Total Watts Formula:
From: | To: |
Definition: This calculator estimates the total electrical power consumption by summing the wattage of individual appliances in a home.
Purpose: It helps homeowners and electricians determine the total electrical load to ensure safe operation and proper circuit sizing.
The calculator uses the formula:
Where:
Explanation: The calculator simply adds up the wattage of all appliances you enter to give the total power consumption.
Details: Proper wattage calculation helps prevent circuit overloads, ensures electrical safety, and aids in energy consumption awareness.
Tips: Enter the wattage for each appliance (found on their labels or manuals). At least one appliance must be entered. Leave unused fields blank or at 0.
Q1: Where can I find an appliance's wattage?
A: Check the appliance's label, manual, or specifications online. Some list amps and volts instead (Watts = Amps × Volts).
Q2: Should I include all appliances?
A: Include those that might run simultaneously. For a complete home assessment, include all major appliances.
Q3: What's a typical wattage for common appliances?
A: Refrigerator (150-400W), Microwave (600-1200W), LED TV (30-100W), Laptop (50-100W), etc.
Q4: How does this relate to my electricity bill?
A: Electricity is billed in kWh (kilowatt-hours). 1000W running for 1 hour = 1 kWh.
Q5: What if I only know amps?
A: For standard 120V circuits: Watts = Amps × 120. For 240V appliances: Watts = Amps × 240.
