Electrical Load Formula:
From: | To: |
Definition: This calculator estimates the total electrical load in kilowatts (kW) by summing the power consumption of individual appliances.
Purpose: It helps homeowners and electricians determine the total power requirements for a home's electrical system.
The calculator uses the formula:
Where:
Explanation: The power of each appliance is summed in watts, then converted to kilowatts by dividing by 1000.
Details: Proper load calculation ensures your electrical system can handle all appliances safely without overloading circuits.
Tips: Enter the wattage of each appliance (found on nameplates or manuals). At least one appliance must be entered.
Q1: What's the difference between watts and kilowatts?
A: 1 kilowatt = 1000 watts. We use kW for larger power measurements.
Q2: Should I include all appliances?
A: Include all regularly used appliances for an accurate total load.
Q3: What if I don't know an appliance's wattage?
A: Check the nameplate or manual, or use: Watts = Volts × Amps.
Q4: How does this relate to circuit breakers?
A: Total load should not exceed 80% of your main breaker's capacity.
Q5: What's a typical home electrical load?
A: Most homes range between 3-10 kW, depending on size and appliances.
