What could hinder the operation of motor-operated disconnects in cold weather?

Motor-operated disconnects can encounter operational challenges in cold weather conditions, particularly due to the potential for freezing. When temperatures drop, the components of these disconnects, such as gears and moving parts, may ice up or become frozen in place. This can prevent them from opening or closing correctly, which is essential for isolating portions of the electrical system.

The presence of moisture in conjunction with freezing temperatures can create ice that physically binds the disconnect switch, leading to operational failures. Other factors, such as increased electrical resistance or component overheating, are typically more relevant in warm weather scenarios. In the cold, the primary concern shifts to the mechanical aspects of the disconnects that can be hindered by frozen conditions. Thus, the correct answer highlights the specific challenges cold weather poses to the functionality of motor-operated disconnects.
