My circuit breaker has a 3phase in it and I was wondering if I can seperate them into three seperate breakers? The 3phase is a 30amp breaker, can I turn them into 3 15amp single phase breaker?

No and yes
No: You have answered the question yourself. If the 3 phase 30 amp is separated, you get 3 - 30 amp breakers, not 3 15 amp.
Yes, many combined breakers can be converted to a set of individual breakers. You can examine the handle of the breaker and see whether the handle is molded as a solid unit or is three handles, one from each section, with a cap to tie them together so that if one trips the other two are set off. 30 amp (or 15 amp) is not enough to unbalance the electrical load dramatically.
One thing I am not certain of is the voltage coming out of each phase. Sometimes 3 phase is fed with a separate set of lines so taking the voltage from each phase to ground does not match the 110-125 volts demanded of 1 phase appliances.

My guess would be no. Because if one of the three phases trips it would cause the others to break also. I'm not sure splitting up a 3-phase connection into 3 one phase connections is such a good idea. Any load imbalance on the 3 phases will cause large currents on the neutral line. Your utility company can get away with splitting up the phases because they monitor the loads and because so many things are connected to each phase, the loads on each phase averages out to be fairly close to the load on the other two phases, keeping the system balanced.

There is some confusion, in the qstn u said u r having 480V, coming in, but in details u says that 240V, as per you u r having an equipment that can work with either 208 or 480V, then what is the problem choose the 480V terminals and connect to the main. regarding the panel u did not explain the capacity of the breakers.

remove the breaker and replace with three separate 15amp breakers. Trying to save money on electrical wiring will burn something down. dont be an idiot
