Electrical Question

Not sure of this set-up:
By looking at the picture there are many issues here, however, I have two questions:

  1. 200 amp main breaker- Four wires into the main posts of the breaker (right or wrong)?
  2. Ground and neutral wire in the ground post of the main breaker? (Never seen that before)

Wrong and wrong.

Yikes.

Seems like someone though they knew a little about electricity and thought they could wire it themselves.

nope nope nope refer that to a qualified sparky for proper repairs… improper wiring observed at the service panel I recommend repairs by a qualified electrician…
