What Size Electrical Sub Panel Do I Need?

Apr 7, 2018

Understanding Electrical Sub Panels

When it comes to electrical systems in homes and businesses, electrical sub panels play a crucial role in distributing power throughout the building. These panels are additional breaker boxes that are connected to the main electrical service panel. They help manage the electrical load and provide a safe and efficient way to allocate power to various circuits.

The Importance of Choosing the Right Size Sub Panel

Choosing the right size electrical sub panel is essential to ensure optimal performance and safety of your electrical system. An undersized sub panel can lead to frequent circuit overloads, tripped breakers, and potential fire hazards. On the other hand, an oversized sub panel can be unnecessary and costly. It is crucial to assess your electrical needs accurately to determine the appropriate size for your sub panel.

Determining the Correct Size Sub Panel

Several factors need to be considered when determining the correct size sub panel for your specific needs:

1. Total Power Demand

Start by assessing your total power demand. Consider the electrical appliances, equipment, and devices that will be connected to the sub panel. Calculate their electrical load, typically measured in amps, and add them together to get an estimate of your total power demand.

2. Future Expansion

It is essential to take into account future expansion plans when selecting the size of your sub panel. If you are planning to add more electrical appliances or circuits in the future, you'll want to factor in their potential electrical load when determining the size of the sub panel.

3. Circuit Capacity

Consider the number of circuits you will need in your sub panel. Each circuit has a maximum capacity, typically measured in amps. Ensure that the sub panel you choose has enough slots and capacity to accommodate your current and future circuit requirements.

4. Diversity Factor

Take into account the diversity factor, which refers to the likelihood of all electrical devices running at the same time. Not all devices will be at maximum load simultaneously. Consider the usage patterns and determine a reasonable diversity factor to avoid overloading the sub panel.

Consulting with a Professional Electrician

While the information provided can serve as a helpful guide, it is strongly recommended to consult with a professional electrician for an accurate assessment and recommendation. A licensed electrician will have the expertise to evaluate your specific electrical needs, analyze your existing electrical system, and recommend the ideal size for your electrical sub panel.
