Add New Electrical Circuit

Adding a new electrical circuit can be a useful way to provide more power to your appliances, lights or outlets. However, it is also a complex and potentially dangerous task that requires careful planning, preparation and safety precautions. Here are some basic steps to follow when adding a new electrical circuit:

1. Turn off the power to the main breaker box and test the wires with a voltage tester to make sure they are not live. You may also need to get a permit from your local building authority before starting the work.
2. Determine the best way to run the wire from the breaker box to the new outlets for the new circuit. You will need to choose the appropriate wire size and type for the circuit. For example, if you are running a 15 amp circuit, you can use 14/2 wire. If you are running a 20 amp circuit, you will need to use 12/2 wire¹.
3. Cut holes for the new outlets in the walls or ceilings where you want them. You can use a stud finder to locate the studs and a drywall saw to cut the holes. You will also need to drill holes in the studs or joists to run the wire through them.
4. Fish the wire down from the attic or basement to the outlet locations. You can use a fish tape or a coat hanger to pull the wire through the holes. Leave some extra wire at each end for connections.
5. Install the new boxes and outlets at the outlet locations. You will need to strip the wire ends and connect them to the terminals of the outlets. Follow the color coding of the wires: black for hot, white for neutral and green or bare for ground. Secure the outlets to the boxes with screws and cover them with faceplates.
6. Install the new breaker and connect the wire at the breaker box. You will need to find an empty slot in the panel and snap the new breaker into place. Then, strip the wire ends and connect them to the terminals of the breaker. Again, follow the color coding of the wires: black for hot, white for neutral and green or bare for ground. Make sure the connections are tight and secure.
7. Label the new circuit and turn the power back on. You can use a marker or a sticker to label the new circuit on the panel cover. Then, turn on the main breaker and the new breaker and test the outlets with a voltage tester or a lamp. If everything works, you have successfully added a new electrical circuit.

Adding a new electrical circuit is not a simple DIY project. It requires skill, knowledge and caution. If you are not confident or experienced in electrical work, you should hire a licensed electrician to do the job for you.
