Where is the 4th wire of a 3 phase 4 wire NQOD panel connected?

The 4th wire should be connected to the neutral. The neutral bars are located on both sides of the main. One side has the incoming lug connection. Both bars are bussed together , however the connection may not be visible due to being covered by panel insulation. The ground bar, purchased separately, is mounted directly to the back plate of the panel enclosure.
