What would be a consequence of exceeding percentage occupancy of a conduit?

Exceeding the percentage occupancy of a conduit can lead to potential overheating and failure of conductors because it creates a situation where conductors are closely packed together. This increases the thermal load and limits the ability of the conduit to dissipate heat effectively. Conductors generate heat when electrical current passes through them, and when they are bundled too tightly, as would occur with an overcrowded conduit, the heat can build up to unsafe levels. Over time, this can degrade the insulation surrounding the conductors, leading to failure or even hazardous situations such as electrical fires. Therefore, maintaining the appropriate occupancy levels in conduit is crucial for the safe and reliable operation of fire alarm systems and other electrical applications.
