I’m trying to document a date of construction for a building, which has “Federal Electric” breakers.
“Federal Electric” was one of a variety of similar brand names used for what became Stab Lok breakers.
I am aware of https://inspectapedia.com/fpe/FPE_History.php
Which goes over a number of the mergers and splits this product line has taken, but it’s sparse on the early history.
Anyone have a reference to when the Federal Electric name was retired?
