How to Add a Subpanel

Adding a subpanel can be a good option if you need to expand your home's electrical system but don't have enough space in your main panel or need to isolate certain circuits. Here are the general steps to add a subpanel:

1. Determine the subpanel's location: Choose a location that is easily accessible and has enough space to mount the subpanel. It should also be close to the main panel and be in a dry, safe area.

2. Turn off the power: Turn off the main power to your home by switching off the main circuit breaker.

3. Install the subpanel: Install the subpanel by mounting it securely to the wall using screws or bolts. Run the necessary conduit and wires from the main panel to the subpanel, ensuring that they are the correct size and type for the subpanel's amperage rating. Consult with an electrician to ensure you are following local codes and regulations.

4. Connect the wires: Connect the wires from the main panel to the subpanel, including the hot wires, neutral wires, and ground wires. Follow the manufacturer's instructions and make sure to use appropriate wire connectors.

5. Install circuit breakers: Install circuit breakers in the subpanel, following the manufacturer's instructions. Be sure to label the circuits to avoid confusion later on.

6. Test the subpanel: Turn the main power back on and test the subpanel to ensure that all circuits are working correctly. Use a voltage tester to check for any stray voltage and ensure that all wires are properly grounded.

7. Have an inspection: Have the installation inspected by a licensed electrician or local building inspector to ensure that it meets all local codes and regulations.

Adding a subpanel can be a complex and potentially dangerous task, so it's always best to consult with a licensed electrician to ensure that the installation is done safely and correctly.
