Steps:
1. Use diagonal-cutting pliers to sever all wires inside existing electrical panel.
2. Unscrew and remove old electrical panel from the wall.
3. Screw a large ¾-inch-thick plywood panel to the wall for mounting the new electrical panel. 4. Feed the SE cable through the top of the new electrical panel, then screw the panel to the plywood. Use a torpedo level to ensure the panel is level.
5. Make all the electrical connections inside the electrical panel.
6. Feed the house circuits into the panel, making sure each cable passes through a cable connector.
7. Connect the bare-copper ground wires and white-insulated wires to the ground and neutral bar inside the panel.
8. Plug new circuit breakers into the bus bar.
9. Run the main ground wire from the bottom of the electrical panel to the copper water main.
10. Have the utility company reconnect the electrical cables to the exterior of the house.
11. Label each breaker with the correct house circuit.
