I've used tray cable many times for temp. repairs in the winter when it would be impossible to pull new wires up here in the cold cruel north otherwise known as Maine [Linked Image]. 7 or 9 conductor tray cable, wire tied to a cable, strung from the building to the gas pump canopy, down the canopy pole, out across the island in a pipe, in the side of the dispenser and up comes the pump again [Linked Image]. The state of Maine is pretty lenient on temp. fixes
