I had talked to an electrician on the phone and he said something like

panel.

It certainly does no harm, except to your wallet, for him to install a ground
busbar in the service panel -- but it does no good either: since Code requires
ground and neutral to be bonded together in the service panel, electrically
they're all one bar anyway.
