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.
