Entrance cap
Waterproof cap, also called weatherheads, mast heads or rain caps, which is placed at the upper part of an electrical mast at the point where the wires are run to the inside electrical meter. Wires hang from the pole to the entrance cap so that the entrance cap is not the low point in the downhill run from the pole because water will run to the low point before dripping to the ground. Wires enter the entrance cap at an upward angle through a tight insulator. Water is further stopped from getting through the entrance cap because of this entrance angle.
