Dave,

Below you said you were running 4 breakers, each 30 amps.  Then you said 
two of those breakers would be wired with #12 wire.  If  your breaker is 
going to be a 30 amp breaker, you must, for safety's sake  and to meet 
NEC, use at least #10 wire. You should NEVER use wire rated  less than 
the capacity of the breaker.  If you are using #12 wire,  the breaker 
should never be larger than 20 amps. The length of the run is  of no 
consideration when it comes to meeting the minimum requirement of  the 
code.
This is NOT entirely true. If you are running motor circuits you may up the

rating of the circuit breaker well over the size wire that is being used.   
However, for branch circuits the above is true, but as I have stated, NOT  
always.
