Federal Pacific Stab Lok Electrical Panel
Federal Pacific Stab Lok brand of electrical panels and circuit breakers were manufactured between 1950 and 1980. The biggest issue with the breakers is they do not securely lock into the panel and are often loose which can lead to arcing and potentially fires. Stab Lok breakers frequently failed Underwriters Laboratory testing and were discontinued, Federal Pacific was sold to a different manufacturer.
It is widely accepted in the electrical industry that FP Stab Lok panels are no longer safe and should be replaced when found.
Stab Lok breakers can be identified by the breaker going toward the outside of the panel when in the on position versus the typical breaker going to the interior.
It is also recommended that these panels are not opened, that an electrician is called to evaluate and replace the panels.
