Electrical Panel Schedule

The document provides details of the electrical load calculations and circuit design for three panels: a lighting and power panel, mechanical panel, and main distribution panel. It lists the circuits, descriptions, quantities, voltages, wire sizes, and calculates total load and breaker sizes for each panel. The main distribution panel is designed with a 150A breaker and serves the other two panels with 3-phase power.
