Wires should never come in contact with anything excepttheir insulator?:. Roof Stfuctures. If it should become necessary to runwires over a building, the wires should be supported on rackswhich will raise them seven feet above flat roofs or at least onefoot above the ridge of pitched roofs. See Fig. 4. Quard Arms. Whenever sharp corners are turned, eachcross arm should be provided with a dead insulated guard armto prevent the wires from dropping down and creating trouble,should their insulating support give way. Petticoat Insulators should be used exclusively for all out-side work, and especially on cross arms, racks, roof structuresand service blocks. Porcelain knobs, cleats or rubber hooksshould never be used for this heavy outside work. Splicing of two pieces of wire o
