(a) A cable at least as large as one of the incoming power lines to the generator shall be provided for grounding the generator shell. This cable shall be permanently fastened on some part of the generator and shall be grounded in an approved manner.
(b) A suitable screen or guard shall be provided around high-voltage bushings, and a sign posted warning of high voltage. This screen or guard shall be so located that it prevents accidental contact with the high voltage circuit.
(c) In electric boilers of the submerged-electrode type, the water gage glass shall be located to indicate the water levels both at start-up and under maximum load conditions as established by the manufacturer.
(d) Electric boilers of the resistance-element type shall have at least one gage glass. The lowest visible water level in the gage glass shall be at least 1 inch (25 mm) above the lowest permissible water level as determined by the manufacturer. Each boiler of this type shall be equipped with an automatic low-water cutoff to cut off the power supply before the surface of the water falls below the visible level in the gage glass.
(e) Tubular gage glasses on electric boilers shall be equipped with protective rods or shields.
(f) The minimum relieving capacity for pressure relief valves on electric boilers shall be 3 1/2 pounds (24 kilopascals) of steam per hour per kilowatt input.
(g) All electric boilers shall be internally examined through the electric heating element, removable cover, inspection opening or handhole as construction allows.
