Hard to answer this question with out the load type and amperage. Depending on the type of load some wire feeders have to be increased by 25%. For a correct answer state what the three phase load is and its wattage or amperage.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized
