Circuit Load (Amps) = Appliance Wattage / Circuit Voltage But hold on—you can't max out the breaker! Electrical codes (like NEC) require breathing room. We follow the 80% rule : Safe Continuous Load = Circuit Breaker Rating × 0. 8 Example: Need a circuit for your 1,800W. Before we dive into calculations, let's get familiar with a few essentials: 1. Your Project's Total Power Demand This isn't just adding up wattages randomly. Think of your home as a busy kitchen—not every appliance runs at once. Do you really need the hair dryer, microwave, and vacuum running. The information provided in this document contains general descriptions, technical characteristics and/or recommendations related to ...
