What is the common use for ductwork in electrical installations?

Ductwork in electrical installations serves primarily as a system for ventilation. This involves the distribution and circulation of air within buildings, contributing significantly to indoor air quality and temperature control. Proper ventilation ensures that electrical equipment remains cool during operation, helping to prevent overheating and potential failure.

While suspension, insulation, and protection are important aspects of electrical installations, they do not align with the primary function of ductwork. Suspension might refer to the physical support of electrical components, insulation pertains to materials that prevent electrical currents from causing harm, and protection typically relates to safeguarding circuit components from damage or fault conditions. In contrast, ductwork's role in moving air makes it critical for maintaining a safe and efficient working environment in electrical systems.
