Drip Loop
Definition and meaning of Drip Loop in real estate.
Drip loop is a downward sag in the overhead electrical service wires just before they enter the service mast or weatherhead of a building. It prevents rainwater from flowing along the cable and into the electrical system.
In more detail
Gravity causes rainwater to run down the utility lines toward the house. By forming a U-shaped loop in the wire below the level of the entrance cap, the water is forced to pool at the bottom of the curve and drip off onto the ground.
Without this loop, water can enter the conduit, travel into the main electrical panel, and cause corrosion, short circuits, or electrical fires. Utility providers and electrical codes strictly regulate the shape and height of drip loops to ensure safety.
