Calculateur de Electrical Load
Estimate electrical load from voltage, amperage, and circuit count.
Formula and method
This calculator computes Usable load directly in your browser without sending data to an external server.
Mathematical formula
- Usable load:
voltage × amps × circuits × load ÷ 100
Variables and parameters
- Voltage (voltage): default value 120 V.
- Amps per circuit (amps): default value 15 A.
- Circuits (circuits): default value 4.
- Load factor (load): default value 80 %.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
