It is a Listing THING. Not all connectors are listed for more than one Wire.
One buss bar says nothing in the installation instruction and the next says 2 wires twisted.
110.3 Examination, Identification, Installation, and Use of Equipment.
FPN: Suitability of equipment use may be identified by a description marked on or provided with a product to identify the suitability of the product for a specific purpose, environment, or application. Suitability of equipment may be evidenced by listing or labeling.
Most Primary Reference is:
Be aware of points such as:
250.68 Grounding Electrode Conductor and Bonding Jumper Connection to Grounding Electrodes.
B) Effective Grounding Path. The connection of a grounding electrode conductor or bonding jumper to a grounding electrode shall be made in a manner that will ensure an effective grounding path. Where necessary to ensure the grounding path for a metal piping system used as a grounding electrode, bonding shall be provided around insulated joints and around any equipment likely to be disconnected for repairs or replacement. Bonding jumpers shall be of sufficient length to permit removal of such equipment while retaining the integrity of the grounding path.
408.41 Grounded Conductor Terminations.
Each grounded conductor shall terminate within the panelboard in an individual terminal that is not also used for another conductor.
Exception: Grounded conductors of circuits with parallel conductors shall be permitted to terminate in a single terminal if the terminal is identified for connection of more than one conductor.
SEE ALSO
Definitions:
Connector, Pressure (Solderless). A device that establishes a connection between two or more conductors or between one or more conductors and a terminal by means of mechanical pressure and without the use of solder.
110.14 Electrical Connections.
A) Terminals. Connection of conductors to terminal parts shall ensure a thoroughly good connection without damaging the conductors and shall be made by means of pressure connectors (including set-screw type), solder lugs, or splices to flexible leads. Connection by means of wire-binding screws or studs and nuts that have upturned lugs or the equivalent shall be permitted for 10 AWG or smaller conductors.
Terminals for more than one conductor and terminals used to connect aluminum shall be so identified.

Ono of my pet peeves, notice the undersized hardware used with the lug on the right hand lug and how the washers are cupping because of it.

The second lug from the right says (2) 250MCM-1/0 the lug on the far right says 600MCM-8 or 2. I can't make it out.
