Industrial Generator Load Screening
A preliminary kVA screen using user-entered running load, motor-starting demand, and allowance. It does not select a generator model or verify transient voltage or...
Open calculatorInterrupting Rating Comparison
Compares a short-circuit study result with an entered device interrupting rating. This arithmetic comparison does not establish code compliance, equipment suitability, or a complete...
Open calculatorMotor Branch Conductor Minimum Ampacity Arithmetic
Multiplies an explicitly supplied motor table full-load current by a user-selected factor. It does not select NEC table current or conductor AWG/kcmil; verify the...
Open calculatorMotor Branch OCPD Multiplier Arithmetic
Applies a user-entered multiplier to a user-verified motor table current. NEC 430.52 device types, tables, exceptions, and adopted edition are not selected by this...
Open calculatorMotor Disconnect Rating Arithmetic
Applies a user-selected sizing factor to an entered motor current. This does not select a code factor or establish that a disconnect rating satisfies...
Open calculatorMotor Operating Current Estimate
Estimates three-phase or single-phase current from entered shaft horsepower, efficiency, power factor, and voltage. This is not NEC table full-load current.
Open calculatorMotor Overload Setting Arithmetic
Calculates an entered percentage of motor nameplate current. The correct overload percentage depends on motor and protection conditions and must be verified against the...
Open calculatorMotor Starting Current & kVA Estimate
Uses a user-entered starting-current multiplier to estimate starting current and apparent power. Prefer verified locked-rotor or manufacturer data; this estimate is not a generator...
Open calculatorMultiple-Motor Feeder Ampacity Arithmetic
Calculates 125% of the entered largest motor FLC plus entered other motor FLC and nonmotor load current. Verify the applicable NEC 430.24 method, table...
Open calculatorParallel Conductor Current Calculator
Divides a stated total current evenly among parallel conductors; it does not select conductor size or determine code eligibility.
Open calculatorPower Factor and P-Q-S Calculator
Calculates apparent power and displacement power factor from real and reactive power under a sinusoidal steady-state assumption. It does not calculate true power factor...
