1. What is the Electrical Panel Size Calculator?

This calculator estimates the recommended electrical panel size (in amps) based on the square footage of a building or space. It uses a standard calculation of 0.5 amps per square foot.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Square Feet — Total area of the space in square feet
• 0.5 amps/ft² — Standard electrical load factor

Explanation: This calculation provides a basic estimate for residential electrical panel sizing based on square footage.

3. Importance of Proper Panel Sizing

Details: Proper electrical panel sizing is crucial for safety, preventing overloads, and ensuring adequate power distribution throughout the building.

4. Using the Calculator

Tips: Enter the total square footage of your space. For more accurate results, consult with a licensed electrician who can account for specific electrical loads.

5. Frequently Asked Questions (FAQ)

Q1: Is 0.5 amps/ft² appropriate for all buildings?
A: This is a general estimate for residential properties. Commercial spaces may require higher capacity.

Q2: What are common panel sizes?
A: Residential panels are typically 100, 150, or 200 amps, while larger homes may need 400 amps.

Q3: When should I upgrade my electrical panel?
A: Consider upgrading if adding major appliances, experiencing frequent breaker trips, or if your panel is outdated.

Q4: Are there other factors that affect panel size?
A: Yes, including number of circuits, appliance types, and local electrical codes.

Q5: Should I use this for final electrical planning?
A: This provides an estimate only. Always consult with a licensed electrician for final design.
