Published Calculators
Conductor Current Density Calculator
Reports conductor current density from current and cross-sectional area while keeping ampacity, insulation, and installation decisions separate.
Open calculator
Conductor Resistance Calculator
Calculate DC conductor resistance and conductance from resistivity, length, and cross-sectional area at an entered reference condition.
Open calculator
Wire Pulling Tension Calculator
Estimate cable pulling tension, conductor weight, sidewall pressure, and tension per conductor from a simplified pull-route model.
Open calculator
Parallel Conductor Calculator
Compares ideal and highest-loaded current per parallel conductor set with entered ampacity using total load, set count, and mismatch allowance.
Open calculator
Conductor Resistance Temperature Calculator
Estimates conductor resistance at a second temperature from a known resistance basis and temperature coefficient. The calculation does not identify conductor material or select wire size.
Open calculator
Conduit Body Fill Calculator
Estimates conduit-body fill from conductor area, conductor count, an entered splice or device allowance, and verified body capacity. It does not reproduce conduit-body tables.
Open calculator
Cable Bend Radius Calculator
Estimate cable bend geometry from a verified outside diameter, manufacturer or project bend-radius multiplier, and bend angle. Confirm the resulting radius against the cable's published requirements.
Open calculator
AWG Wire Resistance Calculator
Estimate conductor resistance from AWG size, material, conductor temperature, one-way length, and the number of conductors in the path. Verify published conductor data when resistance affects design or compliance.
Open calculator
Voltage Drop Calculator
Review circuit voltage drop and margin from load current, one-way length, conductor resistance, phase model, system voltage, and an entered drop limit. The result does not select a conductor or establish code compliance.
Open calculator
Wire Derating Calculator
Estimate adjusted ampacity from a verified base ampacity and entered ambient-temperature and bundling factors; conductor count remains a review flag.
Open calculator
Wire Size Calculator (Voltage Drop and Resistance Check)
Check conductor voltage drop and the resistance target implied by the allowed drop.
Open calculator
Ampacity Calculator
Estimate adjusted conductor ampacity from a reviewed base value and explicit adjustment and temperature factors.
Open calculator
Conduit Fill Calculator
Enter the raceway internal area, the cross-sectional area of one conductor, and the conductor count to estimate occupied area and fill ratio in square inches.
