A detached garage typically has a subpanel to provide power to the garage. The subpanel is usually mounted on an exterior wall of the garage. The subpanel may have circuit breakers to protect the circuits serving the garage, or it may have fuses. To wire a subpanel in a detached garage, you will need to run a cable from the main panel in the house to the subpanel. The cable should be a type that is approved for outdoor use, such as
How To Wire A Subpanel In A Detached Garage
Installing a subpanel in a detached garage is a great way to have more circuits available for your tools, equipment, and other appliances. The following guide will show you how to wire a subpanel in a detached garage. 1. Shut off the main breaker in the main service panel. 2. Remove the cover from the subpanel and identify the circuit breakers that will be used in the subpanel. 3. Cut the wires to the appropriate length and

- Remove the knockouts from the back of the subpanel run cables from the main panel to the subpanel attach cables to breaker terminals
- Disconnect power from the main panel
- Remove the cover of the subpanel
: -Check the main breaker to ensure it is off -Remove the cover of the subpanel -Find the main breaker for the subpanel and set it to off -Connect the black wire from the main breaker to the black wire coming from the house -Connect the white wire from the main breaker to the white wire coming from the house -Connect the ground wire coming from the house to the ground bar in the subpanel -Close up the subpanel and turn
Frequently Asked Questions
Does A Garage Subpanel Need A Main Breaker?
No, a garage subpanel does not need a main breaker. A subpanel is a panel that is installed to service a specific circuit or group of circuits. The main breaker in the service panel protects the entire electrical system in the home.
How Do You Wire A Sub Panel For A Garage?
First, you need to determine the size of the sub panel. Next, you need to figure out how many amps your garage requires. Once you know the amps, you need to find the corresponding wire size. Finally, you need to figure out how to mount the sub panel.
Do Main Panels Need A Main Breaker?
A main breaker is not always necessary for a main panel. Depending on the amperage of the panel, a main breaker may be required to ensure the safety of those working with and around the electrical system.
When wiring a subpanel in a detached garage, it is important to follow the National Electric Code (NEC) to ensure safety. The NEC requires that all subpanels be wired with a main breaker and that branch circuit wiring be protected by overcurrent devices. In addition, proper grounding and bonding connections must be made to ensure the safety of the electrical system.
