Electrical Calculators & Solvers

Sizing tool that factors in continuous load multipliers, conductor materials (copper vs. aluminum), and thermal limit constraints to select the appropriate AWG or kcmil cable size.

Computes terminal voltage, voltage drop magnitude, and percentage drop over long distance wiring runs. Helps prevent device malfunctions and safety issues caused by voltage dip.

Determines three-phase and single-phase motor Full-Load Amperes. Ideal for sizing protective circuit breakers, starters, overload relays, and motor feed conductors.

Calculates the nominal full load currents on both primary and secondary windings. Outputs turns ratios and safety factor sizing guidelines (125% current ratings).

Sizes capacitor bank ratings (kVAR and microfarads) to raise power factor, reducing utility lagging charges and restoring system current carrying capacity.

Instantly solves for Voltage ($V$), Current ($I$), Resistance ($R$), or Power ($P$) by supplying any two variables. Extremely helpful for troubleshooting circuits and prototyping.
