Where should a main service disconnect NOT be installed?

A main service disconnect should not be installed in a bathroom primarily due to safety concerns related to the presence of water. Bathrooms are areas with a high level of moisture, which increases the risk of electrical shock. The National Electrical Code (NEC) emphasizes the importance of keeping electrical components away from wet or damp locations to ensure safety and minimize hazards.

In contrast, areas like the kitchen, living room, and garage are more suitable for installation, as they typically do not have the same safety risks associated with excessive moisture. Kitchens can have a disconnect but should adhere to specific NEC guidelines, while living rooms and garages are often found to be appropriate locations because they do not pose the same level of electrical hazard. Hence, the bathroom's conditions make it the least suitable location for a main service disconnect.
