What type of area should be avoided for the installation of service equipment?

Service equipment should not be installed in a sealed or poorly ventilated space because such environments can lead to overheating and can trap harmful gases, dust, and moisture that can compromise the functionality and safety of the equipment. Proper ventilation is crucial for maintaining a safe operating temperature and for ensuring that any gases released can disperse safely. Additionally, a lack of proper airflow can hinder maintenance work and increase the likelihood of equipment failures or electrical hazards, such as fires. This choice highlights a critical safety concern within electrical installations, emphasizing the need for adequate airflow and environmental conditions to protect both the equipment and the individuals who may interact with it.
