Attaching ground jumpers to a permanent ground network, such as a neutral or a steel tower leg, is the most effective method for grounding a boom truck near an energized circuit. This is because a permanent ground network offers a low-resistance path to ground, which is essential for effectively dissipating any fault currents that may occur.

In situations involving energized circuits, grounding becomes critical to ensure the safety of personnel and equipment. A permanent ground, like a neutral or steel leg, is designed to carry electrical current safely and consistently, providing reliable grounding under various circumstances. This reliability significantly reduces the risk of electrical shock or equipment damage when working near live electrical lines.

Other potential grounding sources, such as insulated rubber mats or wooden posts, do not provide an effective grounding path because these materials are insulators and can prevent current from flowing to ground. A metal fence may also not be an ideal choice, as it might not be a part of a proper grounding system and could have other safety implications. Therefore, utilizing a recognized and established permanent ground network is the safest and most reliable option.
