New construction GA. These are typical. I believe it is a grounding/bonding bus bar for exterior mounted communication/cable equipment. The electrical service is grounded via an UFER which is visible in the garage.
I also have concerns the bond wire is painted, is that also a problem?
Thanks!
Why would you think painting a bond wire is a problem?
Yep. That’s it. See them on every new home around here.
They usually are. No biggie. If the thin latex paint isn’t scraped off, then the set screw will do it when tightened on the wire.
Don’t see any issues with painting the copper wire. Box appears to be what you mentioned it was as long as it attached securely.
It’s a grounding/bonding terminal for communication systems required by NEC. What if the GEC was insulated, would that be a problem? how is paint any different 
There is a bond screw which is tightened against the bond wire. Paint MAY impair the connection. But I doubt it.
The code calls them intersystem bonding terminals. As said above they are now required.
This was my thinking; When I peered down inside and looked at the set screw, the set screw was definitely tightened against painted wire. I was mildly concerned this may impede a good ground connection.
But I agree with Michael and the rest of you. Thanks everyone.
Thanks for the help and the terminology.
The paint should be stripped at the terminal connection, just like an insulation would be. You asked about painted GEC, not the connection/termination
Yep, Jim has the terminology. 
Urinal for the garage… 
Here’s the relevant NEC code section:
250.94 Bonding for Communication Systems. Communications system bonding terminations shall be connected in accordance with (A) or (B).
(A) The Intersystem Bonding Termination Device. An intersystem bonding termination (IBT) for connecting intersystem bonding conductors shall be provided external to enclosures at
the service equipment or metering equipment enclosure and at the disconnecting means for any additional buildings or structures. If an IBT is used, it shall comply with the following:
(1) Be accessible for connection and inspection.
(2) Consist of a set of terminals with the capacity for connection of not less than three intersystem bonding conductors.
(3) Not interfere with opening the enclosure for a service,
building or structure disconnecting means, or metering
equipment.
(4) At the service equipment, be securely mounted and electrically connected to an enclosure for the service equipment, to the meter enclosure, or to an exposed nonflexible metallic service raceway, or be mounted at one of these enclosures and be connected to the enclosure or to the grounding electrode conductor with a minimum 6 AWG copper conductor.
(5) At the disconnecting means for a building or structure, be securely mounted and electrically connected to the metallic enclosure for the building or structure disconnecting means, or be mounted at the disconnecting means and be connected to the metallic enclosure or to the grounding electrode conductor with a minimum 6 AWG copper conductor.
(6) The terminals shall be listed as grounding and bonding equipment.
Conduit to pull in cable/communication wiring. I think this leads to the communication hub. The home is “Cable ready” and prewired with coax and cat-5 wiring in each room.

For when all your buddies are over working in the garage?..I was thinking solo. 
This is what my friends get cuz my wife do not like them tracking their dirt thru the house.
