Paralleling Conductors Sheeting Effects

Parallel feeders 4X 1c. 500 mcm. 5kv teck cable One being spare, direct burial accept conduits from building – transformer 15' stubbed out.

The first layer of conductors are spaced 6" apart and go in order of phases A, B, C, & C

The second layer is on top with 6" sand separation and goes in order Spare, Spare, A & B

The way it appears that vertical conduits at building end got crossed over.

The best way I could rearrange paralleling the conductors would be in order of

Spare, A,B&C the second layer on top would be in order A,B,C & Spare?

Question if I leave conductors as installed what effects there would be like sheeting currents would they be increased due to conductors arrangement or no effect?

Second question if I rearrange conductors what effects there would be?

Note the single teck conductor has 1/0 shielding – ground wire which is connected to the ground on supply end only and floating on other end.

Any advice would be greatly appreciated? Thanks
