What is the best source to attach ground jumpers to when using a boom truck near an energized circuit?

Attaching ground jumpers to a permanently grounded network, such as a steel tower leg, is the safest and most effective option when using a boom truck near an energized circuit. This is because a permanently grounded network provides a reliable and low-resistance path to ground, which is essential for safely dissipating any fault currents or electrical surges that may occur. The steel tower leg is typically connected to a comprehensive grounding system that is designed to ensure safety and equipment protection.

Other options may not provide as dependable a ground connection. For instance, down guy wires can provide some grounding but may not be designed or tested for that purpose, leading to potential safety risks. Similarly, a temporary driven ground rod, whether in sandy soil or otherwise, may not achieve adequate grounding resistance compared to a permanent grounding solution. Temporarily driven ground rods might also be more susceptible to displacement or ineffective grounding due to soil conditions or depth. Thus, utilizing a permanently grounded network like a steel tower leg maximizes safety and efficiency when operating near energized circuits.
