is there a trick to replace a circuit breaker?

my neighbour reckons replacing a circuit breaker takes an afternoon. mine has taken three. i read somewhere that it's a bad idea, though i can't find where now. does it need anything special, or is it just patience? any help appreciated.

Not hard but it's one of the few home jobs where I'd say be very sure of yourself first. Main breaker off, then test the breaker you're replacing is dead with a tester - remember the incoming lugs in the panel stay live even with the main off. The new breaker has to be a type the panel is listed for and the same amp rating. Unclip the old one, move the wire across, snap the new one onto the bus bar. If any of that sounds unfamiliar, get an electrician in, it's a short job for them.
