Do not buy used Federal Pacific Stab-Lok Circuit Brakers

"Federal Pacific Electric "Stab-Lok" service panels and breakers
are a latent hazard and can fail to trip in response to overcurrent, leading to electrical fires.
The breakers may also fail to shut off internally even if the toggle is switched to "off."
Some double-pole (240-Volt) FPE circuit breakers and single-pole FPE Stab-Lok circuit breakers simply do not work safely.
There are other panel-defects independent of the breaker problems, panel and panel-bus fires
and arcing failures in some equipment. The failure rates for these circuit breakers were and still are significant.
In some cases failure to trip occurs 60% of the time - a serious fire and electrical shock hazard.
Failures are documented in the CPSC study and by independent research. Additional independent testing
and research are on-going and are reported here. FPE Stab-Lok electrical panels should be replaced.
Do not simply swap in some replacement breakers."
