A good friend has a FPE 100 amp cabinet. Obviously the breakers are
JUNK! He lacks the $ for a new service right now. He wonders if he
could replace the 100 FBE cabinet with a 200 amp new service but
install for now a 100 amp main breaker till he has the bucks to replace
the service completely.

Anything unsafe about this rather creative idea?


The mains breaker only protects the buss that it's being tasked with
feeding....and so it follows that it's utility as to providing overcurrent
protection has absolutely nothing to do with the ampacity of the circuit
that it's being fed from.

IOW, your overcurrent protection likely resides at the primary transformer
connection.....
