How much does it cost to install a subpanel in a detached garage?

Answered by Willie Powers

The cost of installing a subpanel in a detached garage can vary depending on various factors such as the size of the garage, the amperage of the subpanel, the number of circuits needed, and the specific electrical requirements. On average, you can expect to pay between $400 and $1,750 for the installation of a subpanel.

One of the main factors that can influence the cost is the amperage of the subpanel. The amperage determines the amount of power that the subpanel can handle. Typical subpanels range from 100 to 150 amps, but it can go higher depending on the electrical needs of the garage. Higher amperage subpanels tend to be more expensive.

The number of circuits needed in the subpanel can also affect the cost. Each circuit allows for the connection of specific electrical devices or appliances. Subpanels can have anywhere from 4 to 20 or more circuits, depending on the requirements of the garage. The more circuits you need, the more complex and time-consuming the installation process can be, which can increase the overall cost.

The specific electrical requirements of the detached garage can also impact the cost. For example, if the garage needs additional wiring or upgrades to meet electrical code requirements, this can increase the cost of the installation. It is important to consult with a licensed electrician who can assess the specific needs of your garage and provide an accurate estimate.

In addition to the installation cost, you should also consider the cost of materials. This includes the subpanel itself, circuit breakers, wiring, and any necessary accessories. The cost of these materials can vary depending on the brand and quality, so it is important to discuss your options with the electrician.

It is worth noting that the cost of installing a subpanel in a detached garage can also be influenced by the location and accessibility of the garage. If the garage is located far away from the main electrical panel or if there are obstacles that make the installation more challenging, such as concrete walls or limited space, this can increase the labor and overall cost.

When it comes to the installation process, it is crucial to hire a licensed and experienced electrician. Working with electricity can be dangerous, and it is important to ensure that the installation is done safely and up to code. Hiring a professional will not only ensure the proper installation of the subpanel but also provide peace of mind knowing that the electrical system in your detached garage is safe and reliable.

The cost of installing a subpanel in a detached garage can range from $400 to $1,750, depending on factors such as the amperage, number of circuits, specific electrical requirements, and the location of the garage. It is best to consult with a licensed electrician who can assess your needs and provide an accurate estimate for the installation. Remember to prioritize safety and quality when it comes to electrical work in your garage.
