The number and size of conductors permitted in a raceway is limited to ensure what?

The correct answer encompasses several important factors that are all relevant to ensuring safety and functionality in wiring practices.

Firstly, one critical consideration is heat dissipation. When conductors are bundled together in a raceway, they generate heat during operation due to electrical resistance. If too many conductors are crowded into a space without adequate allowance for heat dissipation, it can lead to overheating, which can damage the insulation and the conductors themselves, potentially leading to electrical failures or fire hazards.

Secondly, ease of installation is a significant factor. Limiting the number and size of conductors in a raceway ensures that installers can work efficiently and safely. When conductors are too tightly packed, it becomes cumbersome and challenging to pull the cables through the raceway, which can increase the risk of damaging both the conductors and the raceway itself during installation.

Lastly, preventing damage to insulation during removal is an important aspect as well. If the raceway is overcrowded with conductors, the likelihood of damaging insulation increases when attempting to remove or replace individual conductors. Proper spacing and size limits help facilitate easier access and minimize the risk of insulation damage.

Together, these factors emphasize the importance of adhering to guidelines regarding the number and size of conductors in a race
