What size breaker do I need for a 60 amp subpanel?

Subpanels and Breakers

You might need to set up a subpanel to distribute electricity to several circuits as a homeowner or someone who works with electrical systems. Choosing the right size of the breaker is one of the most important factors to take into account when working with a 60 amp subpanel. This article will walk you through choosing the appropriate breaker size for a 60 amp subpanel and offer helpful tips to create a reliable and effective electrical system.

 What is a Subpanel?

A second electrical panel attached to the main electrical service panel is referred to as a “subpanel,” sometimes known as a “breaker box” or “circuit breaker panel.” In order to install additional circuits and appliances without overtaxing the main panel, it acts as a supplementary distribution point for power. Large residences, business buildings, and workshops frequently employ subpanels.

 Importance of Breakers in Subpanels

Breakers are essential parts of subpanels because they serve as safety measures to guard against overload or short circuits on the electrical circuits. The breaker trips when the current exceeds acceptable limits, stopping the flow of power and averting potential electrical dangers including fires or equipment damage.

Determining the Breaker Size for a 60 Amp Subpanel

 Load Calculation for Subpanels

You must determine the subpanel’s load before choosing the right breaker size. Total all the appliances and gadgets that will be connected to the subpanel in terms of amperage. To guarantee that the electrical system has enough capacity, it is crucial to take into account any future increases.

 Ampacity Rating of Wires

Another important thing to take into account is the wires’ ampacity rating. The cables bridging the subpanel and main panel must be able to carry the heaviest load possible without overheating. Verify the wire’s ampacity rating to make sure it can securely transport the subpanel’s needed current.

 Selecting the Right Breaker Size

Consider the ampacity of the cables and the load estimate when choosing the appropriate breaker size for a 60 amp subpanel. The subpanel’s capacity and the ampacity of the cable should match the breaker’s amperage. Typically, a 60 amp breaker would be used for

Installation of the Breaker in a Subpanel

Safety Precautions

Make careful to take all essential safety precautions before attempting to install a breaker in a subpanel. To reduce the chance of receiving an electric shock, turn off the primary power source. It’s preferable to ask a licenced electrician for advice if you have any questions concerning the installation procedure.

 Step-by-Step Installation Guide

  • Disconnect the primary power source.
    To gain access to the inside, open the subpanel’s lid.
    Attach the breaker by fastening it securely to the mounting rail.
    Push the breaker firmly onto the connecting point to attach it to the bus bar.
    Make sure the wires are properly tightened when you connect them from the main panel to the breaker terminals.
    Verify each connection a second time, and fasten any loose wires.
    Turn on the main power supply after closing the subpanel’s lid.


Can I use a higher amperage breaker for my subpanel?

It’s crucial to utilise the right breaker size according to local electrical rules and manufacturer recommendations. Using a breaker with a greater amperage rating might result in hazardous overcurrent conditions and harm electrical equipment.

 What happens if I use the wrong size breaker for my subpanel?

Using the incorrect size breaker can result in a number of problems, such as breaker trippage, wire overheating, and potential fire risks. Always use the correct breaker size depending on your wire ampacity and load estimate.

 How can I add more circuits to my subpanel?

You must make sure that your subpanel has the capacity to handle the extra load before adding new circuits. Make a load calculation, and if required, think about updating the subpanel. To guarantee a secure installation, talk to a qualified electrician.

 Can I install a subpanel myself, or should I hire a professional electrician?

Although it is feasible to install a subpanel on your own, a qualified electrician is advised. A licenced electrician has the knowledge to guarantee a safe and code-compliant installation since electrical work may be dangerous.

How often should I upgrade my subpanel?

The amount of capacity available and the frequency of subpanel upgrades depend on the electrical requirements of your family. Consider upgrading to a bigger capacity subpanel if you notice that your subpanel trips frequently or if you need to add extra circuits.
