What should be taken into account to avoid jamming during cable installations?

When installing cables, it is crucial to consider the side wall pressure and clearance to avoid jamming. Side wall pressure refers to the amount of force exerted by the sides of the conduit on the cables inside it. If this pressure is too high due to insufficient clearance or improper packing of the cables, it can cause the cables to become stuck or pinched, leading to potential damage or operational issues.

Ensuring adequate clearance allows for a smooth installation process, enabling cables to move freely without getting caught or twisted. This is especially important when multiple cables are used in the same conduit or when they need to navigate bends. Factors such as the type of insulation, cable construction, and the number of cables involved also play significant roles in determining the necessary spacing and support within the conduit. Proper attention to side wall pressure and clearance ultimately facilitates a successful installation and helps maintain the integrity of the electrical system.
