Organizing a Panel Box
Thus, if you have wires coming down from both sides, it makes most sense to divide wire groups. To facilitate this, panels typically have neutral and ground bus bars on both sides.
Cable entry into cabinet/panel -top or bottom?
The main advantage of bottom entry is that it maintains the integrity of the junction box against water. Rain and/or condensate in the conduit can destroy the wiring of a junction box in short
JLC Field Guide: Main Service
The main disconnect is housed either in the distribution panel (below) or in its own separate box. This depends in part on the location of the distribution panel.

Wires In & Out of Box
Nope. Cables come and go in any orientation. The code doesn''t care and in practice people use whatever is the most convenient for the wire they''re running.
How to Install a Cable Distribution Box Safely and Correctly?
