I think I understand all of that until the part where it enters the rig. If I have 20 amp 120 on one leg of the 50 amp feed and 30 amp 120 on the other leg of the 50 amp feed, instead of 50 amp and 50 amp, what I am having trouble with is do the two legs ever get combined on a buss or do they maintain their separate status (kind of like parallel water pipes is what I am envisioning). If they never get combined anywhere, then with the cheater box you never truly have 50 amp service but are "cheating" the rig into thinking it does but in reality instead of just 30 amp service, you now have 20 amp service going to one set of breakers as you described and 30 amp service going to the other. If I am completely off-base with this, let me know, I am just trying to learn more.
