VoltLedger: Electrician Tools

60 offline electrical calculators, project boards, guided circuit checks and PDF, CSV and JSON exports—built for fast, practical field work.

VoltLedger is a practical, offline workspace built for electricians, electrical technicians, engineers and contractors.

Calculate, organize and verify electrical work without an internet connection.

KEY FEATURES

• 60 electrical calculators and reference tools • Single-phase and three-phase power calculations • Voltage drop and cable sizing checks • Short-circuit and fault-current calculations • Transformer, generator and UPS sizing • Power factor correction and capacitor calculations • Grounding and electrical safety tools • Lighting, energy consumption and cost calculations • Motor current and starting-current estimates • AWG and metric conductor conversions

OFFLINE PROJECT BOARD

Create projects and organize panels and circuits directly on your device. Save calculation results to a project, monitor phase loads and identify load imbalance.

REPORTS AND EXPORTS

Generate professional PDF reports, export project data as CSV, create JSON backups and copy calculation summaries.

BUILT FOR FIELD WORK

VoltLedger works offline. No account is required. Your projects and calculations remain stored locally on your device.

Calculations are engineering aids. Always verify installation conditions, manufacturer data and applicable local regulations before construction or installation.
