I've got an application where I have shipping container that contains a piece of equipment(incinerator). This incinerator requires 120V/1PH/60HZ/30A service. The container also has another accessory circuit (lights, recept., and exhaust fan) @ 120V/1PH/60HZ/20A. These two circuits terminate at a 4-circuit loadcenter, with a 50A main. Under typical use, the equipment circuit will be using ~15A (running). The accessory circuit will be using just a fraction of that load (in the 2-3A neighborhood) I need to provide a generator to power this unit. I've got a 6kW generator at my disposal that is equipped with the following:
2 - 125V-20A duplex receptacle(s)(5-20R) - 2P3W
1 - 125/250V-30A socket (L14-30R) - 3P4W
1 - 250V-30A socket (L6-30R) - 2P3W
All the background aside, here is the question. I had originally planned on connecting the generator to the loadcenter via the 125/250V-30A connection, using the 2 hots (120V) to feed opposite sides of the bus in the loadcenter, with the ground and neutral shared with both circuits. My question is, in my application will the difference in actual current used by the two legs adversly effect the generator? I need to provide 30A to the equipment circuit, and I am somewhat stuck with the generator I've got. I have considered installing a 240/120 transformer between the generator and loadcenter which would essentially evely share the 240 among the two 120V loads. I am limited on space and cost and quite frankly a 10kVa Transformer takes up a substantial chunk of both. Can I safely run these two circuits off of the 125/250V-30A (3P4W) with out overloading the generator or damaging it?
Thanks for your input,
