What determines the selection of bolt on or plug on branch breakers?

Customer preference. Some feel that a bolt on connection is a better connection, however it does require occasional tightening. The plug on connection doesn`t require tightening and has a ``blow on`` connection which is supposed to grip the bus tighter as fault current increases.
