Combining Circuits in Your Electrical Panel: A Step-by-Step Guide

If you are a homeowner looking to add circuits to your electrical panel, you may find yourself frustrated or confused about where to start. As more and more homeowners add electric car charging stations, solar panels, and power walls, the need for additional space in the electrical panel becomes crucial. In this article, we will walk you through the process of combining circuits safely and to code, with the help of Joel Wallsman, an expert from Jefferson Electric in Indianapolis, Indiana.

Introduction

As the demand for electricity in our homes continues to grow, it's not uncommon for homeowners to find themselves in a situation where they need to create more space in their electrical panels. However, before you start messing with wires and breakers, it's important to understand the proper methods for combining circuits and the options available to you.

Assessing Your Electrical Panel

The first step in this process is to assess your current electrical panel. Many panels are not properly labeled or are completely unlabeled, making it difficult to determine which circuits are overloaded or underutilized. This is where the expertise of a professional electrician or electrical inspector can be invaluable. They can help you identify the circuits that can be combined safely and efficiently.

The Three Options for Combining Circuits

When it comes to combining circuits, there are three main options to consider, each with its own advantages and limitations. These options depend on the brand of panel you have and require careful consideration to ensure you are in compliance with electrical codes.

Option 1: Using Pigtail and Wago

For homeowners, the least intimidating option is to use a pigtail and Wago connector. This method involves properly sizing a pigtail for your circuit and connecting it to a Wago connector. The Wago connector allows you to combine multiple circuits into one, creating more space in your panel. This option is ideal for circuits with light loads, such as LED lights or smoke detectors.

Option 2: Square D Panels

If you have a Square D panel, you may have the option to use 2 conductors per breaker. This is a common feature in both HomeLine and Square D QO panels. However, it is important to consult the manufacturer's data sheet to confirm the number and size of conductors allowed for each breaker. This information can help you support your decisions when it comes to combining circuits.

Option 3: Tandem or Piggyback Breakers

The third option involves using tandem or piggyback breakers to create additional circuit space. This method is commonly used but often misunderstood. It is essential to note that not all electrical panels allow for tandem breakers, so it is crucial to check the panel's manufacturing listing and labeling to ensure compliance with the National Electrical Code. Violations of these codes can result in unsafe electrical installations.

Step-by-Step Guide for Option 1

Now, let's walk through the steps for combining circuits using the pigtail and Wago method:

1. Begin by turning off the main power to your electrical panel.
2. Remove the electrical panel cover, taking care not to damage it or knock off any breakers.
3. Assess the circuits in your panel and identify the ones that can be combined. Look for circuits with light loads, such as LED lights or smoke detectors.
4. Disconnect the conductors from the breakers you want to combine and slip them under the Wago connector.
5. Use a tug test to ensure the conductors are fully seated in the Wago connector and trim any exposed conductor.
6. Connect the pigtail to the breaker and tighten it using a screwdriver. Be careful not to over-tighten.
7. Rock the breaker back into place, ensuring it is securely seated.
8. If you are adding a 240-volt double-pole breaker, you may need to reshuffle the other breakers to create enough space.
9. Update your panel labels to reflect the changes you have made, ensuring accurate information for future reference.
10. Finally, consider installing a panel KO closer to protect against accidental contact with live parts.

Step-by-Step Guide for Option 2

For homeowners with Square D panels, the process for combining circuits is slightly different:

1. Turn off the main power to your electrical panel.
2. Remove the electrical panel cover, being cautious not to damage it or knock off any breakers.
3. Determine the number and size of conductors allowed per breaker by referring to the manufacturer's data sheet.
4. Disconnect the conductors from the breakers you want to combine and connect them to the appropriate terminals on the breaker.
5. Tighten the connections using a screwdriver, making sure not to over-tighten.
6. Rock the breaker back into place, ensuring it is securely seated.
7. If necessary, rearrange the breakers to create enough space for the combined circuits.
8. Update your panel labels to reflect the changes you have made for future reference.

Step-by-Step Guide for Option 3

Using tandem or piggyback breakers requires additional considerations to ensure compliance with the National Electrical Code. Follow these steps to combine circuits using this method:

1. Turn off the main power to your electrical panel.
2. Remove the electrical panel cover, taking care not to damage it or knock off any breakers.
3. Identify the approved slots for tandem breakers by looking for notches on the bus or referring to the manufacturer's instructions.
4. Insert the tandem breakers only in the designated slots, avoiding any violations of the electrical panel's manufacturing listing and labeling.
5. Connect the conductors to the breakers as needed, following the manufacturer's instructions.
6. Tighten the connections using a screwdriver, ensuring they are secure but not over-tightened.
7. Rock the breakers back into place, ensuring they are properly seated.
8. Update your panel labels to reflect the combined circuits and any changes you have made.

Common Mistakes to Avoid

When combining circuits in your electrical panel, it is essential to avoid common mistakes that can lead to safety hazards and code violations. Some mistakes to watch out for include:

1. Overloading circuits with heavy loads, such as sump pumps, furnaces, kitchens, and bathrooms. These circuits should remain dedicated and up to code.
2. Failing to update panel labels after combining circuits, which can lead to confusion for future maintenance or repairs.
3. Using incorrect or mismatched breakers and connectors, which can cause poor connections and potential fire hazards.
4. Not following the manufacturer's instructions and specifications for your specific electrical panel, risking violations of the National Electrical Code.

Pros and Cons of Each Option

Each option for combining circuits has its own advantages and limitations. Here is a summary of the pros and cons for each method:

Option 1: Using Pigtail and Wago

• Pros: Easy and straightforward for homeowners, suitable for circuits with light loads, cost-effective.
• Cons: Limited to circuits with light loads, may require trimming and proper seating of conductors in the Wago connector.

Option 2: Square D Panels

• Pros: Allows for 2 conductors per breaker in compatible panels, supported by manufacturer's data sheet.
• Cons: Limited to Square D panels, requires verification of manufacturer's data sheet.

Option 3: Tandem or Piggyback Breakers

• Pros: Provides additional circuit space, commonly available in many electrical panels.
• Cons: Limited to panels that allow tandem breakers, requires adherence to the National Electrical Code for proper installation.

Importance of Updating Panel Labels

After combining circuits in your electrical panel, it is crucial to update your panel labels. Accurate and up-to-date labels ensure that anyone working on or servicing your electrical system can quickly identify the circuits and their corresponding breakers. This is especially important for safety purposes and future troubleshooting.

The Future of Electrical Panels: Smart Panels

As power demands continue to increase in homes, one significant advancement in electrical panels is the emergence of smart panels. These panels offer features such as energy monitoring, load balancing, and remote access to control and monitor your electrical system. Smart panels provide homeowners with greater control, efficiency, and insight into their power consumption.
