Federal Electric Stab-Lok MCBs Information

Former Community Member
Former Community Member


Hi Folks,


I am currently doing an EICR on a large site, with many old Federal Electric boards with the Stab-Lok type MCBs. I think they would have been installed circa 1980.


I have been scouring the internet and these forums in particular for manufacturers details, specifically for type 4 Federal MCBs. There have been consistent figures posted throughout but I would like to get my eyes on a datasheet, or any other information that's floating about, if it was possible that any you may still have that kind of information in your archives!

 

Apologies if this is a somewhat repetitive subject as I have seen many threads over the years asking the same details. 


Cheers,


Andrew
