MEFFY - Please be careful with federal pacific! Unless the company has come up with a foolproof way of keeping the breakers in the panel - don't remove the cover unless to have to! You see the stabs on the breaker are made of copper. A full sized breaker has three tabs that stick out. They fit into a hole that looks like an E. Half sized breakers are only one half of the E. Also breakers are supposed to trip out within three cycles of an obvious overload. I worked for a utility in Western Mass and we had a test instrument for circuit breakers. Simple 15 amp FPE breakers did not trip within three cycles. It took about five minutes for the 15 amp to trip. Current going through it was 95 amps and boy was the breaker HOT! Similarly an 800 amp FPE in a U-Haul store in Mass started to fry when it developed an inter phase short AND IT STILL DIDN'T TRIP! Just be careful!
