Focused tools for a first pass on industrial load & motor projects.
Industrial Load & Motor
Computes demand factor, load factor, and average-to-connected utilization from user-entered facility values. Flags inconsistent input relationships without inferring NEC demand allowances.
Open calculatorIndustrial Load & Motor
Summarizes measured phase currents against separately entered panel bus and main overcurrent-device ratings. It also estimates phase balance and a maximum-phase equivalent kVA. This...
Open calculatorIndustrial Load & Motor
Builds a per-load real/reactive power schedule from electrical input kW, shaft hp, or nameplate kVA, then applies a user-entered simultaneity factor to each load....
Open calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
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 calculatorIndustrial Load & Motor
Summarizes three measured phase currents or apparent-load values using the same measurement basis on all phases. It reports arithmetic imbalance only and does not...
Open calculatorIndustrial Load & Motor
Applies a user-selected design factor to motor nameplate current to calculate a generic current target. Final drive selection must follow manufacturer sizing and overload...
