ElectriCalc 2.2

ElectriCalc by SLK Electronics L.L.C. is a modern electrical calculation and reference tool designed for electricians, engineers, technicians, and students. It streamlines day-to-day design and troubleshooting by turning complex formulas into fast, reliable results—so you can focus on building safe, efficient systems.

Key capabilities

• Conductor sizing and voltage drop: Copper or aluminum, AWG or mm², single- or three-phase, with configurable temperature, length, and load.
• Overcurrent protection guidance: Helps you select standard breaker and fuse ratings with adjustable continuous-load and ambient assumptions.
• Load calculations: Branch circuits, feeders, and panels with demand factors and diversity options.
• Conduit fill and pulling: Common conduit types and insulation categories with fill percentages.
• Motor calculations: Estimated full-load current, starting current considerations, and typical overload ranges.
• Short-circuit and available fault current estimates: Transformer kVA/impedance and feeder data inputs to approximate fault levels.
• Transformer and power conversions: kW/kVA/kVAR, power factor, single- and three-phase systems, delta/wye.
• Energy and cost estimators: Run-time, consumption, and cost projections for planning and comparison.
• Flexible units and preferences: Imperial/SI units, °F/°C, 50/60 Hz, and customizable defaults.
• Project organization: Save, label, and revisit calculations to maintain consistency across jobs.

Why ElectriCalc

• Fast, accurate, and easy to use, with clear inputs and results you can trust.
• Built on established industry formulas and common reference tables.
• Helpful for initial design, verification, estimating, and field checks.

Note: ElectriCalc is an informational tool and does not replace professional judgment. Always verify results against current local codes and standards (such as NEC/IEC) and your organization’s practices.
