I’m new to the board so my apologies in advance if I hit on a topic already discussed. I am in the process of helping a friend wire in his Spa when I discovered he had an Federal Pacific electric panel with “stab loc: type circuit breakers. I have seen many articles on the web stating that these circuit breakers fail to trip on over current conditions and are fire hazards. I’d like to solicit your opinions on Federal Pacific breakers. Are they a problem? Should my friend have them replaced?
