Busbar Calc is designed for preliminary planning and study. It is not a standards reference, certified sizing tool, thermal simulation, manufacturer table, or substitute for applicable electrical codes, manufacturer data, enclosure conditions, or qualified engineering review. Results must be independently verified before design, procurement, installation, or energization.

No account is required. Calculation history is stored locally on the device. Version 1 has no advertising, billing, analytics, cloud sync, or social sharing.
