    Power Distribution Panelboards

    The definition of power distribution panelboards.

    While panelboards come in a variety of types, there are commonly split into two categories: lighting panelboards and power distribution panelboards, also called power panels, or electrical panelboards. Power distribution panelboards are typically larger and are more commonly found in industrial and commercial applications.

    According to 2005 NEC Article 408, the main difference between these 2 types of panelboards is the percentage of the overcurrent devices that are protecting lighting and appliance circuits.

    If less than 10% of the circuit protection devices are protecting lighting and appliance circuits, then the panelboard is defined as a power distribution panelboard by default. In other words, less than 10% of the circuit protection devices are rated at 30A or less in power distribution panelboards.

    Heavy-duty power calls for a power distribution panelboard.

    As of 2008, the NEC limitations on panelboards have been relaxed, meaning they do not necessarily need to meet these exact specifications in order to qualify as one panelboard or another; however, this distinction is still commonly-used when categorizing panelboards. Power distribution panelboards are typically used for heavier power-consuming devices like motors, generators and other large electrical equipment.

    It’s also important to remember that when mounting your power panelboard, the highest mounted device must be no higher than 6’6” above the floor.
