Can ground wires be twisted together?
There needs to be a connector there, tying all the ground wires together. Some electricians get into the lazy habit of simply twisting ground wires together and leaving them that way, with no wirenut, dead-end compression joint, or solder to hold them together.
Can ground wire be attached to metal box?
Contact between an attached device (such as a light switch or outlet) and the metal box completes the grounding contact. Even if the device does not complete the ground, Romex or NM wiring can always be used with metal electrical boxes by attaching the bare or green grounding wire to the box by a screw.

No matter the method, it’s important that the ground circuit provides an unbroken path to the earth. Ground wires must be firmly connected at all points.
What happens if ground wire is not connected?
One problem with this arrangement is that if the ground wire is broken or disconnected, it will not be detectable from the operation of the appliance since the ground wire is not a part of the circuit for electric current flow.

If an ungrounded outlet has GFCI protection, it is legal to put a grounded receptacle there. However, the receptacle must have the “GFCI Protected” label, and it must also have a “No Equipment Ground” label. So that settles it. It’s legal if those labels (and GFCI protection) are present.
How do you ground an outlet to a metal box?
If a metal box is being used, best practice is to insert a green grounding screw into the threaded hole in the back of the box or enclosure. The equipment-grounding wires then connect to the screw, making the metal box part of the grounding system.
How much does outlet grounding cost?
