Under what conditions is outdoor electrical equipment most likely to fail?

Outdoor electrical equipment is most likely to fail in extreme weather conditions or due to moisture exposure. This vulnerability arises because outdoor equipment is often exposed to a variety of harsh environmental factors such as rain, snow, high humidity, and extreme temperatures.

Moisture can lead to corrosion of electrical components, which compromises their integrity and functionality. Wet conditions can also cause short circuits or electrical arcing, increasing the likelihood of equipment failure. In addition, extreme temperatures can cause materials to expand or contract, leading to mechanical stress and potential damage.

Regular maintenance checks, while important for the upkeep of equipment, are not typically the conditions under which failures are most commonly observed. Surge protectors are designed to prevent damage from voltage spikes rather than cause it, and properly conducted voltage stability testing is a necessary process to ensure equipment operates within safe parameters, not a typical cause of failure.
