Just got 1958 home. Several outlets show open grd. Isolated one direct from breaker box to outlet. Has 3 wire. Blk to breaker, white to small bar, ground is twisted to other bare copper but does not appear to go anyplace. Is it OK to put bare copper to small bar for ground. Switches and ceiling lights are OK
If I understand you correctly, Yes you can take all those grounds and tie it to one wire that comes from the bar. The wire should be the same size as the largest wire in the bunch. This is also known as bonding and should be done if it is the main panel. Now if the bare copper wire goes out of the panel and stops and is connected to nothing, you also need to get a new wire from the bar to a ground rod outside. I am also assuming this is the main panel. Sounds like someone did some home repairs/ upgrades and didnt know what they were doing.
you can do either one, depends on $$$.
