Cost price National Electrical Code 2023 Basics: Grounding and Bonding Part 16
Connect effectively all noncurrent-carrying metal parts serving as the equipment grounding conductors to ensure electrical continuity and the capacity to carry fault current safely.
Cost price 250.148 Continuity of Equipment Grounding Conductors and
In a plastic box, continuity is maintained between the equipment grounding conductors by joining them together inside the box rather than connecting them “to” the box.

So although there isn''t a single bonding jumper as there would be if grounds and neutrals were each on their own separate bus bar, the condition is acceptable because the relevant
Cost price What is the Main Bonding Jumper (MBJ) and How to Size it?
In an electrical panel or load center, the Main Bonding Jumper (MBJ) is the conductive connection that bonds (connects) the grounded conductor (neutral) to the equipment grounding conductor and the
Cost price Article 250
We bond so that metal parts of electrical raceways, cables, enclosures, and equipment are connected to the supply source via an effective ground-fault current path.

For example, if using a metal surface-mounted box where one of the insulating washers is removed such that the yoke of the receptacle makes metal-to-metal contact with the box, a bonding jumper is not
Cost price What is Main Bonding Jumper and Neutral Disconnect Link?
Loose or otherwise missing MBJ can lead to unstable phase-neutral voltage if transformer X 0 is not grounded. MBJ plays critical part in routing feeder side ground fault current to the neutral
