I noticed a friends's Square D panel, the
neutral and ground (from the utility company
feed) are connected to the same bar. And less
than an inch apart.

Shouldn't the ground be connected to the
separate ground bar?

Should I move the ground wire?

No if this is the service disconnect enclosure where the ground
electrode conductor lands and the main disconnect resides they will be
on the same bus bar.


The question is about the circuit breaker panel
in the cellar. There is a main breaker, but I'd
not call it a main disconnect.


What would you call the main disconnect?

Is there another disconnect between the pole/underground wires and the
panel? If not, the main breaker in the panel is also the main disconnect.


Mains = wire coming in from the power company.
Main disconnect = a disconnect outside the house.
(yes, I've seen these before.)
Main breaker = the breaker that shuts off power
to all the smaller breakers.

I do not call a breaker in a panel a "main
disconnect".


Just because you don't call it a "main disconnect" doesn't make you
right.

Main disconnect a disconnect outside the house.

"2008 NEC Article 230.70 (A) (1)
The service disconnecting means shall be installed at a readily
accessible location either outside of a building or structure or
inside nearest the point of entrance of the service conductors."

The "breaker panel" inside the house could be a "service panel"
or a "distribution panel". If the main breaker is enclosed in that
panel and serves as the main disconnect, then the panel is a "service
panel". If the "main disconnect" is in an enclosure by itself which then
feeds another enclosure full of breakers for the individual circuits,
then the "first" enclosure is the service panel and the "second" is the distribution panel.
