When an electrical surge from the atmosphere encounters a residential structure, the immediate consequence can be dramatic. The immense energy discharged seeks the path of least resistance to the ground. This often involves traveling through the building’s wiring, plumbing, or even structural components.
The effects of such an event range from minor electrical system damage to catastrophic structural failure. The rapid heating of materials along the path of the electrical current can cause fires. Moreover, the surge can overload and destroy electronic devices connected to the electrical grid. Historically, such events posed a significant threat to dwellings constructed without modern grounding systems, leading to widespread property damage and loss.
