adding a subpanel in garage - IOT Wiring Diagram

Adding a subpanel in your garage is a great way to extend your home or business's existing electrical system. With the addition of a subpanel, you can add more circuits and outlets for your tools, entertainment systems, and business equipment. Installing a subpanel does require knowledge of electrical wiring and needs approval from your local government prior to installation.

The first step to adding a subpanel in your garage is to measure the existing electrical load. Make sure the power coming from the main panel is enough to support the new subpanel. This means adding up the wattages of any electronics and appliances you have in your garage and ensuring the amount does not exceed the total amperage rating of the circuit breakers. After determining the amperage rating of the main panel, you'll need to select a breaker that matches the wattages of your devices.

After selecting a breaker, you'll need to purchase the necessary supplies. Depending on the size of the subpanel, this could include a saddle-back disconnect switch, a 20-amp double-pole breaker, an electrical box, and assorted wiring materials. Once all the materials have been acquired, you'll need to run a feeder wire from the main panel to the subpanel, running it through the crawlspace or inside the walls. You can also use armored cable to run the wire through.

Once the feeder wire is installed, you'll need to install the subpanel itself and hook the wires up properly. Make sure to mount the subpanel in a dry area using lag screws. Then attach the breakers and the grounding bar. Finally, place the cover over the subpanel and test it to ensure it works properly. Once all these steps are complete, you can then finally enjoy the additional outlets and power you get from the subpanel!
