Equipment frame interconnections within the isolated ground plane, the grounding of internal power supplies that power remote loads, the installation of receptacles powered from internal ac power supplies, the sizing of power plant frame grounding conductors, and "girdling" (the encirclement of a grounding conductor by a ring of ferromagnetic material) are also included in the standard.
