A new friend asked me.......

He has a FPE stab loc 100 amp main panel, and knows this model can
cause fires. worse his panel has many 1/2 breakers, panel is maxed out
with around 28 circuits. ABSOLUTELY JAMMED

he wonders about replacing the 100 amp panel with a 200 amp, to get 40
breakers, and swap out for now the main 200 amp breaker for a 100 amp?

he has never had a main breaker trip, his problem is FPE, and number
of circuits. h
