	Follow the instructions in the manufacturer's Owner's Manual. __________________ There was a time, not long ago, when people were smarter than their phones... (tips hat to CR4 user Harley.)

	You are required to double the cross section area, of the neutral conductor, for a K-rated transformer.

	The neutral conductor must equal the phase conductor size. The neutral earth connection must be calculated to match the maximum earth fault current, which in effect is the same as a normally rated transformer. __________________ Pessimists are rarely disappointed.
