In which locations are electrical panelboards and overcurrent devices not permitted?

Electrical panelboards and overcurrent devices are not permitted in clothes closets, bathrooms, or over steps of stairways due to safety concerns.

In clothes closets, the small space increases the risk of fire due to nearby combustibles, as these areas may store items like clothing and linens which can easily catch fire from heat or electrical sparks. Bathrooms have high humidity and wet conditions, making them unsafe locations for electrical equipment, which could lead to short circuits, malfunctions, or electric shock. Additionally, placing electrical devices over steps of stairways poses a physical hazard since it can lead to injury if someone inadvertently makes contact with the panel or device while moving up or down stairs.

These restrictions are designed to enhance safety and prevent potential accidents or fires associated with electrical installations, thereby protecting both property and individuals.
