To quickly assess the difficulty of the text, read a short excerpt:
Manholes should be provided about every 300 feet, in order to facilitate the installation of the conductors in the duct. The exact distance be- tween manholes should be determined by conditions; in some ?ases they should be placed even closer to- gether than the figure given, while in other cases their distance apart mi gh t be slightly greater. Manholes are built of concrete or brick, and provided with a cast-iron frame or cover. The man- holes may be of square, round, rect- angular, or oval s...ec- tion, the last-men- Fig. 78. Tioned form of man- hole being probably the best, as it avoids the liability to sharp bends or kinks being made in the cable. The manhole cover may be of the same form as the manhole itself, or it may be of different form; but round or square covers are usually used. Fig. 78 shows a standard form of manhole used in New York City. This manhole is substan- tially built, and adapted for heavy traffic passing over the cover. For suburban or country work, manholes may be made of lighter con- struction.
