Got a call to a loss of kitchen counter power & encountered this beautiful early 80's edition of the Crouse Hinds overcurrent protection equiptment.... As typical, the contacts on one of the breakers had, as Electure terms it, "Zinsco-itis... or pitting of the busbar... the really nice part was when I pulled the breaker from the panel, the bus came with it! But alas, the panel was fully de-energized (Thankfully!) One subpanel change, coming up!
Zinsco-itis? That is a new one, but that affliction seem to affect any AL bussed panel BTW, I pulled a Zinsco W/ CU buss bars this weekend during "the service change from hell".
LOL Mark... Not on this day, wayyy long day before I even got to this! Rollie, The bus has oxidation on it, most wisible in the 2nd pic... I've found this specific design of breaker (where the breaker attaches to the busbar with that little tiny loop of a contact) to fail nearly as much as Zinsco & their contacts.... At least they tend to fail-safe when they fail though.... I've replaced many Crouse-Hinds 100A main breakers that tripped & just didnt want to reset!
