For EGCs and GECs, the NEC allows ground wire to be either insulated or bare in most applications. I’m not aware of any case where insulation is explicitly required by the NEC for grounding conductors. It is an engineer’s/installer’s discretion to specify insulated grounding wire.
Applying the above, a groundING condcutor can often be insulated or bare but the groundED conductor needs to be insulated as you say to prevent an unintentional and non-compliant connection to grounding.
Can you run bare ground wire in EMT?
Chief Moderator. There no rule against a bare ground in emt.
Is it okay for ground wire to be exposed?
Grounding wires, especially those running through grounding rods on the exterior of your home, are exposed. The grounding wires are safe to touch unless there is an electrical surge that causes electricity to flow through the grounding wire.
Does a ground wire need to be in conduit?
The reason the CODE requires the ground conductor to be inside the conduit is for protecting the conductor from being damaged by any mechanical means e.g., gardener weed whacker. In fact, you can use PVC to house the ground conductor.
Does the ground wire have to be insulated?
A grounded wire is required by the National Electrical Code to be white or gray in color on the customer side of the meter. Grounded wires on the utility side of the system do not generally have insulation. A “grounding” wire on the other hand is a safety wire that has intentionally been connected to earth.

Does the ground wire have to be attached?
Grounding refers to the wire that runs from an outlet into the earth, inherently protecting homeowners from coming in contact with electric energy. 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.
Is it OK for ground wire to be exposed?
Grounding wires, especially those running through grounding rods on the exterior of your home, are exposed. The grounding wires are safe to touch unless there is an electrical surge that causes electricity to flow through the grounding wire.
Do ground wires need to be covered?
Bare naked ground conductor is perfect fine in certain space. The reason the CODE requires the ground conductor to be inside the conduit is for protecting the conductor from being damaged by any mechanical means e.g., gardener weed whacker. In fact, you can use PVC to house the ground conductor.
Is it OK for a ground wire to touch insulation?
If your wiring is right, the ground does not normally conduct current, so it should be fine.
Can you leave a ground wire exposed?
Grounding wires, especially those running through grounding rods on the exterior of your home, are exposed. The grounding wires are safe to touch unless there is an electrical surge that causes electricity to flow through the grounding wire.
Does ground wire need to be shielded?
The reason for shielding cables is to prevent electromagnetic radiation from leaving or entering the cable. Since the ground is tied to the chassis, the cable and chassis can be considered as being the same potential.
