What is the primary concern when using outdoor wiring connections?

The primary concern when using outdoor wiring connections is moisture intrusion. Outdoor environments are often exposed to rain, snow, humidity, and other elements that can lead to water ingress. When moisture penetrates electrical connections, it can cause short circuits, corrosion, and ultimately lead to equipment failure or electrical hazards, including shock or fire risks.

To mitigate these risks, outdoor wiring must be properly rated for wet locations, and connections should utilize weatherproof enclosures, sealing compounds, or other means to prevent moisture from affecting the integrity of the electrical system. Choosing materials and methods that protect against moisture ensures that outdoor electrical installations remain safe and reliable over time.
