Circuit design and reuse

Dynamically generate rules-based electrical control circuits based on components, wiring, ratings, and catalog data. Circuit Builder gives you the information to make good electrical engineering decisions that are also environmentally sustainable. Create electrical schematic designs based on wire material type, ambient temperature, maximum voltage drop, and more. Improve productivity by building commonly used circuits once, and then saving them for reuse later.
