (IFB) to the main distribution panel (MDP), and a sub power circuit (SPC) connecting the MDP to the subdistribution panel. First-third gas/smoke/heat detectors are arranged in the IFB, main panel housing, and subpanel housing, respectively, and provide respective low level outputs for gas/smoke/heat exceeding a first threshold and high level outputs for a second threshold. A remote controlled main level circuit breaker is arranged in the MPC, a remote controlled sub level circuit breaker is arranged in the SPC, and a controller unit has first-third inputs connected to first-third gas/smoke/heat detectors, respectively, for receiving first-third low and high level outputs, an alarm output, and first and second breaker control outputs connected to respective main and sub level circuit breakers.

Abstract: A system for detecting and preventing an electrical fire in a domestic electricity distribution system comprising an intake fuse box, a main distribution panel comprised in a main panel housing, a subdistribution panel comprised in a subpanel housing, a main power circuit connecting the intake fuse box to the main distribution panel, and a sub power circuit connecting the main distribution panel to the subdistribution panel. First, second and third gas, smoke and heat detectors are arranged in respective ones of said intake fuse box, said main panel housing, and said subpanel housing, and being adapted to provide respective first, second and third low level outputs if subjected to a gas, smoke or heat exceeding a first threshold and to provide respective first, second and third high level outputs if subjected to a gas, smoke or heat exceeding a second threshold.
