They do not provide the level of circuit protection required by the NEC (National Electrical Code). Homeowners should be alerted to this safety defect and advised to have it corrected. FPE Stab-Lok circuit breaker panels should be replaced unless the occupants are informed and willing to live with the resulting increased risk of fire and injury.
The National Electrical Code has been updated for 2014 to address the use of Outlet Branch Circuit (OBC) Arc Fault Circuit Interrupter (AFCI) receptacles as an alternative to traditional circuit breakers when used for modifications, extensions, replacement receptacles, or in new construction.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes. The rating of power circuit breakers varies according to the application voltage; a circuit breaker that interrupts 50,000 amperes at 208 volts might be rated to interrupt only 10,000 amperes at 600 volts, for example.
The failure of a neutral fuse would cut off power flow through the affected circuit, but the hot conductor could still remain hot relative to ground, an unexpected and potentially hazardous situation. Because of the presence of a neutral fuse, and in the event that it blew, the neutral conductor could not be relied on to remain near ground ...
