I’ve been helping a friend with some remodel work and noticed some service panels. Today I needed to pull the covers- My suspicions were confirmed
Top panels are zinscos and the lower 50 amp disconnect is a FPE
The FPE was a suprise, but the tag on the inside clearly states that it is a stab-lock type.
Had to read the zinsco labels carefully since the zinsco name only occurs once when it tells the consumer to only use zinsco breakers.
I hated the fact I had to tell him the bad news, but thought it would be better if he knew about the electrical panels in his house.
