Theoretical DC voltage drop
Calculates approximate voltage drop for a simple DC circuit with outgoing and return conductors.
Voltage drop percent
Converts voltage drop to a percentage of nominal voltage.
Theoretical three-phase voltage drop
Calculates simplified voltage drop in a balanced three-phase system from per-length parameters.
Cable current density
Calculates current density as current divided by cross-sectional area.
Cable resistance from resistivity
Calculates resistance of a uniform conductor from resistivity, length, and cross-sectional area.
DC two-wire voltage drop
Helper calculation for DC voltage drop from current, resistance per meter and length; it is not standards-based conductor sizing.
Single-phase voltage drop
Helper calculation for simplified single-phase voltage drop from resistivity and area; it is not standards-based conductor sizing.
Three-phase voltage drop from resistivity
Helper calculation for simplified three-phase voltage drop from resistivity and area; it does not replace standards-based calculations.
Cable power loss
Helper calculation for cable power loss from current and resistance; it is not an allowable-load assessment.
AWG wire resistance and mass
Calculates AWG geometry, resistance, metal mass, and optional voltage drop and power loss.
AWG to conductor diameter and area
Calculates diameter and solid circular conductor area for AWG sizes from 4/0 to 40.
