PowerCalc

PowerCalc (by Electric Power Calc) is a cloud-first electrical design tool aimed at automating the power-distribution design workflow for buildings. Its core promise is dramatic time savings and code-compliant outputs: with just three inputs per circuit (load kVA, load type and number of poles) PowerCalc claims to produce over 300 NEC/IEEE-compliant results and automatically generate one-line diagrams, panel schedules and related distribution artifacts. That central automation pitch — “auto-calc” that propagates changes upstream and downstream across the model — is the software’s defining value proposition. User interface and ease of use are clearly positioned as strengths. PowerCalc’s workflow revolves around simple circuit-level inputs and a live graphic one-line overview so users see immediate visual feedback when values change. The vendor emphasizes an “easy” design goal (three inputs per circuit) and offers video walkthroughs and a user manual to flatten the learning curve — useful for engineers who want to trade repetitive arithmetic for guided modeling. In practice this yields a shallow learning curve for standard building projects, although power-system specialists may still need to validate advanced edge cases.
