Section 12:185-23.6 - Power circuits
Current through Register Vol. 56, No. 6, March 18, 2024
(a) Buried conductors, except ground wires, shall be insulated and installed in metal or other protective covering. Such covering shall be reinforced in places when it is subject to damage.
(b) Where conductors are joined, suitable junction boxes shall be used, or the joints secured by soldering or mechanical means so that the joint is at least equal in conductivity to the conductor. The insulation, armoring or lead covering shall be replaced in as good a condition as it was originally.
(c) All circuits leading from generating stations and substations shall be provided with automatic circuit interrupting devices so arranged that the circuit will be automatically opened at its source if the current exceeds the safe carrying capacity of the conductors.
(d) Each power conductor carrying in excess of 300 volts shall be provided with a switch capable of opening the circuit under full load.
(e) All power wires other than ground wires or armored metal sheathed wires shall be supported on or by well installed insulators, shall not touch combustible materials, nor the back or sides of working places, and when they cross other power circuits must be completely and properly insulated.
(f) Overhead high potential power lines shall be placed at least 15 feet above the ground and supported and guarded adequately to prevent contact with other circuits; providing, however, that power lines to dredges may be within three feet of the water, or when attached to a walkway shall be so located as to prevent accidental contact.
(g) Portable pumps and other portable electrical equipment shall be installed so as to constitute the minimum possible fire or contact hazard.
