Are photovoltaic system equipment and disconnecting means allowed in bathrooms?

In the context of the National Electrical Code (NEC), installations of photovoltaic systems, including their equipment and disconnecting means, are generally not permitted in bathrooms. This prohibition is primarily due to safety concerns related to the potential for water exposure. Bathrooms are considered wet or damp locations, where the risk of electrical shock increases significantly due to the presence of water and moisture.

By keeping photovoltaic equipment and disconnecting means out of bathrooms, the NEC aims to protect both the equipment from damage due to moisture and the individuals using the bathroom from electrical hazards. The intent is to ensure that all electrical installations are conducted in accordance with safe practices that minimize the potential for accidents or failures caused by environmental conditions that are inherent to bathroom spaces.
