This technique may look dangerous, but its safe as long as you apply very light pressure with the knife and keep your thumb on the opposite side of the cord. Fill ratios are calculated by comparing the area of an inner diameter cross-section of the inner-duct to the outer diameter cross-section area of the fiber optic cable. For optimum hauling performance, it is recommended that the cable-to-duct diameter fill ratio does not exceed 65, or as per cable spec sheet. laying uf (underground feeder) cable directly into the ground. This is known as direct burial, and if you do this, the uf cable must be at least 24 inches below the surface of the ground, to minimize the chance of the cable being pierced by routine shoveling. ultimate handyman diy tips - how to strip electrical cable - youtube.
