The whole thing is a brand new, unitized pump/fountain unit that floats in a retention basin.
It was specified and bought by the site manager, and installed in the pond by a different electrician. The phase converter was specified by an application salesperson, and installed by me.

I don't know why the current imbalance. The measurements are taken at the pump cable, and no other load is applied to the cable.

It's not a complicated installation. I believe it should work as installed, with equal current distribution.
