§870 Trolley wires and trolley feeder wires

Summary

Trolley wires and their feeder wires must have cutout switches no more than 2,000 feet apart and near the start of every branch line. They must also have overcurrent protection. Trolley wires, feeder wires, high-voltage cables, and transformers must not be placed inby the last open crosscut and must be kept at least 150 feet away from pillar workings. Wires must be insulated where they go through doors and stoppings or cross other power wires and cables. They must be guarded where people regularly work or pass under them, on both sides of doors and stoppings, and at man-trip stations. The Secretary or their authorized representatives can require other protections or better methods to prevent contact. Temporary guards must be used when trackmen and others work near the wires.
