Test for electricians. Find violations.

What the inspector found:

There is no introductory circuit breaker. External lighting is connected bypassing protection devices (white wire is connected to the bus before the disconnector on phase "A")
The left circuit breaker with a rated current of 100A is connected to the busbar with conductors not designed for this load (aluminum 6mm2).
There is no general circuit breaker. The discrepancy between the rated current of the third automaton on the left (32A) and the rated current of the outgoing cable. It is visually noticeable that the insulation of the third wire from the left is heated, which led to its darkening.
Grounding leashes of different consumers are connected to the bus at one point.
Grounding leashes are interconnected by means of twisting.
There is no general circuit breaker. The neutral wires of different consumers are connected to the neutral bus using a common bolt. There is no protective cover on the front panel to prevent accidental contact with live parts.
