What precaution is advised by most power suppliers regarding meter pole installations due to the danger from lightning?

Connecting the grounding wire to the neutral at the top of the meter box is advised as it provides a path for lightning-induced surges or electrical faults to safely dissipate into the ground. This practice helps to protect both the electrical system and any connected equipment from damage that could occur due to lightning strikes.

Grounding at the meter box ensures that the neutral, which normally serves as a return path for electrical current, is also linked to the grounding system. This can help maintain the system's stability and reduce the risk of voltage spikes affecting electrical devices. Proper grounding is a critical safety measure in electrical installations, particularly in areas prone to storms and lightning activities, reinforcing the need for secure installations to minimize risks.
