1. What Is Load Calculation For Residential Ontario?

Load calculation for residential Ontario involves determining the total electrical load requirement for a residential property according to the Ontario Electrical Code. This ensures proper sizing of electrical service and prevents overloading.

2. How Does The Calculator Work?

The calculator uses the standard load calculation formula:

Where:

• \( Basic \) — Basic electrical load including lighting and general outlets
• \( Specific Appliances \) — Additional load from specific appliances and equipment

Explanation: This calculation follows the Ontario Electrical Code requirements for residential load calculations to ensure safe and adequate electrical service.

3. Importance Of Load Calculation

Details: Proper load calculation is essential for determining the correct electrical service size, preventing circuit overloads, ensuring electrical safety, and complying with Ontario Electrical Code regulations.

4. Using The Calculator

Tips: Enter the basic load in volt-amperes (VA) and the specific appliances load in VA. Both values must be non-negative numbers. The calculator will provide the total load requirement.

5. Frequently Asked Questions (FAQ)

Q1: What is included in basic load?
A: Basic load typically includes general lighting, general-use receptacles, and small appliance circuits as specified in the Ontario Electrical Code.

Q2: What are specific appliances?
A: Specific appliances include major electrical equipment such as ranges, ovens, dryers, air conditioners, water heaters, and other fixed appliances.

Q3: Why use VA instead of watts?
A: Volt-amperes (VA) account for both real power (watts) and reactive power, providing a more accurate representation of the total electrical load on the system.

Q4: Are there demand factors to consider?
A: Yes, the Ontario Electrical Code applies demand factors to certain loads since not all appliances operate simultaneously at full capacity.

Q5: When is professional assessment needed?
A: For complex installations, large homes, or commercial applications, consultation with a licensed electrical contractor is recommended.
