Meter/Socket ground question

[Designer69]

If I provide the ground at the wireway as shown, is it acceptable for the socket/meter to not be grounded?

The nec says you could do it at either location
However some power companies and local authorities have a say of where they want it

The meter socket has a factory neutral/ground bond so it is bonded (some meter sockets, usually more on the commercial end, will have a removable bond ).

Thanks. So then do I show a ground conductor from the meter to the wireway? (3 wires + ground)

You install GEC at the service disconnect(s) or any point ahead of them, up to the point of connection to the service drop or lateral or other overhead/underground service conductors.

you bond everything containing service conductors to the grounded service conductor.

beyond the service disconnecting means you bond raceways/enclosures to the equipment grounding conductor, and keep the grounded conductor isolated.

No.

The meter enclosure, the wireway and the disconnect will all have the neutral bonded to their enclosures. There is no "ground" run with the service entrance conductors.

Ah ok, so you include the EGC from the disconnects on down.

What would I do without this site I don't know.

If you're installing the GEC at the wireway as shown, I believe you'd need EGCs from the wireway through the disconnects, otherwise how would the EGCs "from the disconnects on down" be connected to the grounding system?

They would be connected to the service neutrals in the disconnects.

Bonding each enclosure and adding an EGC just creates additional parallel paths for grounded conductor current.
