The panelboard schedule is essential for detailing the specifications of the electrical distribution system within a building. It provides information on the voltage requirements, locates the panelboards, specifies the type of mounting, and outlines the feeder sizes necessary to ensure that the electrical system operates safely and efficiently.

This schedule not only pinpoints where the panelboards are situated but also ensures that the electrical design aligns with safety codes and operational needs. It helps in understanding the overall capacity of the electrical system, provides clarity on how power is distributed, and facilitates future modifications or troubleshooting.

In comparison, other schedules like the load schedule primarily focus on the load calculations and electrical demands of the various circuits. The service schedule outlines the utility service and main distribution characteristics, whereas the circuit schedule categorizes the individual circuits connected to the panelboard without providing detailed specifications on mounting or feeder sizes. Therefore, the panelboard schedule is the most comprehensive in addressing voltage, location, mounting type, and feeder size requirements.
