Those panels are fire hazards and the REA IMO is not doing due diligence by not addressing that panel.
Here is what goes in my reports when I see these types of fires waiting to happen.
A Federal Pacific Electric “Stab-Lok” service panel was in use. These panels and breakers are a latent hazard and can fail to trip in response to over current, 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.
On a side note, the breaker in question is probably the safest part of that whole set up.
