Today i would like to talk about 240 as compared to 208 . The voltage 208 is a commercial voltage because it is associated with 3 phase as 240 is a residential voltage associated with single phase . In a three phase system 240 has a high leg which is often colored orange. if you were to hook a breaker up to this high leg you would blow something up that is meant only for 125 voltage .But if it is hooked up 240 you wouldn't have a problem  (Confused yet). Long story short if you want to use all the spaces you would need to have an 120/208 system . A three phase 120/240 system you would lose spaces in your panel. More about this in the next post.
