(8) Pole wiring: Pole wiring shall be No. 12 A.W.G. stranded and be a continuous length from the junction of the underground cable or fuse to the fixture terminals. It shall be connected to the underground cable by means of a weatherproof in-the-line fuse holder. Underground cable shall be long enough to allow extension through the pole hand hole of not less than six inches.
(9) Voltage drop: Voltage drop shall not be greater than 3% from the disconnect to the last standard.
(10) Conduit: Two-inch galvanized conduit shall be installed at all locations where the underground cable crosses a commercial driveway or a proposed or existing roadway. For future use, a two-inch galvanized conduit shall be installed alongside an existing street light cable on all commercial driveways constructed after the street light cable has been installed. Conduit shall extend one foot behind the back of the curb and each end shall be provided with a plastic bushing.
(11) Splices: Splices of underground cable shall be avoided where possible. If a splice is unavoidable it shall be with an approved splice kit, or as approved by the Village Electrical Engineer.
(12) Foundation:
(a) The concrete foundation for light standards shall be 20 inches in diameter and five feet in length, for a 25-foot mounting height. Anchor bolts shall be completely hot-dipped galvanized, one inch in diameter, 36 inches long, with a four-inch angle hook at the bottom. Each foundation shall be provided with a two-inch galvanized steel conduit or P.V.C. for cable installation to the pole and a 1/2-inch by eight-foot copper welded ground rod.
(b) The concrete foundation for a disconnect (when Commonwealth is buried service) shall be 12 inches around and two feet deep.
(C) Material: All material shall be as specified below or as approved by the Village Electrical Engineer.
