About this Web App
What does Branch Circuit Designer include, and what changed from the native source?
Look up motor full-load current and explore continuous-load protection sizing with source tables, examples and saved projects. The general OCPD tool and motor-current lookup are separate calculations. Motor overload protection and conductor design require additional checks. The Web App adds project saves, backups and printable results; native gallery collections are omitted.
