JANUARY 05, 2020 Schedule of Loads Acosta, Kurt Francis H

This document provides the circuit details for a proposed two-story house, including 17 circuits. It lists the number of outlets, circuit description, voltage, wattage, amperage, conductor size and color code for each circuit. The total load for the house is 16880 watts and 73.39 amps. Based on the calculations, a 2-22.0 mm2 THHN + 1-8.0 mm2 THHN feeder is required in a 32mm diameter RSC conduit, with a 90AT, 100AF, 2P, 240V, 20kAIC main circuit breaker. Any additional electrical loads beyond what is designed would require redesign of the electrical system.
