Ground pigtails are commonly used in electrical panels, junction boxes, and various electrical installations to create a reliable grounding path.
It used to be required to "maintain continuity" with the available equipment grounds at each junction box. So conduit ground and wire ground went together at each box. About ten years ago they changed the wording so you only need to ground the box with the wire ground (maintain continuity) when a splice is made in the box.
