Both types of wire meet US electrical codes, and you can purchase insulated wire by the foot at any local hardware store. To connect the ground rod to other parts, you can use bare copper or insulated THHN wire. If the ground electrode is too small, you should use a pipe electrode.

But, if your building doesn’t have a ground rod, you can use a ground pipe. This is the standard size for ground electrodes. The conductor for the ground electrode must be at least 5/8 inch in diameter. Ground rods of smaller diameter are also acceptable. Ground electrodes must be at least 8 feet in length.
